If you want to use typescript
with babel-node
, here is how you do it:
install dependencies
npm i -D @babel/core @babel/node @babel/preset-env @babel/preset-typescript typescript
setup npm script
"scripts": {
"start": "babel-node -x .ts -- src/app.ts",
}
create a babel.config.js
module.exports = {
presets: [
'@babel/preset-typescript',
[
'@babel/preset-env',
{
targets: {
node: 'current',
},
},
],
],
}
create a src/app.ts
, in this example I use koa
import Koa from 'koa'
const app = new Koa()
// response
app.use(ctx => {
ctx.body = 'Hello Koa'
})
app.listen(3000)
finally npm start
and boom, it just works.
This solution comes in handy when you are tight on memory and you want to avoid ts-node
