Express Env Middleware

This middleware helps you set environment variables for your running server via a HTTP post request.

Installation

npm install --save express-envset

    const express = require('express');
    const app = express();
    const envMiddleware = require('express-envset');
    const ENV_AUTHKEY = "XEF729_dfj@#raf";
    app.use(envMiddleware(process.env.ENV_AUTHKEY || ENV_AUTHKEY))

Testing

To test the module, run npm test on the command line of the project folder

Usage

    const express = require('express');
    const app = express();
    const envMiddleware = require('express-envset');
    const ENV_AUTHKEY = "XEF729_dfj@#raf";
    app.use(envMiddleware(process.env.ENV_AUTHKEY || ENV_AUTHKEY))

The environment variable middleware can also take an object as the only argument for its setup. The object has the following fields

• authKey (required): string representing the authentication string to prevent unauthorized access to the endpoint
• url (optional): the endpoint you want to use when updating environment variables via HTTP. It defaults to /envset

Update an environment variable

In other to update an environment variable via HTTP, use the following steps:

• Set the env_authkey request header
• The request method should be POST
• The request body should be JSON and should contain an env field that has values of the object type e.g:

    const requestBody = {
        "env":{
            "STRIPE_KEY": "str_ATfld37adfjlj"
        }
    }

The fully formed HTTP post request is

    curl -X POST --header "env_authkey: 123" -d '{"env":{"key1":"value1", "key2":"value2"}}' "http://www.myexpressapp.com/env/setup"
