JavaScript Utilities

A library of constants and functions that should work in any

• typescript
• ecmascript
• javascript

The intention is that the library should not depend upon any node-module that doesn't work in at least these environments:

• Enonic XP serverside code
• Modern browser
• Newest LTS version of Node

It should work in at least these frameworks:

• React

Examples

DSL

import {storage} from '@enonic/js-utils';

const and = storage.query.dsl.and;
const bool = storage.query.dsl.bool;
const fulltext = storage.query.dsl.fulltext;
const ngram = storage.query.dsl.ngram;
const stemmed = storage.query.dsl.stemmed;

const fields = 'url^1.2,title^1.1,text';
const searchString = 'fun video';
const operator = 'OR';
const query = bool(and(
	fulltext(fields, searchString, operator),
	stemmed(fields, searchString, operator, 'no', 0.9),
	stemmed(fields, searchString, operator, 'en', 0.8),
	ngram(fields, searchString, operator, 0.7)
));
console.debug(JSON.stringify(query, null, 4));
