Client-side Search component


About

This uses Lunr.js to perform a client-side search of a site's content.

Usage

This approach is recommended only for sites with a limited number of pages (around 500 or fewer), otherwise the client side search index can become many megabytes in size.

If your site is in a subdirectory or has other requirements, you specify any required prefix to your search URL with data-vf-search-client-side-destination-prefix="https://myprefix".

$3

This is an early alpha. More customisation options need to be added, such as:

- passing search parameters (boost score) to the JS
- customising the output format
- NJK template has hardcoded paths for vf-core

$3

This consumes a .js file with a searchIndex object of pages, a la:

``json
let searchIndex = {
"pages": [
{"id":"0", "title": "Page title", "text": "Body text of page goes here", "tags": "", "url": "/index.html"},
...
]
};
`

To make this index, you can utilise the ability of vf-extension to generate a search index.

1. Making an index

To generate that JS file, if you're using a vf-eleventy based site, you may also want to make use of the vf-extensions's gulp-build-search-index.js:

> require('./node_modules/\@visual-framework/vf-extensions/utils/gulp-build-search-index.js')(gulp, path, buildDestionation);

2. Dependencies

If you use that JS you'll also need some npm dependencies:

yarn add strip-js striptags node-html-parser

3. Tell gulp to make the index

And you should build that search index after updating your html pages, a la:

`
// build search index after search page is compiled
gulp.watch(['./build/search/index.html'], gulp.parallel('vf-build-search-index'));

// And for your build task
gulp.task('build', gulp.series(
...
'eleventy:build',
'vf-build-search-index',
...
));

// And for your dev task
gulp.task('dev', gulp.series(
...
'eleventy:build',
'vf-build-search-index',
...
));
`

$3

- You can pass a query to the search page with ?search_query=myQuery
- The search will live update as the user enters text
- You can enable autofocus on the search element, but should only do so if most users intend to search on the page

Install

This repository is distributed with npm. After installing npm, you can install vf-search-client-side with this command.

`
$ yarn add --dev @visual-framework/vf-search-client-side
`

$3

The style files included are written in Sass. If you're using a VF-core project, you can import it like this:

`
@import "@visual-framework/vf-search-client-side/index.scss";
`

Make sure you import Sass requirements along with the modules. You can use a project boilerplate or the vf-sass-starter`
