Redwood's HTTP server for serverless Functions
The dev server looks for "lambda functions" in ./api/src/functions.
Each lambda function is mapped to a URI based on their filename, as
an example: ./api/src/functions/graphql.js would be accessible
at http://localhost:8911/graphql.
The ./api directory is watched for modifications, when they are
detected the modules are reimported.
A lambda function must export a handler. You can execute the
supplied callback function to return a response:
export const handler = (event, context, callback) => {
return callback(null, { status: 200, body: 'Hello, world' })
}Request Handlers
At the moment we emulate AWS Lambda functions, but there are other serverless providers that have different request/ response signatures that we would like to support as a deploy target.
We think we have two approaches for making that possible:
- Converge on the AWS Lambda Functions format and convert "other" providers signatures at build time.
- Provide a way to emulate other function providers in the Redwood Function Server (Which is why this folder exists.)
We have not made a decision on which approach is better.
