A simple parser for advanced search query syntax.
It parses a string like this:
from:hi@retrace.io,foo@gmail.com to:me subject:vacations date:1/10/2013-15/04/2014 photos
And turns it into an object like this:
{
from: ['hi@retrace.io', 'foo@gmail.com'],
to: 'me',
subject: 'vacations',
date: {
from: '1/10/2013',
to: '15/04/2014'
},
text: 'photos'
}$ npm install search-query-parservar searchQuery = require('search-query-parser');
var query = 'from:hi@retrace.io,foo@gmail.com to:me subject:vacations date:1/10/2013-15/04/2014 photos';
var options = {keywords: ['from', 'to', 'subject'], ranges: ['date']}
var searchQueryObj = searchQuery.parse(query, options);
// searchQueryObj.from is now ['hi@retrace.io', 'foo@gmail.com']
// searchQueryObj.to is now 'me'
// searchQueryObj.date is now {from: '1/10/2013', to: '15/04/2014'}
// searchQueryObj.text is now 'photos'You can configure what keywords and ranges the parser should accept with the options argument. It accepts 2 values:
keywords, that can be separated by commas (,)ranges, that can be separated by a hyphen (-) Both values take an array of strings, as in the example just above.
The 15 tests are written using the BDD testing framework should.js, and run with mocha.
Run npm install should and npm install -g mocha to install them both.
Run tests with mocha -R spec.
