Adeunis codecs

TypeScript project for JavaScript/Node.js library of Adeunis codecs.

This document explains how to modify, compile and package the library. For beginners, developments can be done directly on generated JavaScript files (no compilation).


A Node.js + npm environment is required to start developments:

  • Node.js 14.x, JavaScript runtime
  • npm, package manager for JavaScript (shipped with Node.js)

A knowledge of TypeScript language is also recommended.

Getting started

Go to project folder and install dependencies:

npm install

Please note that :

  • RTU firmware version has no impact on the codec type to select
  • Bundles use the same type than the standard product

Source code generation

To get version from package.json, do global npm run build

Quick demo (HTML pages)

Basic demo pages are available in generic\src\demo\ directory

You can also visit the demonstration web page

adeunis codecs in NPM repository

NPM package is available here : https://www.npmjs.com/package/@adeunis/codecs

Example to use it:

  • Create an empty directory npm_demo and go into it

  • Initialize npm project : npm init (accept all default choices)

  • Install adeunis codecs : npm i @adeunis/codecs

  • Install additional package if necessary : npm i @types/node

  • Create a file named demo.ts :

const codec = require('@adeunis/codecs');

// All product types are defined in DecoderProducts enum (src/shared/product.enum.ts)
const productType = 'analog';
const payloadValue = '42500110000002100000';
let payloadResult;

console.log(`Decoding ${productType} frame => ${payloadValue}`);

const decoder = new codec.Decoder();

// Configure the decoder for the appropriate device 

// Decode the given payload
let parserResult = decoder.decode(payloadValue);

// Incompatible frame and product
if (parserResult.error) {
    payloadResult = 'decoding issue';
} else {
    // Display result
    payloadResult = JSON.stringify(parserResult, null, 2);

  • Compile .ts file : tsc demo.ts
  • Execute demo : node demo.js
