Package Exports
- efrt
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (efrt) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
npm i efrt
efrt is a prefix/suffix trie optimised for compression of english words.
it is based on mckoss/lookups by Mike Koss and bits.js by Steve Hanov
- squeeze a list of words into a very compact form
- reduce filesize/bandwidth a bunch
- ensure unpacking overhead is negligible
- word-lookups are critical-path
By doing the fancy stuff ahead-of-time, efrt lets you ship much bigger word-lists to the client-side, without much hassle.
var efrt = require('efrt')
var words = [
'coolage',
'cool',
'cool cat',
'cool.com',
'coolamungo'
];
//pack these words as tightly as possible
var compressed = efrt.pack(words);
//cool0;! cat,.com,a0;ge,mungo
//create a lookup-trie
var trie = efrt.unpack(compressed);
//hit it!
console.log(trie.has('cool'));//true
console.log(trie.has('miles davis'));//falseDemo!
the words you input should be pretty normalized. Spaces and unicode are good, but numbers, case-sensitivity, and some punctuation are not (yet) supported.

var trie=unpack(compressedStuff);
trie.has('miles davis');
