This is a Node JS module to read music files from iRealPro.
The output is a JS object similar to the one shown below. Repeated measures, endings, segnos and codas are all expanded and written out serially in one array.

}Install the module with npm install ireal-reader. To save to your projects package.json, use npm install ireal-reader --save.
Then, in your project, read in the HTML or ireal://... url output from iRealPro.
The example below shows how to read the music from an HTML file using plain JavaScript:
const fs = require('fs');
const iRealReader = require('ireal-reader');
fs.readFile("ireal-output-file.html", "utf8", function(err, data) {
if (err) throw err;
const playlist = iRealReader(data);
}The example below shows how to read the music from an HTML file using TypeScript.
First, in your project, npm install ireal-reader-1.3.0.tgz --save. Also, for example, if you are using Angular2, you
might need a irealreader.d.ts file containing the text declare module 'ireal-reader'; in your app folder.
Then, load this library in your TypeScript class like so:
import * as iRealReader from 'ireal-reader';
Then, call it:
const iRealHtml: string = '<HTML ...';
const iRealJson = iRealReader(iRealHtml);
Feel free to fork or submit pull requests. Run tests with npm test
To develop and use the project locally, use npm pack. This will create a .tgz file that can be used locally by other modules. In your other project do npm install path/to/ireal-reader-xxx.tgz
