Description

This PR resolves #380 by extracting the Koffi-based native input injection layer into a separate, reusable npm package: @aossie/rein-input located under packages/rein-input.

This decouples the low-level OS input injection logic from the Rein server and allows consumers across the ecosystem to easily integrate, version, and reuse cross-platform mouse, keyboard, touch, and gesture injection.


Key Changes

  • Standalone Package (packages/rein-input):
    • Encapsulated drivers for Linux (uinput), macOS (CoreGraphics), and Windows (SendInput + Synthetic Pointer API).
    • Added high-level createInputInjector() factory that automatically instantiates the appropriate platform driver with safe stub fallback on unsupported systems.
    • Setup dual-module build (dist/index.js for ESM and dist/index.cjs for CJS) alongside TypeScript declarations (.d.ts).
  • Application Integration:
    • Configured npm workspaces ("workspaces": ["packages/*"]) in root package.json.
    • Refactored src/server/InputHandler.ts to consume @aossie/rein-input.
    • Added src/server/drivers/index.ts re-export bridge to ensure 100% backward compatibility for existing code.
  • Unit Testing Suite:
    • Added test suite in packages/rein-input/test/ covering applyMotion, resolveChar, keymaps (VK_MAP, LINUX_KEY_MAP, MAC_KEY_MAP), factory instantiation, and platform guards.
  • CI/CD Workflow:
    • Added .github/workflows/package.yml with multi-OS matrix testing (Ubuntu, macOS, Windows) and automated npm publishing on release.
    • Updated .github/workflows/ci.yml to run tests and package builds during PR validation.
  • Documentation:
    • Added comprehensive packages/rein-input/README.md with quick-start guides, multitouch examples, API documentation, and platform permissions setup.

Verification

  • npm run test passes (4 test files, 22 unit tests passing).
  • npm run check (Biome linting & formatting) passes with 0 errors.
  • npm run typecheck (TypeScript strict mode) passes with 0 errors.
  • npm run build:package successfully bundles ESM, CJS, and .d.ts outputs.
  • npm pack --dry-run validates correct tarball contents.
  • npm run build succeeds for the main Rein application.

Closes #380

Summary by CodeRabbit

  • New Features
    • Added the reusable @aossie/rein-input package for mouse, keyboard, text, wheel, and multitouch input across Windows, Linux, and macOS.

Merge Risk: 🟠 High · up to 69cc2

This PR moves cross-platform input injection into a published package and changes the server integration, but the current version can mis-handle native input, leave host controls pressed or leak resources during teardown, and publish an unusable package from a clean checkout. Release automation and permission guidance also need tightening, so it is not merge-ready until these issues are fixed or explicitly accepted.

Pull request overview

This PR extracts Rein’s native (Koffi-based) cross-platform input injection layer into a reusable workspace package, @aossie/rein-input (packages/rein-input), then updates the Rein server to consume it while keeping a backward-compatible re-export bridge under src/server/drivers/. It also extends CI to test/build the package and introduces a new UI consent gate before initiating WebRTC screen share on the trackpad route.

Changes:

  • Added packages/rein-input npm library (drivers, factory, keymaps, utilities) plus a Vitest unit test suite and package build script.
  • Refactored server input injection usage to consume @aossie/rein-input, and added tooling/workspace wiring (TS paths, Vitest include, Biome include, root workspaces/scripts).
  • Added a “Screen Share Consent” overlay to gate connection initiation on /trackpad, plus i18n strings and documentation updates.

  • _CGEventSetIntegerValueField is declared as a const null and never initialized, but postMediaKeyEvent() requires it. As a result, postMediaKeyEvent() will always early-return and media key injection will never work.

Inline comments:
In @.github/workflows/package.yml:
- Around line 8-14: Update the paths filters for both push and pull_request in
the workflow to include package.json, tsconfig.json, vitest.config.ts, and the
active root lockfile, ensuring root tooling changes trigger the package
validation workflow.
- Around line 35-42: Update the actions/checkout and actions/setup-node
references in the workflow to immutable full commit SHAs instead of mutable
version tags, and configure the repository’s automated dependency update tooling
to maintain these action pins.
- Around line 25-36: Update the test-package job to explicitly grant only
contents: read permission, and set persist-credentials to false on both checkout
steps used by the workflow. Leave the publish job’s id-token: write permission
unchanged for npm provenance.
- Around line 53-56: Update the “Verify Package Tarball” workflow step to create
the actual npm tarball, install it in a clean temporary consumer project, and
smoke-test both the declared ESM and CommonJS entry points on every matrix
operating system before publishing; replace the dry-run-only verification while
preserving the package scope.

In `@packages/rein-input/package.json`:
- Around line 52-56: Add a package lifecycle script alongside the existing
build, typecheck, and test scripts that invokes the build before publishing or
packing, ensuring the dist output is generated on clean releases before files
are included.
- Around line 57-67: Update the package manifest so koffi remains only as a
required peer dependency, remove its peerDependenciesMeta entry, and add koffi
to devDependencies for local builds and tests; do not retain it in dependencies.

In `@packages/rein-input/README.md`:
- Around line 21-28: Update the “Full Input Capabilities” documentation to avoid
claiming arbitrary Unicode text injection on Linux; describe support as limited
to characters represented by the Linux keyboard maps, including LINUX_KEY_MAP
and SHIFTED_CHARS, unless LinuxKeyboard.injectText gains Unicode input handling.
- Around line 189-194: Update the Linux setup instructions in the README to
avoid the broad input group: create and use a package-specific group for
/dev/uinput, assign only that device to the new group in the udev rule, and add
the user to that group instead of input.

In `@packages/rein-input/src/factory.ts`:
- Around line 84-89: Update the options discriminator in createInputInjector to
detect wrapper keys config, platform, or onError rather than selected
InputConfig fields, preserving every direct InputConfig property; update
packages/rein-input/src/factory.ts lines 84-89 accordingly. Add acceleration and
screenHeight cases to packages/rein-input/test/factory.test.ts lines 58-64 and
assert the selected injector receives each supplied direct configuration.

In `@packages/rein-input/src/keyMap.ts`:
- Around line 281-290: Add the missing "0" entry with value 0x1d to MAC_KEY_MAP
so MacKeyboard.injectKey("0", "HOLD") uses the macOS key mapping, and add a
regression assertion in the existing keyMap tests covering this behavior.

In `@packages/rein-input/src/linux/index.ts`:
- Around line 173-183: Update injectMouseMove to use the package motion helper
so configured sensitivity and acceleration are applied. In updateConfig, detect
screen-bound changes and reconfigure or recreate the touch device so native
absolute-axis ranges stay synchronized; otherwise reject runtime configuration
fields that cannot be applied safely.

In `@packages/rein-input/src/linux/keyboard.ts`:
- Around line 31-41: Update injectCombo so it returns immediately when any key
is missing from LINUX_KEY_MAP, rather than skipping unknown keys and continuing.
Preserve the warning for the unknown key and ensure no events are emitted for an
incomplete combo.

In `@packages/rein-input/src/linux/structs.ts`:
- Around line 29-34: Correct the Linux uinput ABI in UinputAbsSetup by removing
the extra padding so absinfo starts at byte offset 4 and the structure is 28
bytes; also update UI_ABS_SETUP in packages/rein-input/src/linux/constants.ts
lines 50-53 to encode the 28-byte payload as 0x401c5504.

In `@packages/rein-input/src/mac/index.ts`:
- Around line 71-98: Update injectMouseMove to read the current cursor location
via CGEventGetLocation(CGEventCreate(null)) before applying dx and dy,
resynchronizing cursorX and cursorY with the physical pointer. Clamp the
resulting coordinates to screenWidth - 1 and screenHeight - 1, while preserving
the existing event-type and button-selection behavior.

In `@packages/rein-input/src/mac/keyboard.ts`:
- Around line 12-18: Remove the audiostop entry from MEDIA_KEY_MAP so audiostop
is treated as unsupported rather than mapped to NX_KEYTYPE_PLAY; leave the other
media-key mappings unchanged.

In `@packages/rein-input/src/mac/touch.ts`:
- Around line 79-92: Update processMoves to ignore contacts whose activeContacts
lookup returns no previous entry: continue without handling or inserting those
untracked moves. Preserve existing drag and two-finger handling only for tracked
contacts, and keep updating activeContacts for valid tracked moves.

In `@packages/rein-input/src/types.ts`:
- Around line 35-51: Update the public types near PlatformInjector so
injectKey’s optional pos parameter accepts only the supported "HOLD" and
"RELEASE" values, and change InputMessage.button to reuse MouseButton instead of
duplicating its union. Keep all other input contracts unchanged and use explicit
TypeScript types.

In `@packages/rein-input/src/utils.ts`:
- Around line 18-23: The acceleration logic in the magnitude calculation must be
continuous and non-decreasing at ACCEL_THRESHOLD: ensure the accelerated
magnitude equals the raw magnitude at the threshold and grows for larger
magnitudes, while preserving the existing below-threshold behavior. Update the
curve implementation near ACCEL_EXPONENT and ACCEL_FACTOR, and add regression
coverage for magnitudes below, exactly at, and above ACCEL_THRESHOLD.

In `@packages/rein-input/src/windows/constants.ts`:
- Line 27: Update the synthetic pointer-device initialization to use
CreateSyntheticPointerDevice2 for PT_TOUCHPAD, passing
SYNTHETIC_DEVICE_CREATION_PARAMS with POINTER_FEEDBACK_NONE (3), the required
physical dimensions, and appropriate options. Rename POINTER_FEEDBACK_DEFAULT to
reflect the POINTER_FEEDBACK_NONE value and update all references accordingly.

In `@packages/rein-input/src/windows/index.ts`:
- Around line 156-158: Update WindowsInputInjector to track buttons pressed via
injectMouseButton and keys held via injectKey, then release all tracked inputs
in destroy() before or alongside tearing down touch state; preserve normal
press/release behavior and match MacInputInjector’s cleanup contract.
- Around line 95-133: In injectMouseWheel, convert each rounded vertical and
horizontal mouseData value to uint32 with an unsigned conversion before
assigning it, while retaining the DWORD declaration. Also remove the horizontal
direction negation so positive dx follows the documented Win32 and
other-platform behavior unless the input protocol explicitly defines it as left.

In `@packages/rein-input/src/windows/keyboard.ts`:
- Around line 90-121: Update injectText to iterate over the input string’s
UTF-16 code units rather than code points, ensuring each unit is converted with
charCodeAt and sent as its own KEYEVENTF_UNICODE key-down/up pair through
sendInput. Preserve the existing event structure and ordering.

In `@packages/rein-input/src/windows/structs.ts`:
- Around line 72-76: Remove the hard-coded __pad field from the INPUT koffi
struct and from all INPUT event objects, allowing platform-native alignment to
determine the union offset and struct size. Ensure INPUT_STRUCT_SIZE and
SendInput use the corrected INPUT layout; alternatively, add an explicit 32-bit
Node architecture rejection with a matching package constraint.

In `@packages/rein-input/src/windows/touch.ts`:
- Around line 176-194: Add a DestroySyntheticPointerDevice binding in
structs.ts, initialized through ensureLib and exposed as a safe wrapper for
non-null handles. In the touch device destroy() method, release active contacts
first, then call DestroySyntheticPointerDevice(this.hDevice) before clearing the
handle and resetting state.
- Around line 54-65: Update getOrAllocPointerId to handle pointer-ID exhaustion
by logging the existing warning and returning a sentinel that lets the contact
loop skip the extra contact, rather than throwing. Update injectTouch to ignore
that contact without adding it to the frame, while preserving allocation and
contactIdMap behavior for contacts with available IDs.

In `@packages/rein-input/test/platform-injectors.test.ts`:
- Around line 6-30: Expand the platform injector tests beyond
unsupported-platform constructor guards by mocking each platform’s native
bindings and device setup, then assert mouse and keyboard injection,
touch-release handling, native-call failures, and destroy() behavior for
LinuxInputInjector, MacInputInjector, and WindowsInputInjector. Ensure
matching-host tests always execute assertions and cover the relevant success and
error paths deterministically.

In `@README.md`:
- Around line 27-30: Insert a blank line between the rein-input package
description and its fenced npm installation block in the README list item,
preserving the existing code block content.

In `@src/components/Trackpad/ScreenShareConsent.tsx`:
- Around line 15-16: Update the ScreenShareConsent dialog root with dialog
semantics and accessible labeling, announce changes to the denied state, and use
React refs/effects to focus the primary action when the dialog opens and again
after Deny removes the secondary button. Apply aria-modal="true" only once the
surrounding route has made the rest of the trackpad inert.

In `@src/server/drivers/mac/structs.ts`:
- Line 26: Update _CGEventSetIntegerValueField to be mutable and bind it to
CGEventSetIntegerValueField within ensureMediaFunctions, so postMediaKeyEvent
can proceed with media-event posting instead of returning due to a null binding.

In `@src/utils/logger.ts`:
- Around line 61-62: Update serialize to never throw for any unknown value:
safely handle circular structures and bigint values, preserve useful details
from Error instances, and ensure undefined or any failed/empty JSON
serialization produces a safe string fallback suitable for console.error.

Hi @Aryan-en, nice work extracting this into a reusable package. I took a look at the failing CI and reproduced the build failures locally on your branch. Two things stand out:

npm ci fails on Windows — the package-lock.json is out of sync (missing typescript and lru-cache entries), so CI's clean install bails before it can build.
vite build fails on Ubuntu/macOS — @aossie/rein-input's dist/ isn't built before the root build runs, so Vite can't resolve the package entry on a fresh checkout.

I'd be happy to help sort these out if you haven't already got a fix in progress. Would you prefer I open a PR against your fork with the changes, or would you rather take them yourself? Just let me know so we don't duplicate effort. @Aryan-en

Hi maintainers — I wanted to coordinate on Discord per CONTRIBUTING.md, but both invite links I could find are expired (README/CONTRIBUTING points to discord.com/invite/C8wHmwtczs → "Invite Invalid", and the Gitcord bot's discord.gg/hjUhu33uAn also doesn't work). Could someone share a current invite? Worth updating the docs too, since it blocks new contributors.

In the meantime: I've been looking at the failing Build Electron jobs on this PR and found + verified a fix. The build.yml workflow runs npm run build (which is just vite build) without building the package first, so packages/rein-input/dist/ doesn't exist on a clean checkout and Vite can't resolve the @aossie/rein-input entry — that's the ubuntu/macos failure. Chaining build:package before vite build fixes it (verified locally, clean build passes end to end). The Windows npm ci lockfile error looks already resolved on the latest commit — a clean npm ci passes for me now.

Happy to open a PR to @Aryan-en's fork with the one-line fix, or coordinate however you'd prefer. Just didn't want to duplicate work.

Opened #387 against @Aryan-en branch with a fix for the failing Build Electron jobs — the build.yml workflow runs npm run build without building the package first, so packages/rein-input/dist/ doesn't exist on a clean checkout and Vite can't resolve the entry. Chaining build:package before vite build fixes ubuntu/macos (verified locally). Once it's merged into this branch these checks should go green. @Aryan-en Bro sent you a request in discord check it out
