[Proposal] JavaScript IR Module Implementation

Proposal: Infrared JavaScript Module for Flipper Zero

Following up on #4322 — I'd like to propose implementing the JavaScript Infrared module and would be willing to contribute a PR.

Scope:

• infrared JS module wrapping the existing C IR API
• Send raw signals (timings array + frequency)
• Send protocol-based commands (NEC, Samsung, RC5, RC6, etc.)
• Send commands from saved .ir files by name
• Optional: receive with timeout (polling-based)

Implementation Plan:

1. Create js_infrared.c following the pattern in js_gpio.c / js_serial.c
2. Register module in the JS engine plugin system
3. Expose infrared_send_raw(), infrared_send() from the C API
4. Add .ir file parser for named command lookup
5. Write documentation + example scripts

API Design:

let ir = require('infrared');

// Protocol-based
ir.send('NEC', 0x04, 0x08);

// From file
ir.sendFile('/ext/infrared/tv.ir', 'Power');

// Raw timings
ir.sendRaw([9000, 4500, 560, 560], 38000);

Happy to discuss the approach or adapt to the team's preferred architecture.

+1. I just ran into this for a personal fun project.

My use case is simple: I recorded a bunch of lego remote commands to Lego_1.ir file. I downloaded the file, so I can re-format commands any way needed (i.e. Claude can). I want to make a simple JS script to play them back with custom UI. I would probably prefer to simply embed the commands into the JS file, so it doesn't depend on any other files. Example script attached.
