Lunr Search Index

About

Small module to generate a lunr index with result store.

Can e.g. be used to generate a search index for a static website, generated with hugo, jekyll, gatsby or manually.

Usage

First you have to install this package, then create the index that you use on e.g. a search page. Find samples for everything in the following chapters.

Installation

Use npm install --save-dev mvw-search-index to add the dependency to your package.json.

Index creation

There are multiple possibilities to generate the script. Some are demonstrated in the following sub chapters:

• From CLI
• From TypeScript
• From nodejs

From CLI

mvw-search-index <glob> <destination> [css-selector]

For example:

mvw-search-index ./build/**/*.html ./build/index.json

Or from an npm script e.g. for a hugo page (has to be executed after page creation, obviously):

{
  "scripts": {
    "index": "mvw-search-index './public/**/*.html' './static/suche/index.json' 'main'"
  }
}

From TypeScript

import { SearchIndex } from "mvw-search-index";

let index = SearchIndex.createFromHtml(files, bodySelector);
// or: let index = SearchIndex.createFromInfo(info);
// or: let index = SearchIndex.createFromGlob(glob, bodySelector, cb);

fs.writeFileSync("index.json", JSON.stringify(index));

From node.js

"use strict";

const index = require("mvw-search-index");
const fs = require("fs")

index.SearchIndex.createFromGlob("./build/**/*.html",
                                 "main",
                                 (index) => fs.writeFileSync("./static/suche/index.json",
                                                             JSON.stringify(index)));

Sample usage of the created index

You can run npm run serve from this repository to run the sample site contained in ./demo.

This contains a very basic static website with a search form on the landing page index.html.
