export type ContentCallback = (fileName: string) => string | null | undefined

## Usage
In most cases, just use the `string` format as a plugin option.
### Basic usage
Add it to `vite.config.ts`
```ts
// vite.config.ts
import banner from 'vite-plugin-banner'
// Other dependencies...
export default defineConfig({
plugins: [banner('This is the banner content.')],
})
```
When you run `npm run build` on your project, In the `dist` folder(Or the [build.outDir](https://vitejs.dev/config/#build-outdir) in `vite.config.ts` you configured), Except for `vendor` files, all `js` and `css` files will add a banner to the top.
e.g. in `app.b3a7772e.js`:
```js
/* This is the banner content. */
var e=Object.assign;import{M as t,d as a,u as r,c......
```
### Advanced usage
Of course, the most ideal banner is related to your package information.
First, You need to update your `package.json` like this, For example, it contains such field content:
```json
{
"name": "chengpeiquan.com",
"version": "0.1.0",
"description": "My personal website, technology stack based on Vue.js 3.0, and Vite 2.0, use Server Side Generation.",
"author": "chengpeiquan",
"homepage": "https://chengpeiquan.com/"
}
```
Then, import the `package.json` into `vite.config.ts`, update the banner like this:
```ts
// vite.config.ts
import pkg from './package.json'
// Other dependencies...
export default defineConfig({
plugins: [
banner(
`/**\n * name: ${pkg.name}\n * version: v${pkg.version}\n * description: ${pkg.description}\n * author: ${pkg.author}\n * homepage: ${pkg.homepage}\n */`
),
],
})
```
Run `npm run build`, you can see the banner become more detailed.
e.g. in `app.6936be52.js`:
```js
/**
* name: chengpeiquan.com
* version: v0.1.0
* description: My personal website, technology stack based on Vue.js 3.0, and Vite 2.0, use Server Side Generation.
* author: chengpeiquan
* homepage: https://chengpeiquan.com/
*/
var e=Object.assign;import{M as t,d as a,u as r,c......
```
### Fun usage
If you want to make some banners that show your personality, you can make some interesting content from some online generators.
Such as:
- [http://www.network-science.de/ascii/](http://www.network-science.de/ascii/)
- [https://www.bootschool.net/ascii](https://www.bootschool.net/ascii)
```ts
// vite.config.ts
export default defineConfig({
plugins: [
banner(`
██ ██ ███████ ██ ██ ████████ ██ ██ ███████ ██ ██
░██ ░██ ██░░░░░██ ░██ ░██░██░░░░░ ░░██ ██ ██░░░░░██ ░██ ░██
░██ ░██ ██ ░░██░██ ░██░██ ░░████ ██ ░░██░██ ░██
░██ ░██ ░██ ░██░░██ ██ ░███████ ░░██ ░██ ░██░██ ░██
░██ ░██ ░██ ░██ ░░██ ██ ░██░░░░ ░██ ░██ ░██░██ ░██
░██ ░██ ░░██ ██ ░░████ ░██ ░██ ░░██ ██ ░██ ░██
░██ ░████████ ░░███████ ░░██ ░████████ ░██ ░░███████ ░░███████
░░ ░░░░░░░░ ░░░░░░░ ░░ ░░░░░░░░ ░░ ░░░░░░░ ░░░░░░░
`),
],
})
```
Run `npm run build`, e.g. in `app.d9a287b8.js`:
```js
/*
██ ██ ███████ ██ ██ ████████ ██ ██ ███████ ██ ██
░██ ░██ ██░░░░░██ ░██ ░██░██░░░░░ ░░██ ██ ██░░░░░██ ░██ ░██
░██ ░██ ██ ░░██░██ ░██░██ ░░████ ██ ░░██░██ ░██
░██ ░██ ░██ ░██░░██ ██ ░███████ ░░██ ░██ ░██░██ ░██
░██ ░██ ░██ ░██ ░░██ ██ ░██░░░░ ░██ ░██ ░██░██ ░██
░██ ░██ ░░██ ██ ░░████ ░██ ░██ ░░██ ██ ░██ ░██
░██ ░████████ ░░███████ ░░██ ░████████ ░██ ░░███████ ░░███████
░░ ░░░░░░░░ ░░░░░░░ ░░ ░░░░░░░░ ░░ ░░░░░░░ ░░░░░░░
*/
var e=Object.assign;import{M as t,d as a,u as r,c......
```
### Add different banners
Since `0.6.0`, it supports incoming function callback to set the content of Banner. When using `ContentCallback` type, this plugin will judge what content should be added according to the internal logic of the function.
1. When a valid string is returned, it will become the banner content
2. Returning a [Falsy](https://developer.mozilla.org/en-US/docs/Glossary/Falsy) value will skip processing(e.g. `''`, `null`, `undefined`)
e.g.
```ts
// vite.config.ts
import banner from 'vite-plugin-banner'
// Other dependencies...
export default defineConfig({
plugins: [
banner((fileName: string) => {
// Or use switch statement
return fileName.endsWith('.js')
? 'This message will inject into `js` files.'
: 'This message will inject into other files.'
}),
],
})
```
### Optional parameter format
Sometimes plugins can't get `outDir` successfully (for example, in VitePress, the plugin get through `viteConfig.build.outDir` is always a `.temp` temporary directory, not the final output directory), so you need to manually specify the output directory to inform the plugin.
Take VitePress as an example:
```ts
// docs/.vitepress/config.ts
import { defineConfig } from 'vitepress'
import banner from 'vite-plugin-banner'
import pkg from '../../package.json'
const outDir = '../dist'
export default defineConfig({
// Specify the output directory for packaging
outDir,
// Use Vite plugins
vite: {
plugins: [
// Please remember to use the options in Object format here
banner({
outDir,
content: `/**\n * name: ${pkg.name}\n * version: v${pkg.version}\n * description: ${pkg.description}\n * author: ${pkg.author}\n * homepage: ${pkg.homepage}\n */`,
}),
],
},
// ...
})
```
In addition to `outDir`, you can also use `debug`, `verify` and other options, see the above [Options](#options) description for details.
