TypeScript + Babel execution environment and REPL for node
npm install ts-babel-nodeThis package enables Babel compilation of TypeScript compilation output through a registration function and a Node binary proxy.
Because you want ts-node to run async/await code, but TypeScript will only compile async/await to ES6 and Node 5.x doesn't support all of ES6 yet. So you need Babel to bridge that gap.
ts-babel-node wraps ts-node so you can do just that. Run the ts-babel-node executable exactly the same way you'd run ts-node and require ts-babel-node/register instead of ts-node/register.
To use ts-babel-node on the command line, install this package globally. Be sure to include whichever version of TypeScript you want to compile against.
``
$ npm install --global ts-babel-node typescript@1.8
$ ts-babel-node my-file.ts
`
To include ts-babel-node as a register function, install this package as a development dependency. Be sure to include whichever version of TypeScript you want to compile against.
``
$ npm install --save-dev ts-babel-node typescript@1.8
Since ts-babel-node is a wrapper around ts-node, anything you can do with ts-node works with ts-babel-node. See ts-node's docs for more details.
ts-babel-node exposes two APIs. The first is a wrapper around the ts-node API.
`js
// $ node this-file.js
require('ts-babel-node').register(/ ts-node options /);
// Or
require('ts-babel-node/register');
`
You can also use this with the --require option on node.
``
$ node --require ts-babel-node/register my-file.ts
The second API only adds the babel-compilation step. This is useful if your code is run from ts-node, as is the case in the gulp scenario.
`js
// $ ts-node this-file.js
require('ts-babel-node').registerBabel();
// Or
require('ts-babel-node/register-babel');
`
``
$ mocha --require ts-babel-node/register [...args]
``
$ ts-babel-node node_modules/.bin/tape [...args]
In your gulpfile.ts (note, .ts, not .js):
``
import 'ts-babel-node/register-babel';
// ...
Then use gulp normally. Keep in mind that the babel traspiler won't be active in your gulpfile.ts`, but will be running in all your imports.
