Advanced tools
serverless-lambda-router is a router framework to be used within a single lambda function supporting an API Gateway stage. Note that this library requires a lambda runtime of 6.10
.
serverless-lambda-router operates around promises, so use of async / await with babel is encouraged. To deliver a response, resolve the handler with the payload. To deliver an error, throw the Boom error.
Originally developed for use with the serverless framework.
npm install --save serverless-lambda-router
const Boom = require('boom');
const LambdaRouter = require('serverless-lambda-router');
// Create a router instance
const router = new LambdaRouter({
// Headers to be attached to response payload
headers: {
'Cache-Control': 'max-age=0, private, no-cache, no-store'
},
// Function to be notified before route invoke
onInvoke: event => {},
// Function to be notified when route throws
onError: (err, event) => {}
});
// Register handlers
router.get('/foo', async (event, context) => {
// To deliver a response, return a Promise and resolve with your
// intended payload. If using async / wait, you can simply return the payload.
return {
foo: 'bar'
};
});
router.get('/bar', async (event, context) => {
// To deliver a response, return a Promise and throw an error.
// If using async / wait, you can simply throw the error.
throw Boom.notFound('Resource not found');
});
// Multiple handlers can be registered for a given route.
// Handlers may communicate via `context.state`, and the result of the final
// handler determines the response.
router.get('/baz', async (event, context) => {
context.state.name = 'John Smith';
}, async (event, context) => {
return {
name: context.state.name
};
});
// Export the handler
exports.handler = router.handler();
