ts-webpack

It's always time consuming to combine all components together and make things work well.

This project template helps you create a whole new project with out-of-the-box features including typescript, webpack, babel settings and so on...

Just clone this repository to your disk, you can start coding from the entry.ts without worring anything about config files.

Install Tools

sudo npm install typescript -g
sudo npm install typings -g
sudo npm install webpack -g
sudo npm install webpack-dev-server -g

Build

Install the dependencies

sudo npm link typescript
npm install
typings install

Run webpack to build the files

webpack

Run webpack-dev-server:

webpack-dev-server

Guide

The Current Setup

tsconfig: target is set to "es5", so you don't have to convert es6 classes with babel, this makes browsers comfortable with the compiled files. if you want to develop node js modules, then setting target to es6 should just fine.

webpack: right now the config separates .ts, .js loaders, so you don't have to pipe tsc output to babel loader, which is slower. If you really want your tsc es6 output to be compiled into es5. use webpack.config.es6-to-es5.js config instead.

Rename all files from .js to .ts

Get fsrename

go get -u -x github.com/c9s/fsrename/fsrename

Rename files:

fsrename -replace .js -with .ts src/

Modify your webpack target entry name

vim webpack.config.js

Change

module.exports = {
    'entry': {
        'myproj': ['./entry'],
    }
}

To whatever you want.

Start Coding

Just start coding from entry.ts and src/... without worring anything!

Get Your Type Definition Files

Sample commands:

typings install dt~d3 --save --global
typings install dt~jquery --save --global
typings install dt~mocha --save --global

Generate typedoc

typedoc --target es6 --out doc typings/index.d.ts src

ts-loader + babel-loader is too slow!?

You can simply change the target from es6 to es5 in tsconfig.json and remove the babel-loader from webpack.config.js.

Advanced babelrc Config File

.babelrc

{
    "presets": ["es2015", "es2015-native-modules"],
    "plugins": [
        "transform-runtime",
        [
        "transform-es2015-modules-commonjs", {
            "strict": false,
            "loose": true
        }],
        "babel-plugin-transform-object-assign"
    ]
}

Trouble Shooting

Cannot find module '...'

For example, you encountered this error message:

Cannot find module 'object-assign'

Simply run:

npm install object-assign --save
typings install object-assign --save

Then re-compile, it should work.

FAQ

Why use `import assign = require("object-assign");` instead of es6 import?

This is because TypeScript can't properly loads node modules with es6 import syntax with non-default export modules. for example:

import assign from "object-assign";
assign({}, ...);

The assign call above will be converted to:

assign.default({}, ...);

However object-assign doesn't export "exports.default", this causes error in the runtime.

With the suggested es6 import statement:

import * as assign from "object-assign";
assign({}, ...);

Occurs error like:

error TS2497: Module ''object-assign'' resolves to a non-module entity and
cannot be imported using this construct.

This is because object-assign exports the function using module.exports = {function}.

module.exports = shouldUseNative() ? Object.assign : function (target, source) {
