Gif Download Server

This is the server component that converts a gif to the binary 565 format that is best for the blocks.

Prerequisites

You'll need Node.js and Yarn installed to run this locally. On macOS this might be something like:

# Install Node Version Manager
brew install nvm


Don't forget to add the necessary things to your .zshrc/.bashrc for NVM that Homebrew tells you to!

Install Node

nvm install node

Install yarn

curl -o- -L https://yarnpkg.com/install.sh | bash


Running locally

To run this locally, you can run the following.

yarn
HTTP=1 yarn dev


Your server should now be availble at <![CDATA[]]>http://localhost:3000<![CDATA[]]>. Make sure to change the serverURL on the block (main.cpp:174) to point to your new server.

Deploying

Left for reference, though you probably don't want to do this unless youre @magus.

# deploy a staging instance
yarn deploy


deploy to production (https://blockswithscreens.now.sh)

yarn deploy:prod


Debugging
