gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

ffmpeg
- macOS: brew install ffmpeg
- Ubuntu/Debian: apt install ffmpeg

This tutorial uses the "Sample hapi.js REST API" project.

	* Using Operator Mono in Atom
	*
	* 1. Open up Atom Preferences.
	* 2. Click the “Open Config Folder” button.
	* 3. In the new window’s tree view on the left you should see a file called “styles.less”. Open that up.
	* 4. Copy and paste the CSS below into that file. As long as you have Operator Mono SSm installed you should be golden!
	* 5. Tweak away.

	Disclaimer: The instructions are the collective efforts from a few places online.
	Nothing here is my original. But I want to put them together in one place to save people from spending the same time as I did.

	First off, bundle.
	==================

	1. cd to the project directory
	2. Start the react-native packager if not started
	3. Download the bundle to the asset folder:
	curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"
