RiTa for JavaScript
RiTa is implemented in JavaScript and Java, with a common API for both, and is free/libre/open-source.
Note: version 3.0 contains breaking changes -- please check the release notes
import { RiTa } from "https://esm.sh/rita";
$ npm install rita
let { RiTa } = require('rita');
<script src="https://unpkg.com/rita"></script>
<script src="https://unpkg.com/rita"></script>
import { RiTa } from "https://esm.sh/rita";
// to analyze a sentence
let data = RiTa.analyze("The elephant took a bite!");
console.log(data);
// to load a grammar
let grammar = RiTa.grammar(rulesObjectOrJSON);
console.log(grammar.expand());
RiScript (the minor language that powers RiTa) was designed specifically for writers working with code. RiScript primitives (choices, symbols, gates, transforms, etc) can be used as part of any RiTa grammar or executed directly using RiTa.evaluate. For more info, see this interactive notebook on observable.
To install/build the library and run tests (with npm/mocha and node v14.x):
$ git clone https://github.com/dhowe/ritajs.git
$ cd ritajs
$ npm install
$ npm run build
$ npm test
If all goes well, you should see a list of successful tests and find the library built in 'dist'
Please make contributions via fork-and-pull - thanks!
Once you have things running with npm/mocha/tsup, you might also try VSCode.
Some of the following extensions may also be useful:
Here you can see the tests in the VSCode Testing view
Create a new file on your desktop called 'test.html' with the following lines, save and drag it into a browser:
<html>
<script src="https://unpkg.com/rita"></script>
<script>
window.onload = function() {
let words = RiTa.tokenize("The elephant took a bite!");
document.getElementById("content").innerHTML = words;
};
</script>
<div id="content" width=200 height=200></div>
<html>
Create a new file on your desktop called 'test.html' with the following lines, save and drag it into a browser:

Create a new file on your desktop called 'test.html' with the following lines, save and drag it into a browser:
<html>
<script src="https://unpkg.com/p5"></script>
<script src="https://unpkg.com/rita"></script>
<script>
function setup() {
createCanvas(200,200);
background(245);
textAlign(CENTER);
textSize(20);
let words = RiTa.tokenize("The elephant took a bite!")
for (let i=0; i < words.length; i++) {
text(words[i], 100, 50 + i*20);
}
}
</script>
</html>
If you already have a sketch, simply add <script src="https://unpkg.com/rita"></script>
to your index.html to include RiTa.
To install: $ npm install rita
let RiTa = require('rita');
let data = RiTa.analyze("The elephant took a bite!");
console.log(data);
