An ES Module based library for Node.js and browsers for doing (quadratic and cubic) Bezier curve work.
For a Demo and the API, hit up either pomax.github.io/bezierjs or read the souce (./src for the library code, start at bezier.js).
Note: if you're looking for the legacy ES5 version of this library, you will have to install v2.6.1 or below. However, be aware that the ES5 version will not have any fixes/updates back-ported.
npm install bezier-js will add bezier.js to your dependencies, remember to add --save or --save-dev if you need that to be persistent of course.
There is a rolled-up version of bezier.js in the dist directory. Just download that and drop it in your JS asset dir.
About as simple as it gets:
import { Bezier } from "bezier-js";
const b = new Bezier(...);
Or, using the legacy CommonJS syntax:
const Bezier = require("bezier-js");
const b = new Bezier(...);
| Node Version | Require Supported | Import Supported |
|---|---|---|
| v12.0.0 | Yes | Yes Experimental Flag |
| v12.14.1 | Yes | No Experimental Flag |
| v12.17.0 | Yes | Yes Experimental Warning |
| v12.22.1 | Yes | Yes |
| v14.0.0 | Yes | Yes |
| v14.16.1 | Yes | Yes |
Copy the contents of the src directory to wherever you like (/js, /vendor, etc), or place the rolled-up version of the library there, and then load the library as an import to whatever script needs to use the Bezier constructor using:
import { Bezier } from "/js/vendor/bezier.js";
const b = new Bezier(...);
All the code is in the src directory, with bezier.js as entry point.
To test code (which automatically applies code formatting and rollup), use npm test.
There is no explicit build step for the library, npm test takes care of everything, except checking for code coverage.
