The goal of this assignment is to refine our JavaScript knowledge while exploring the multimedia capabilities of the browser. - -Baseline Requirements ---- - -Your application is required to implement the following functionalities: - -- A server created using Express. This server can be as simple as needed. -- A client-side interactive experience using at least one of the following web technologies frameworks. - - [Three.js](https://threejs.org/): A library for 3D graphics / VR experiences - - [D3.js](https://d3js.org): A library that is primarily used for interactive data visualizations - - [Canvas](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API): A 2D raster drawing API included in all modern browsers - - [SVG](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API): A 2D vector drawing framework that enables shapes to be defined via XML. - - [Web Audio API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API): An API for audio synthesis, analysis, processing, and file playback. -- A user interface for interaction with your project, which must expose at least six parameters for user control. [dat.gui](https://workshop.chromeexperiments.com/examples/gui/#1--Basic-Usage) is highly recommended for this. You might also explore interaction by tracking mouse movement via the `window.onmousemove` event handler in tandem with the `event.clientX` and `event.clientY` properties. Consider using the [Pointer Events API](https://developer.mozilla.org/en-US/docs/Web/API/Pointer_events) to ensure that that mouse and touch events will both be supported in your app. -- Your application should display basic documentation for the user interface when the application first loads. This documentation should be dismissable, however, users should be able to redisplay it via either a help buton (this could, for example, be inside a dat.gui interface) or via a keyboard shortcut (commonly the question mark). -- Your HTML and CSS should validate. There are options/plugins for most IDEs to check validation. - -The interactive experience should possess a reasonable level of complexity. Some examples: -### Three.js -- A generative algorithm creates simple agents that move through a virtual world. Your interface controls the behavior / appearance of these agents. -- A simple 3D game -- An 3D audio visualization of a song of your choosing. User interaction should control aspects of the visualization. -### Canvas -- Implement a generative algorithm such as [Conway's Game of Life](https://bitstorm.org/gameoflife/) (or 1D cellular automata) and provide interactive controls. Note that the Game of Life has been created by 100s of people using ; we'll be checking to ensure that your implementation is not a copy of these. -- Design a 2D audio visualizer of a song of your choosing. User interaction should control visual aspects of the experience. -### Web Audio API -- Create a screen-based musical instrument using the Web Audio API. You can use projects such as [Interface.js](http://charlie-roberts.com/interface/) or [Nexus UI](https://nexus-js.github.io/ui/api/#Piano) to provide common musical interface elements, or use dat.GUI in combination with mouse/touch events (use the Pointer Events API). Your GUI should enable users to control aspects of sound synthesis. -### D3.js -- Create visualizations using the datasets found at [Awesome JSON Datasets](https://github.com/jdorfman/Awesome-JSON-Datasets). Experiment with providing different visualizations of the same data set, and providing users interactive control over visualization parameters and/or data filtering. Alternatively, create a single visualization with using one of the more complicated techniques shown at [d3js.org](d3js.org) and provide meaningful points of interaction for users. - -Deliverables +Author: Abhijay Thammana --- -Do the following to complete this assignment: - -1. Implement your project with the above requirements. -3. Test your project to make sure that when someone goes to your main page on Glitch/Heroku/etc., it displays correctly. -4. Ensure that your project has the proper naming scheme `a4-firstname-lastname` so we can find it. -5. Fork this repository and modify the README to the specifications below. *NOTE: If you don't use Glitch for hosting (where we can see the files) then you must include all project files that you author in your repo for this assignment*. -6.

You can only play alone, because the client code is already a nightmare, so using that with server would've been so much worse. Basically you can select a piece and move it to a square that would be correct in a normal chess game. The 3d files were from sketchfab and made by 'moyicat'. After they were imported the pieces are cloned, placed into the correct places and then based in the selections and inputs they are moved and deleted when necessary. I faced a lot of difficulty learning Three JS because it was my first time using it. Importing 3d images was also kind of hard, but once I got used to it, it wasn't too hard. Finding the material to change the color for black pieces from the clones of the imports was very difficult. But I did find them eventually. And lastly, making all the game logic for the chess pieces was hard and buggy. But eventually I finished that as well. The website is pretty intuitive if you know chess. Just click a piece and then type the square that you would want to move them to. diff --git a/app.js b/app.js new file mode 100644 index 00000000..1367fbef --- /dev/null +++ b/app.js @@ -0,0 +1,10 @@ +const express = require('express'); + +const app = express(); +const port = 3000; + +app.use(express.static("public")); + +app.listen(process.env.PORT || port, () => { + console.log('App listening on port', process.env.PORT || port); +}); \ No newline at end of file diff --git a/node_modules/.bin/mime b/node_modules/.bin/mime new file mode 100644 index 00000000..91e5e16a --- /dev/null +++ b/node_modules/.bin/mime @@ -0,0 +1,15 @@ +#!/bin/sh +basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')") + +case `uname` in + *CYGWIN*|*MINGW*|*MSYS*) basedir=`cygpath -w "$basedir"`;; +esac + +if [ -x "$basedir/node" ]; then + "$basedir/node" "$basedir/../mime/cli.js" "$@" + ret=$? +else + node "$basedir/../mime/cli.js" "$@" + ret=$? +fi +exit $ret diff --git a/node_modules/.bin/mime.cmd b/node_modules/.bin/mime.cmd new file mode 100644 index 00000000..746a2798 --- /dev/null +++ b/node_modules/.bin/mime.cmd @@ -0,0 +1,17 @@ +@ECHO off +SETLOCAL +CALL :find_dp0 + +IF EXIST "%dp0%\node.exe" ( + SET "_prog=%dp0%\node.exe" +) ELSE ( + SET "_prog=node" + SET PATHEXT=%PATHEXT:;.JS;=;% +) + +"%_prog%" "%dp0%\..\mime\cli.js" %* +ENDLOCAL +EXIT /b %errorlevel% +:find_dp0 +SET dp0=%~dp0 +EXIT /b diff --git a/node_modules/.bin/mime.ps1 b/node_modules/.bin/mime.ps1 new file mode 100644 index 00000000..a6f6f470 --- /dev/null +++ b/node_modules/.bin/mime.ps1 @@ -0,0 +1,18 @@ +#!/usr/bin/env pwsh +$basedir=Split-Path $MyInvocation.MyCommand.Definition -Parent + +$exe="" +if ($PSVersionTable.PSVersion -lt "6.0" -or $IsWindows) { + # Fix case when both the Windows and Linux builds of Node + # are installed in the same directory + $exe=".exe" +} +$ret=0 +if (Test-Path "$basedir/node$exe") { + & "$basedir/node$exe" "$basedir/../mime/cli.js" $args + $ret=$LASTEXITCODE +} else { + & "node$exe" "$basedir/../mime/cli.js" $args + $ret=$LASTEXITCODE +} +exit $ret diff --git a/node_modules/accepts/HISTORY.md b/node_modules/accepts/HISTORY.md new file mode 100644 index 00000000..0bf04178 --- /dev/null +++ b/node_modules/accepts/HISTORY.md @@ -0,0 +1,236 @@ +1.3.7 / 2019-04-29 +================== + + * deps: negotiator@0.6.2 + -

All +middlewares will populate the `req.body` property with the parsed body when +the `Content-Type` request header matches the `type` option, or an empty +object (`{}`) if there was no body to parse, the `Content-Type` was not matched, +or an error occurred. + +The various errors returned by this module are described in the +[errors section](#errors). + +### bodyParser.json([options]) + +Returns middleware that only parses `json` and only looks at requests where +the `Content-Type` header matches the `type` option. This parser accepts any +Unicode encoding of the body and supports automatic inflation of `gzip` and +`deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). + +#### Options + +The `json` function takes an optional `options` object that may contain any of +the following keys: + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### reviver + +The `reviver` option is passed directly to `JSON.parse` as the second +argument. You can find more information on this argument +[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter). + +##### strict + +When set to `true`, will only accept arrays and objects; when `false` will +accept anything `JSON.parse` accepts. Defaults to `true`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not a +function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `json`), a mime type (like `application/json`), or +a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a truthy +value. Defaults to `application/json`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.raw([options]) + +Returns middleware that parses all bodies as a `Buffer` and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`).

The parsing can be aborted by throwing an error. + +### bodyParser.text([options]) + +Returns middleware that parses all bodies as a string and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser supports automatic inflation of `gzip` and `deflate` encodings. + +A new `body` string containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This will be a string of the +body. + +#### Options + +The `text` function takes an optional `options` object that may contain any of +the following keys: + +##### defaultCharset + +Specify the default character set for the text content if the charset is not +specified in the `Content-Type` header of the request. Defaults to `utf-8`. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `txt`), a mime type (like `text/plain`), or a mime +type with a wildcard (like `*/*` or `text/*`). If a function, the `type` +option is called as `fn(req)` and the request is parsed if it returns a +truthy value. Defaults to `text/plain`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +### bodyParser.urlencoded([options]) + +Returns middleware that only parses `urlencoded` bodies and only looks at +requests where the `Content-Type` header matches the `type` option. This +parser accepts only UTF-8 encoding of the body and supports automatic +inflation of `gzip` and `deflate` encodings. + +A new `body` object containing the parsed data is populated on the `request` +object after the middleware (i.e. `req.body`). This object will contain +key-value pairs, where the value can be a string or array (when `extended` is +`false`), or any type (when `extended` is `true`). + +#### Options + +The `urlencoded` function takes an optional `options` object that may contain +any of the following keys: + +##### extended + +The `extended` option allows to choose between parsing the URL-encoded data +with the `querystring` library (when `false`) or the `qs` library (when +`true`). The "extended" syntax allows for rich objects and arrays to be +encoded into the URL-encoded format, allowing for a JSON-like experience +with URL-encoded. For more information, please +[see the qs library](https://www.npmjs.org/package/qs#readme). + +Defaults to `true`, but using the default has been deprecated. Please +research into the difference between `qs` and `querystring` and choose the +appropriate setting. + +##### inflate + +When set to `true`, then deflated (compressed) bodies will be inflated; when +`false`, deflated bodies are rejected. Defaults to `true`. + +##### limit + +Controls the maximum request body size. If this is a number, then the value +specifies the number of bytes; if it is a string, the value is passed to the +[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults +to `'100kb'`. + +##### parameterLimit + +The `parameterLimit` option controls the maximum number of parameters that +are allowed in the URL-encoded data. If a request contains more parameters +than this value, a 413 will be returned to the client. Defaults to `1000`. + +##### type + +The `type` option is used to determine what media type the middleware will +parse. This option can be a string, array of strings, or a function. If not +a function, `type` option is passed directly to the +[type-is](https://www.npmjs.org/package/type-is#readme) library and this can +be an extension name (like `urlencoded`), a mime type (like +`application/x-www-form-urlencoded`), or a mime type with a wildcard (like +`*/x-www-form-urlencoded`). If a function, the `type` option is called as +`fn(req)` and the request is parsed if it returns a truthy value. Defaults +to `application/x-www-form-urlencoded`. + +##### verify + +The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, +where `buf` is a `Buffer` of the raw request body and `encoding` is the +encoding of the request. The parsing can be aborted by throwing an error. + +## Errors + +The middlewares provided by this module create errors depending on the error +condition during parsing. The errors will typically have a `status`/`statusCode` +property that contains the suggested HTTP response code, an `expose` property +to determine if the `message` property should be displayed to the client, a +`type` property to determine the type of error without matching against the +`message`, and a `body` property containing the read body, if available. + +The following are the common errors emitted, though any error can come through +for various reasons. + +### content encoding unsupported + +This error will occur when the request had a `Content-Encoding` header that +contained an encoding but the "inflation" option was set to `false`. The +`status` property is set to `415`, the `type` property is set to +`'encoding.unsupported'`, and the `charset` property will be set to the +encoding that is unsupported. + +### request aborted + +This error will occur when the request is aborted by the client before reading +the body has finished. The `received` property will be set to the number of +bytes received before the request was aborted and the `expected` property is +set to the number of expected bytes. The `status` property is set to `400` +and `type` property is set to `'request.aborted'`. + +### request entity too large + +This error will occur when the request body's size is larger than the "limit" +option. The `limit` property will be set to the byte limit and the `length` +property will be set to the request body's length. The `status` property is +set to `413` and the `type` property is set to `'entity.too.large'`. + +### request size did not match content length + +This error will occur when the request's length did not match the length from +the `Content-Length` header. This typically occurs when the request is malformed, +typically when the `Content-Length` header was calculated based on characters +instead of bytes. The `status` property is set to `400` and the `type` property +is set to `'request.size.invalid'`. + +### stream encoding should not be set + +This error will occur when something called the `req.setEncoding` method prior +to this middleware. This module operates directly on bytes only and you cannot +call `req.setEncoding` when using this module. The `status` property is set to +`500` and the `type` property is set to `'stream.encoding.set'`. + +### too many parameters + +This error will occur when the content of the request exceeds the configured +`parameterLimit` for the `urlencoded` parser. The `status` property is set to +`413` and the `type` property is set to `'parameters.too.many'`. + +### unsupported charset "BOGUS" + +This error will occur when the request had a charset parameter in the +`Content-Type` header, but the `iconv-lite` module does not support it OR the +parser does not support it. The charset is contained in the message as well +as in the `charset` property. The `status` property is set to `415`, the +`type` property is set to `'charset.unsupported'`, and the `charset` property +is set to the charset that is unsupported. + +### unsupported content encoding "bogus" + +This error will occur when the request had a `Content-Encoding` header that +contained an unsupported encoding. The encoding is contained in the message +as well as in the `encoding` property. The `status` property is set to `415`, +the `type` property is set to `'encoding.unsupported'`, and the `encoding` +property is set to the encoding that is unsupported. + +## Examples + +### Express/Connect top-level generic + +This example demonstrates adding a generic JSON and URL-encoded parser as a +top-level middleware, which will parse the bodies of all incoming requests. +This is the simplest setup. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse application/x-www-form-urlencoded +app.use(bodyParser.urlencoded({ extended: false })) + +// parse application/json +app.use(bodyParser.json()) + +app.use(function (req, res) { + res.setHeader('Content-Type', 'text/plain') + res.write('you posted:\n') + res.end(JSON.stringify(req.body, null, 2)) +}) +``` + +### Express route-specific + +This example demonstrates adding body parsers specifically to the routes that +need them. In general, this is the most recommended way to use body-parser with +Express. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// create application/json parser +var jsonParser = bodyParser.json() + +// create application/x-www-form-urlencoded parser +var urlencodedParser = bodyParser.urlencoded({ extended: false }) + +// POST /login gets urlencoded bodies +app.post('/login', urlencodedParser, function (req, res) { + res.send('welcome, ' + req.body.username) +}) + +// POST /api/users gets JSON bodies +app.post('/api/users', jsonParser, function (req, res) { + // create user in req.body +}) +``` + +### Change accepted type for parsers + +All the parsers accept a `type` option which allows you to change the +`Content-Type` that the middleware will parse. + +```js +var express = require('express') +var bodyParser = require('body-parser') + +var app = express() + +// parse various different custom JSON types as JSON +app.use(bodyParser.json({ type: 'application/*+json' })) + +// parse some custom thing into a Buffer +app.use(bodyParser.raw({ type: 'application/vnd.custom-type' })) + +// parse an HTML body into a string +app.use(bodyParser.text({ type: 'text/html' })) +``` + +## License + +[MIT](LICENSE) + +[npm-image]: https://img.shields.io/npm/v/body-parser.svg +[npm-url]:

require('cookie'); +``` + +### cookie.parse(str, options) + +Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs. +The `str` argument is the string representing a `Cookie` header value and `options` is an +optional object containing additional parsing options. + +```js +var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2'); +// { foo: 'bar', equation: 'E=mc^2' } +``` + +#### Options + +`cookie.parse` accepts these properties in the options object. + +##### decode + +Specifies a function that will be used to decode a cookie's value. Since the value of a cookie +has a limited character set (and must be a simple string), this function can be used to decode +a previously-encoded cookie value into a JavaScript string or other object. + +The default function is the global `decodeURIComponent`, which will decode any URL-encoded +sequences into their byte representations. + +**note** if an error is thrown from this function, the original, non-decoded cookie value will +be returned as the cookie's value. + +### cookie.serialize(name, value, options) + +Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the +name for the cookie, the `value` argument is the value to set the cookie to, and the `options` +argument is an optional object containing additional serialization options. + +```js +var setCookie = cookie.serialize('foo', 'bar'); +// foo=bar +``` + +#### Options + +`cookie.serialize` accepts these properties in the options object. + +##### domain + +Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no +domain is set, and most clients will consider the cookie to apply to only the current domain. + +##### encode + +Specifies a function that will be used to encode a cookie's value. Since value of a cookie +has a limited character set (and must be a simple string), this function can be used to encode +a value into a string suited for a cookie's value. + +The default function is the global `encodeURIComponent`, which will encode a JavaScript string +into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range. + +##### expires + +Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1]. +By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and +will delete it on a condition like exiting a web browser application. + +**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and +`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### httpOnly + +Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy, +the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not allow client-side +JavaScript to see the cookie in `document.cookie`. + +##### maxAge + +Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2]. +The given number will be converted to an integer by rounding down. By default, no maximum age is set. + +**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and +`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this, +so if both are set, they should point to the same date and time. + +##### path + +Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path +is considered the ["default path"][rfc-6265-5.1.4]. + +##### sameSite + +Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-03-4.1.2.7]. + + - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + - `false` will not set the `SameSite` attribute. + - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement. + - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie. + - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement. + +More information about the different enforcement levels can be found in +[the specification][rfc-6265bis-03-4.1.2.7]. + +**note** This is an attribute that has not yet been fully standardized, and may change in the future. +This also means many clients may ignore this attribute until they understand it. + +##### secure + +Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy, +the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set. + +**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to +the server in the future if the browser does not have an HTTPS connection. + +## Example + +The following example uses this module in conjunction with the Node.js core HTTP server +to prompt a user for their name and display it back on future visits. + +```js +var cookie = require('cookie'); +var escapeHtml = require('escape-html'); +var http = require('http'); +var url = require('url'); + +function onRequest(req, res) { + // Parse the query string + var query = url.parse(req.url, true, true).query; + + if (query && query.name) { + // Set a new cookie with the name + res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), { + httpOnly: true, + maxAge: 60 * 60 * 24 * 7 // 1 week + })); + + // Redirect back after setting cookie + res.statusCode = 302; + res.setHeader('Location', req.headers.referer || '/'); + res.end(); + return; + } + + // Parse the cookies on the request + var cookies = cookie.parse(req.headers.cookie || ''); + + // Get the visitor name set in the cookie + var name = cookies.name; + + res.setHeader('Content-Type', 'text/html; charset=UTF-8'); + + if (name) { + res.write('
