sveltekit-adapter-html-like
Warning
SvelteKit is still under heavy development and introduces breaking changes every now and then. If this adapter doesn't work in your setup, make sure to use
@svelte/[email protected].
Adapter for SvelteKit apps that prerenders your site as static files for template engines such as PHP, Blade, Embedded Ruby (ERB), Handlebars, EJS etc.
This package is a fork of @sveltejs/adapter-static that adds a couple of extra features:
- tag injection
- string replacement
- minify/prettify output
- custom file extensions
Usage
Install with npm i -D sveltekit-adapter-html-like, then add the adapter to your svelte.config.js:
// svelte.config.js
import adapter from 'sveltekit-adapter-html-like';
export default {
kit: {
adapter: adapter()
}
};Unless you're in SPA mode, the adapter will attempt to prerender every page of your app, regardless of whether the prerender option is set.
Options
pages
Type: string
Default: build
The directory to write prerendered pages to. It defaults to build.
assets
Type: string
Default: build
The directory to write static assets (the contents of static, plus client-side JS and CSS generated by SvelteKit) to. Ordinarily this should be the same as pages, and it will default to whatever the value of pages is, but in rare circumstances you might need to output pages and assets to separate locations.
fallback
Type: string
Default: null
Specify a fallback page for SPA mode, e.g. index.html or 200.html or 404.html.
precompress
Type: boolean
Default: false
If true, precompresses files with brotli and gzip. This will generate .br and .gz files.
injectTo
Type: object
Default: {}
Allows the injection of markup, valid HTML or otherwise, into the <head> or <body>. You can use the same positions as insertAdjacentHTML:
beforebeginafterbeginbeforeendafterend
Example
Let's inject some WordPress tags into the page
adapter({
injectTo: {
head: {
beforeend: ['<?php wp_head(); ?>']
},
body: {
beforeend: ['<?php wp_footer(); ?>']
}
},
targetExtension: '.php'
});replace
Type: array
Default: []
String replacements run on every page
Example
Once again, a WordPress example
adapter({
replace: [
{
from: '<html lang="en">',
to: '<html <?php language_attributes(); ?>>'
// many: true (optional)
}
],
targetExtension: '.php'
});minify
Type: boolean
Default: false
Enable minification of output files
targetExtension
Type: string
Default: .html
Modifies the extension of the target file, e.g. .php or .hbs
SPA mode
You can use sveltekit-adapter-html-like to create a single-page app or SPA by specifying a fallback page.
In most situations this is not recommended: it harms SEO, tends to slow down perceived performance, and makes your app inaccessible to users if JavaScript fails or is disabled (which happens more often than you probably think).
The fallback page is a blank HTML page that loads your SvelteKit app and navigates to the correct route. For example Surge, a static web host, lets you add a 200.html file that will handle any requests that don't otherwise match. We can create that file like so:
// svelte.config.js
import adapter from 'sveltekit-adapter-html-like';
export default {
kit: {
adapter: adapter({
fallback: '200.html'
})
}
};When operating in SPA mode, only pages that have the prerender option set will be prerendered.
