midway tsc

it's a tsc wrapper, like tsc-watch.

Usage

# run package file
$ npx mwtsc --watch --run @midwayjs/mock/app.js

# run file
$ npx mwtsc --watch --run ./bootstrap.js

# run with tsc options
$ npx mwtsc --watch --project tsconfig.production.json --run ./bootstrap.js

# the child process keep avaliable during the development
$ npx mwtsc --watch --run ./bootstrap.js --keepalive

Different with tsc and tsc-watch

• 1、support --run option, run file after compile success
• 2、support copy non-ts file to dist directory when build source code
• 3、support ts alias path by tsc-alias

API

You can use mwtsc API in your code to extend your own logic.

mwtsc API:

• run - run tsc compile
• chokidar - watch file change

run API:

• exit - exit process
• restart - restart process
• onExit - on exit event

// custom.js
const { run, chokidar } = require('mwtsc');
const { restart, exit, onExit } = run();

const watcher = chokidar.watch('node_modules/**/*.ts', {
  ignoreInitial: true,
  ignored: ['**/*.d.ts'],
});

watcher.on('all', (event, path) => {
  console.log(event, path);
  restart([
    '/home/admin/workspace/midwayjs/midway/packages/mock/src/app.ts',
  ]);
});

onExit(async () => {
  await watcher.close();
});

Rewrite dev command in package.json .

{
  "scripts": {
    "dev": "NODE_ENV=local node ./custom.js --watch --run ./bootstrap.js"
  }
}
