Linux Server Setup & MERN App Deployment

These are the steps to setup an Ubuntu server from scratch and deploy a MERN app with the PM2 process manager and Nginx. We are using Linode, but you could just as well use a different cloud provider or your own machine or VM.

The Arduino webserver library from the ESP8266 is very simple and you can get to its limits pretty fast!

So that beeing said I first want to recommend you this library: ESPAsyncWebServer.
It's a very good alternative with a lot of features and it's easy to use.

However I wanna show you an easy way to hack around the standard webserver library for projects which can't make use of the ESPAsyncWebserver library.

So what we want to do is making the ESP8266 serve files via its webserver that are bigger than the RAM size we have left.
A picture for example. You don't want to hold that in the RAM, it's limited and way to valuable to be used for this.

Simple automated deployment using git hooks

Here are the simple steps needed to push your local git repository directly to a remote (e.g. prod) server over ssh. This is based on Digital Ocean's Tutorial.

Overview

You are developing in a working-directory on your local machine, let's say on the master branch. Usually people push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use GitHub's webhooks to send a POST request to a webserver to take appropriate actions such as cloning/checking out a branch on the remote (prod) server.
