Node.js
Install with npm package manager:
npm install kuromojiLoad this library as follows:
var kuromoji = require("kuromoji");You can prepare tokenizer like this:
kuromoji.builder({ dicPath: "path/to/dictionary/dir/" }).build(function (err, tokenizer) {
// tokenizer is ready
var path = tokenizer.tokenize("すもももももももものうち");
console.log(path);
});Browser
You only need the build/kuromoji.js and dict/*.dat.gz files
Install with Bower package manager:
bower install kuromojiOr you can use the kuromoji.js file and dictionary files from the GitHub repository.
