2 |
3 | [](https://www.npmjs.com/package/gulp-svelte)
4 | [](https://travis-ci.com/shinnn/gulp-svelte)
5 | [](https://coveralls.io/github/shinnn/gulp-svelte?branch=master)
6 |
7 | A [gulp](https://github.com/gulpjs/gulp) plugin to compile [Svelte](https://svelte.technology/) templates to JavaScript
8 |
9 | ## Installation
10 |
11 | [Use](https://docs.npmjs.com/cli/install/) [npm](https://docs.npmjs.com/about-npm/).
12 |
13 | ```
14 | npm install --save-dev gulp-svelte
15 | ```
16 |
17 | ## API
18 |
19 | ```javascript
20 | const gulpSvelte = require('gulp-svelte');
21 | ```
22 |
23 | ### gulpSvelte([*options*])
24 |
25 | *options*: `Object` ([options for Svelte compiler API](https://github.com/sveltejs/svelte#compiler-options) and [`preprocess` option](#optionspreprocess))
26 | Return: [`stream.Transform`](https://nodejs.org/api/stream.html#stream_class_stream_transform)
27 |
28 | ```javascript
29 | const {dest, src, task} = require('gulp');
30 | const gulpSvelte = require('gulp-svelte');
31 |
32 | task('default', () => {
33 | return src('index.html') // index.html: 'Hi {{author}}.
'
34 | .pipe(gulpSvelte())
35 | .pipe(dest('dest')); // dest/index.js: 'function create_main_fragment ( state, component ) { ...'
36 | });
37 | ```
38 |
39 | Note:
40 |
41 | * `format` option doesn't support legacy JavaScript formats `amd`, `iife` and `umd`.
42 | * `onerror` option is not supported.
43 | * If `css` option receives `false`, it also emits an extracted CSS as a separate [`Vinyl`](https://github.com/gulpjs/vinyl) object with a `.css` file extension.
44 |
45 | ```javascript
46 | const {dest, src, task} = require('gulp');
47 | const gulpSvelte = require('gulp-svelte');
48 |
49 | task('default', () => {
50 | return src('source.html') // source.html: 'Hello
'
51 | .pipe(gulpSvelte({css: false}))
52 | .pipe(dest('dest'));
53 | // dest/source.js: '... p = createElement("p"); p.className = "svelte-16e8uch"; ...'
54 | // dest/source.css: 'p.svelte-16e8uch{color:red}'
55 | });
56 | ```
57 |
58 | #### options.preprocess
59 |
60 | Type: `Object`
61 |
62 | Modify contents with [`svelte.preprocess()`](https://github.com/sveltejs/svelte#preprocessor-options) passing this option to it before compiling the template.
63 |
64 | ```javascript
65 | const {dest, src, task} = require('gulp');
66 | const gulpSvelte = require('gulp-svelte');
67 |
68 | task('default', () => {
69 | return src('index.html') // index.html: 'original'
70 | .pipe(gulpSvelte({
71 | preprocess: {
72 | markup({content}) {
73 | return {code: content.replace('original', 'modified')}
74 | }
75 | }
76 | }))
77 | .pipe(dest('dest')); // dest/index.js: '... b = createElement("b");\n\t\t\tb.textContent = "modified"; ...'
78 | });
79 | ```
