edfjs

A lean javascript implementation of European Data Format.

Installation

Install with npm

To use the library for your website, you can install the npm package:

npm i edfjs

Use it in your javascripts, e.g., with:

const fs = require('fs');
const edfjs = require("edfjs");
const edf = new edfjs.EDF();
const fp = fs.readFileSync("./examples/sample.edf");
edf.read_buffer(fp.buffer);

Include module from CDN

The module can be used in your webpage by including the following link from jsdelivr CDN:

<script src="https://cdn.jsdelivr.net/npm/edfjs@latest/dist/edf.min.js"></script>

Build the module locally

Browserify and Minify is used to build the module as a standalone library so that you can import it into your own scripts. To build, git-clone yourself a local copy of master ``, cd edfjs, and build it with npm using `npm run build`:

git clone https://github.com/jusjusjus/edfjs.git
cd edfjs
npm install --only=dev
npm run build

A stand-alone version of the library, ./dist/edf.min.js, should appear. Before you need to install other dependencies.

Usage

In ./web, we give an example usage of edfjs directly included in an html document. Build the minified module using npm run build, start serving ./web/index.html and load an edf file for demo.

Tests

To test run:

npm run test

Jest

If you encounter trouble testing your code that uses edfjs (By default "node_modules" folder is ignored by transformers), please add a "jest.config.js" to your project with the following content:

const esModules = ['edfjs'].join('|');
module.exports = {
  transformIgnorePatterns: [`/node_modules/(?!${esModules})`]
}
