lw-ffmpeg-bun

Intro

The 854 byte GZIpped library wrapper around ffmpeg.

import FFMPEGManipulator from "lw-ffmpeg-bun";

Setup

Have a folder structure where all typescript is inside a src folder, and application entrypoint is in src/index.ts.

1. Create a build script that appropiately compiles the src/index.ts file into a dist folder. Make sure you target bun, else it will not work.

   bun build --target=bun --outdir dist src/index.ts

2. Install a .d.ts generator library with bun add --save-dev dts-bundle-generator with bun add -D dts-bundle-generator. Go here for more info: dts bundle generator github

   dts-bundle-generator --out-file dist/index.d.ts src/index.ts

3. Create the build script in the package json

   {
     "scripts": {
       "build": "bun build --minify --target=bun --outdir dist src/index.ts && bun run compile-declaration",
       "compile-declaration": "dts-bundle-generator --out-file dist/index.d.ts src/index.ts"
     }
   }

4. Set tsconfig:

   {
     "compilerOptions": {
       "lib": ["ESNext"],
       "target": "ESNext", // necessary
       "module": "ESNext", // necessary for import.meta.env to work
       "declaration": true, // outputs .d.ts files
       "outDir": "./dist",
       "strict": true,
       "esModuleInterop": true,
       "moduleResolution": "Node", // necessary for no errors
       "skipLibCheck": true
     },
     "include": ["src/index.ts"], // compile entrypoint
     "exclude": ["node_modules", "dist"]
   }

5. Set package json, point to entry points and type declarations

   {
     "name": "lw-ffmpeg-bun",
     "main": "dist/index.js",
     "module": "dist/index.js",
     "files": ["dist"],
     "type": "module",
     "types": "dist/index.d.ts",
     "devDependencies": {
       "@types/bun": "latest",
       "dts-bundle-generator": "^9.5.1"
     },
     "peerDependencies": {
       "typescript": "^5.0.0"
     },
     "scripts": {
       "build": "bun build --minify --target=bun --outdir dist src/index.ts && bun run compile-declaration && cp src/info.bun.sh dist",
       "compile-declaration": "dts-bundle-generator --out-file dist/index.d.ts --project ./tsconfig.json --no-check src/index.ts"
     },
