Abstract
The ternwords JavaScript library parses the contents of a SITEWORDS file into memory for use with the rwt-search DOM component.

Motivation

Websites using the rwt-search DOM component need to access a ternary-trie of words and the documents where those words are found. This library is used to populate that ternary-trie with the contents of a file retrieved via an AJAX call.

Installation

The ternwords library may be installed directly from github or via NPM.

Node.js

To add the library to a node.js project, use this command:

[user@host]# npm install ternwords

Node.js project usage:

import FileInterface  from '/node_modules/ternwords/esm/file-interface.class.js';
import TernWords from '/node_modules/ternwords/esm/tern-words.class.js';

var fileInterface = new FileInterface();
var ternWords = new TernWords();
fileInterface.readSiteWords('sitewords-data', ternWords);

Browser

To add the library to a browser project, use this command:

[user@host]# git clone https://github.com/readwritetools/ternwords.git

Browser project usage:

import TextInterface  from '/ternwords/esm/text-interface.class.js';
import TernWords from '/ternwords/esm/tern-words.class.js';

var textInterface = new TextInterface();
var ternWords = new TernWords();
var textBlob = localStorage.getItem('sitewords-data');
var textInterface.readSiteWords(textBlob, this.ternWords);
