If you have a cool idea, feature or bug you want to add then fork, clone and create a pull request.

Philosophy

Pragmatic: Discuss this solution on GitHub so that we can get a clear objective of what you are trying to achieve.
Simplistic: Take the simplest approach to meet your objective. Stay functional and extract complicated logic into simple functions.
Easy: Make it easy read (for humans and machines) and make it easy to modify and extend.
Consistent: Stick to existing conventions prominently visible in the file you are working on. (ie. no semi colons)
Confidence: Test where you can.

Testing locally

From source

Copy the entire project into the project plugins directory.

mkdir -p /path/to/project/plugins/gatsby-remark-interactive-gifs cp . /path/to/project/plugins/gatsby-remark-interactive-gifs

From build

yarn run build which will produce gatsby-node.js and index.js files.
Move the generated files to the project you wish to test in.

mkdir -p /path/to/project/plugins/gatsby-remark-interactive-gifs mv gatsby-node.js index.js /path/to/project/plugins/gatsby-remark-interactive-gifs cp package.json /path/to/project/plugins/gatsby-remark-interactive-gifs
Remove the package from the package.json.

Release

Steps to releasing a new package: (notes for future me)

npm run release to bump the version in package.json, create a release commit and tag it with that version number.
git push -u origin master --tags to push the latest changes with the newly created tag.
npm publish latest version of the package to the world.
