A small uploader application I wrote as a demonstration for a blog post based on

• React (w/ TypeScript)
• Relay (modern) w/ react-relay-network-modern
• Elixir/Phoenix w/ Absinthe & Absinthe.Relay

This is mostly to demonstrate how one can facilitate single file uploads with Absinthe and Relay modern.

The more interesting parts are:

• The multipart middleware for react-relay-network-modern
• The resolver taking in the file and handling it to the Context

If you want to execute this project, you can use docker-compose to run it:

$ docker-compose pull

and a

$ docker-compose up -d

should do it.

I've included a relay compiler compatible image, so you can run everything inside the docker container:

# to generate graphql types via relay
$ docker-compose exec app yarn relay --watch

# for a production build
$ docker-compose exec app yarn deploy

Please note that you do not have to run yarn for development, as the Application will keep a watcher up.

Send me an email or open an issue, both is fine. I am always interested in feedback.

• relay environment docs
• The uploader discussion on complying with the suggestion for the multipart request spec, which absinthe does not support (as of yet)
• The Apollo upload client which supports the spec
• The most excellent @ScripterSugar providing the middleware for the nodejs based reference middleware
