Build Profiler




Getting Started

To begin, you'll need to install `webpackbar`:

Using npm:

```bash
npm install webpackbar -D
```

Using yarn:

```bash
yarn add webpackbar -D
```

Then add the reporter as a plugin to your webpack config.

**webpack.config.js**

```js
const webpack = require("webpack");
const WebpackBar = require("webpackbar");

module.exports = {
context: path.resolve(__dirname),
devtool: "source-map",
entry: "./entry.js",
output: {
filename: "./output.js",
path: path.resolve(__dirname),
},
plugins: [new WebpackBar()],
};
```

Options

### `name`

- Default: `webpack`

Name.

### `color`

- Default: `green`

Primary color (can be HEX like `#xxyyzz` or a web color like `green`).

### `profile`

- Default: `false`

Enable profiler.

### `fancy`

- Default: `true` when not in CI or testing mode.

Enable bars reporter.

### `basic`

- Default: `true` when running in minimal environments.

Enable a simple log reporter (only start and end).

### `reporter`

Register a custom reporter.

### `reporters`

- Default: `[]`

Register an Array of your custom reporters. (Same as `reporter` but array)

Custom Reporters

Webpackbar comes with a fancy progress-bar out of the box.
But you may want to show progress somewhere else or provide your own.

For this purpose, you can provide one or more extra reporters using `reporter` and `reporters` options.

**NOTE:** If you plan to provide your own reporter, don't forget to setting `fancy` and `basic` options to false to prevent conflicts.

A reporter should be instance of a class or plain object and functions for special hooks. It is not necessary to implement all functions, webpackbar only calls those that exists.

**Simple logger:**

```js
{
start(context) {
// Called when (re)compile is started
},
change(context) {
// Called when a file changed on watch mode
},
update(context) {
// Called after each progress update
},
done(context) {
// Called when compile finished
},
progress(context) {
// Called when build progress updated
},
allDone(context) {
// Called when _all_ compiles finished
},
beforeAllDone(context) {
},
afterAllDone(context) {
},
}
```

`context` is the reference to the plugin. You can use `context.state` to access status.

**Schema of `context.state`:**

```js
{
start, progress, message, details, request, hasErrors;
}
```
