tsrun

This is the WebHare wrapper around esbuild which maintains a cache of compiled files.

Setup

To get started:

npm install @webhare/tsrun@latest
echo 'console.log(42 as number);' > test.ts
./node_modules/.bin/tsrun test.ts

Note that tsrun doesn't do any TypeScript validation. For that you will still need to set up the TypeScript compiler and you will need a tsconfig.json in its root, eg:

{
  "extends": "@tsconfig/recommended",
  "compilerOptions": {
    "baseUrl": ".",
    "noEmit": true,
    "target": "es2022",
    "isolatedModules": true
  }
}

The option "isolatedModules": true improves compatibility with esbuild

Compiled TS files are cached in $HOME/.tsrun-cache.

To debug tsrun set the environment variable ESBUILDRUNNER to debug.

WebHare integration

WebHare does not directly use or supply tsrun but builds a slightly different version of this plugin with the following changes:

• tsrun is integratedd into wh run
• You need to set WEBHARE_DEBUG=runner instead of ESBUILDRUNNER=debug to debug
• Compiled TS files are cached inside the whdata folder in ephemeral/compilecache/typescript (use wh dirs and look for WEBHARE_TSBUILDCACHE to get the exact folder)
