The TRIE data structure and search algorithm, on top of leveldb.
npm install level-trieThe TRIE data structure and search
algorithm, on top of leveldb.
Store some words in a trie, then query them:
``js
var level = require('level');
var Trie = require('level-trie');
var db = level(__dirname + '/db');
var trie = new Trie(db);
trie.add('bar');
trie.add('baz');
trie.add('foo');
trie.createSearchStream('fabulous')
.on('data', console.log);
// => foo
// => bar
// => baz
`
Create a new Trie that stores its data in db.
If you don't want to use a whole database for the trie, pass in a
database's section using
level-sublevel.
Add string to the trie. This causes a batch operation with as many puts asstring
characters in + 1.
Remove string from the trie.
Create a readable Stream that emits all the strings stored in the trie,stream#end
ordered by size of the common prefix. Abort reading with or uselimit
the option.
Possible options are:
* limit: Emit max. x entries.follow
* : Keep the stream open and emit new data that comes in. When used inlimit
conjunction with the last emitted historical entry will define the
border of what a new entry that's emitted needs to fit in, e.g. it mustn't be
further away from the search string.
With npm do:
`bash``
$ npm install level-trie
