$ npm install flow-parser
This package contains the Flow parser in its compiled-to-JavaScript form.
See flow.org. The code for the Flow parser lives on GitHub.
The Flow Parser is a JavaScript parser written in OCaml. It produces an AST that conforms to the ESTree spec and that mostly matches what esprima produces. The Flow Parser can be compiled to native code or can be compiled to JavaScript using js_of_ocaml. This npm package contains the Flow parser compiled to JavaScript.
You can use the Flow parser in your browser or in node. To use in node you can just do
require('flow-parser').parse('1+1', {});
To use in the browser, you can add
<script src="flow_parser.js"></script>
which will make the flow
object available to use like so:
flow.parse('1+1', {});
