This document will help the developer ( or third-party vendors ) to set up and use Discussion-middleware.

Background:

This discussions-middleware works like an API proxy. All the discussions-forum related APIs will go via this proxy.

Git Repository:

https://github.com/Sunbird-Ed/discussions-middleware

Prerequisite:

Local nodebb should be installed ( or for a particular environment )
Note: Refer to this link for easy installation: https://docs.nodebb.org/installing/os/
all the necessary plugins to be installed and activated for the nodebb to access certain APIs,

Steps to set up DMW locally :

Step-1 : Git clone:

> git clone git@github.com:Sunbird-Ed/discussions-middleware.git
> nvm use 12 (min node version 12)
> cd discussion-middleware
> yarn

Step-2: Add the following configuration in environmentVariablesHelper.js

'use strict'
const env = process.env
const __envIn = 'dev';

let localEnv = {
    NODEBB_SERVICE_URL: 'http://localhost:4567',
    Authorization:  <master token>,
    nodebb_api_slug: env.nodebb_api_slug || '/api'
}

module.exports = localEnv;

Replace the ‘<mater token>’ with your local NodeBB master token.

Q1. How to generate/get master token?
Ans. Local NodeBB should be running fine. Install the Write-API NodeBB plugin.
After successfull installation, generate the master token by refering below link.
