Moving from Gulp to webpack

I've been avoiding learning Webpack for a while now as I never thought I needed to learn another build tool, Gulp does everything I'd ever need from a build tool now or in the future. However, ever since we've moved from AngularJS to Angular (or Angular 2+) as well as introducing standards such as; TypeScript instead of Javascript and a Jasmine/Karma combo for UI testing, but also Webpack as an initial build tool. I've avoided it for long enough and now, in September 2017, I thought it's time to finally move on from my old friend Gulp.

Good Old Gulpfile

If you've never heard of Gulp before, this isn't the post to learn, there are plenty of good tutorials out there a Google search away. Then again, you don't really need to know Gulp to understand what's going on so feel free to continue reading nevertheless.

This is a simple way of importing MySQL database in Docker.

1. In you Dockerfile you must have a shared folder. Shared folder is a directory in your host machine that is mounted to Docker instance.

2. Put the exported sql file in the shared folder.

3. Login to your Docker instance via docker exec -it DOCKER_CONTAINER_ID bin/bash.

4. Login to MySQL via mysql -u USERNAME -p.

I don't like IDEs. I want to code in my editor and use the command line for everything else. I like the flow better and it feels faster to me.

I also like to have one command to do several things I want to do.

I don't want to open Xcode to create an archive, then open the archive window, then upload the archive to iTunes. It's slow and breaks my flow.

Also, in react native, it's trivial to build Android releases on the command line. I want to create and upload both iOS and android from the command line.

So after hours of searching the internet I found a flow I like for creating and uploading archives for iOS all from the command line
