vite-plugin-twig
⚠️ Notice
This documentation refers to the version 2.x of the plugin. Take a look here for older releases or check out the migration guide.
Installation
npm i -D vite-plugin-twigUsage
/* vite.config.js */
import { defineConfig } from 'vite'
import twig from 'vite-plugin-twig'
export default defineConfig({
// ...
plugins: [
twig({ /* ...options */ })
]
})Options
The plugin can be configured both directly with the options parameter shown above or via the dedicated twig.config.(js|ts) file, like following:
/* twig.config.js */
import { defineConfig } from 'vite-plugin-twig'
export default defineConfig({
// ...
})ℹ️ defineConfig is a bypass function with type hints, which means you can also omit it if you don't need the autocompletion/typecheck.
Here below the list of the supported options.
cache
type: boolean
default: false
If true, it enables internal Twig's template caching.
extensions
type: { filters: TwigExtensions, functions: TwigExtensions }
default: undefined
A collection of custom filters and functions to extend Twig. Look at twig.js documentation to learn more.
fileFilter
type: (filename: string) => boolean
default: undefined
A custom filter to determine if the current transforming .html file should be processed/ignored or not (useful for improving compatibility with other plugins).
Example:
/* twig.config.js */
import { defineConfig } from 'vite-plugin-twig'
export default defineConfig({
// ...
fileFilter: filename => filename.endsWith('.twig.html')
})fragmentFilter
type: TwigFragmentFilter
default: undefined
A custom filter to determine if the current matched fragment should be processed/ignored or not (useful for improving compatibility with other plugins).
Example:
/* twig.config.js */
import { defineConfig } from 'vite-plugin-twig'
export default defineConfig({
// ...
fragmentFilter: (fragment, template, data) => {
return fragment.indexOf('data-engine="twig"') > -1
// or template.endsWith('.twig')
// or data.engine === 'twig'
}
})globals
type: { [key: string]: any }
default: undefined
The global variables to be injected in each template.
settings
type: { views: any, 'twig options': any }
default: undefined
The Twig settings. Please refer to twig.js documentation and types to learn more.
Templates
The .html files located by default in the Vite project root are not intented to be replaced directly by the .twig ones since the normal page files resolution/linking on the Vite's dev server is wanted to be preserved along with the build logic. However, those files are enabled to contain special script tags which will be treated as placeholders for contents you want to delegate to Twig.
More in details, a .html file could look like this:
<!-- index.html -->
<script type="application/json" data-template="path/to/template.twig">
{
"foo": "bar"
}
</script>where the data-template attribute defines the path (relative to the cwd) of the .twig file to be rendered in place of the script tag, whose content (optional) represents instead a JSON definition of the local context to be injected in the template (possibly merged with the globals provided via plugin options).
Take a look here for a clearer example.
ℹ️ The application/json type is not mandatory, but it is recommended for syntax highlighting and linting purposes.
The plugin also supports a promiscuous templates handling, allowing you:
- to have .html files with both standard and Twig based code
- to render (multiple) Twig fragments within a standard .html page
This could be useful, for instance, when you want to use Twig for new implementations without having to refactor an existing code base.
With that in mind, a .html file could look as follows:
<html>
<body>
<!-- existing contents -->
<script type="application/json" data-template="path/to/fragment-a.twig">
{
"foo": "bar"
}
</script>
<!-- existing contents -->
<script type="application/json" data-template="path/to/fragment-b.twig"></script>
<!-- existing contents -->
</body>
</html>Take a look here for a clearer example.
