@terse/webpack

Webpack simplified in a fluent API with presets & an escape hatch so you're not locked in.

---

Why?

• Webpack is powerful, but extremely complicated for newcomers to use.
• Merging configuration objects is exceedingly difficult and error-prone.
• Using Webpack on both the server & client is necessary once you leverage Webpack's APIs (e.g. require.context, require.ensure).
• There are tons of configuration pitfalls that can negatively impact your build that you shouldn't have to know about.
• It's a full-time job keeping up-to-date with the latest build optimizations.
• Most React boilerplates have similar configuration, but no abstraction for composition.

Why Not?

• You're comfortable with Webpack configuration.
• You consider abstraction bad (e.g. "magic" or "indirection").
• You have to get access to the "bare-metal" APIs.
• TODO - Check Twitter for more cynical responses.

How?

This project attempts to solve these problems via:

• Built on Webpack2, with the latest advancements.
• Simple, fluent API that takes the guess-work out.
• Escape hatch to copy/paste the generated, raw config.
• Optional .presets for getting started quickly.
• Functional reducers that you can override to customize the output.
• Each action creates a new config, so you can easily compose them.

Upcoming features:

• .presets:
  • .autoinstall() - Install missing dependencies.
  • .conventions() - Default input & output sources.
  • .hot() - Simplify HMR.
  • .offline() - Add offline support to your app.
  • .react() - Quickly get started with React.
• terse-webpack CLI - Start coding without any initialization.
• GUI - Get started on a new project with a few clicks.

Example

// webpack.config.js
module.exports = require("@terse/webpack").api()
  .entry("./src/client.js")
  .loader("babel", ".js", {
    exclude: /node_modules/,
    query: { cacheDirectory: true },
  })
  .modules("./lib")
  .output("build/client")
  .target("web")
  .when("development", function(api) {
    return api
      .entry({
        client: [
          "webpack-hot-middleware/client?reload=true&timeout=2000",
          "./src/client.js",
        ],
      })
      .plugin("npm-install-webpack-plugin")
      .plugin("webpack.HotModuleReplacementPlugin")
      .plugin("webpack.NoErrorsPlugin")
      .sourcemap("source-map")
    ;
  })
  .getConfig()
;

1. Generates client.js in the build directory from ./src/client.js.
2. Parses .js files (excluding node_modules) with Babel.
3. Searches node_modules and ./lib for non-relative files.
4. Outputs assets to ./build/client.
5. Target platform is web (vs. node).
6. When NODE_ENV is development: a. Override client.js to support HMR. b. Add npm-install-webpack-plugin to auto-install missing dependencies. c. Add HMR support. d. Enable source-map-style source maps (e.g. .map files).

Dependencies

I recommend using this against the latest Node + NPM v3.

• Node
• nvm

Installation

npm install @terse/webpack

Usage

View the example.

Replace the contents of webpack.config.js (and others) with:

module.exports = require("@terse/webpack").api()
  ...
  .getConfig()
;

It's crucial to call .getConfig() to return the Webpack configuration.

With the upcoming .presets, it'll be as simple as:

module.exports = require("@terse.webpack").api()
  .presets("autoinstall", "hot", "react", "offline")
  .target("web")
  .getConfig()
;

API

• .api([customFeatures[, customReducers]])

  Begins fluent interface, optionally accepted an array of custom features and custom reducers.

• .alias(name[, pathOrName])

  Maps a package name (e.g. react) to another library (e.g. react-lite) or to a path (e.g. ./node_modules/react).

• .context(path)

  Config files are relative to this folder. (Default: process.cwd())

• .env(environment)

  Overrides NODE_ENV (defaults to development) the build is for.

• .externals(...[Function, RegExp, String])

  Prevents Webpack from bundling matching resources.

• .loader(name[, extensions = ".js"[, options]])

  Add a loader for the given extension(s) with the given settings.

• .modules(path)

  Lookup non-relative (e.g. my-cool-lib) modules in this folder as well as node_modules.

• .node(options)

  Override built-in Node constants & libs (e.g. __dirname, __filename)

• .output(pathOrOptions)

  Set the output path, or specify the entire Webpack output configuration.

• .plugin(name, ...args)

  Installed automatically with the given arguments.

• .preLoader(name[, extensions = ".js"[, options]])

  Just like .loader, but is ran before all other loaders.

• .sourcemap(type)

  Add a source map to the build.

• .target(runtime)

  Either node or web.

• .getConfig()

  Returns the Webpack configuration

  • .toString()

    Returns the Webpack configuration as a string.

• .getState()

  Returns the normalized configuration (prior to reducing).

  • .toString()

    Returns a string of the normalized configuraiton.
