elm serverless

Deploy an elm HTTP API to AWS Lambda using serverless. Define your API in elm and then use the npm package to bridge the interface between the AWS Lambda handler and your elm program.

Documentation

• ./demo - Best place to start learning about the framework. Contains several small programs each demonstrating a separate feature. Each demo is supported by an end-to-end suite of tests.
• elm-serverless-demo - Demo programs that work with the latest release.
• API Docs - Hosted on elm-lang packages, detailed per module and function documentation. Examples are doc-tested.

Middleware

• ktonon/elm-serverless-cors - Add CORS to your response headers.
• ktonon/elm-serverless-auth-jwt - Authorization using JSON Web Tokens (JWT)

elm-serverless's Issues

JavaScript interop

Currently its possible to extend the framework easily to support calling out to javascript through a port, but getting the port to send back a message to elm is trickier. There needs to be a way of encoding the plug id.

Elm 0.19 and future plans?

Hi @ktonon , I missed this project on Elm 0.19 as I was using it with 0.18 and finding it to be a great way of writing lambda functions for AWS.

I have created a PR that upgrades to 0.19, completing the work started by ream88.

I don't know if you want to go on with this project and maintaining it under 0.19 or not? Just considering my options on how best to get my upgrade published, as I could always just fork it. Not sure yet if I will just continue to use it as is, or if I would like to make some more substantial changes and take it in a new direction, so thought it best to get your thoughts first.

Update dependencies

The build specific modules can be upgraded to their recent versions:

serverless-webpack: 5.1.5
webpack: 4.6.x

However, this requires some changes in the serverless.yml and more important, the webpack.config.js files. For a sample webpack configuration with Webpack 4.x see the babel-webpack-4 folder in the serverless-webpack examples.
Also, the babel-loader has to be updated to at least 7.1.3 for webpack 4.

Elm 0.19

Hi,
I'm really keen to try to use your package. However, I couldn't install it with elm 0.19. Is it depending on some features which have been removed from 0.19 or can I help with the upgrade?

demo doesn't work out of the box

...unless you have serverless installed globally and aliased to sls. A couple other missing dependencies for the demo.

I'll have a fix incoming.
