Let's say you have a Bash shell script, and you need to run a series of operations on another system (such as via ssh). There are a couple of ways to do this.

First, you can stage a child script on the remote system, then call it, passing along appropriate parameters. The problem with this is you will need to manually keep the remote script updated whenever you change it -- could be a bit of a challenge when you have something to execute on a number of remote servers (i.e., you have a backup script running on a central host, and it needs to put remote databases in hot backup mode before backing them up).

Another option is to embed the commands you want to run remotely within the ssh command line. But then you run into issues with escaping special characters, quoting, etc. This is ok if you only have a couple commands to run, but if it is a complex piece of Bash code, it can get a bit unwieldy.

So, to solve this, you can use a technique called rpcsh -- rpc in shell script, as follows:

Configuring Emacs for react, es6, and flow

For a while, JSX and new es6 syntax had flaky support in emacs, but there's been huge work on a lot of packages. Using emacs for JavaScript with React, ES6, and Flow (or Typescript, etc) is really easy and powerful in Emacs these days.

This is how you can work on modern web development projects with full support for tooling like JSX, Flow types, live eslint errors, automatic prettier.js formatting, and more.

Set up web-mode

web-mode provides most of the underlying functionality, so a huge shout-out to the maintainer(s) there.
