@scloud/lambda-api v0.2.3
Lambda API Gateway Proxy handler
A Lambda handler that routes API Gateway Proxy messages and returns an API Gateway Proxy Response.
This is a piece of useful boilerplate to handle the mechanics of routing, headers and cookies, catching any errors and handling 400, 405 and 500 errors (you can optionally handle 404 and 500 with your own handler functions).
Releae notes
0.2.1
: Request headers are now made available in lowecase as well as their original case. The response body can now bestring
as well asobject
.0.2.2
: AddContent-Type: text/plain
for string responses if not already set.
Usage
Create your routes:
import { types } from '@scloud/lambda-api';
const routes: types.Routes = {
'/ping': { GET: async (request: types.Request) => ({ statusCode: 200, body: {message: 'ok'} }) },
}
Use @scloud/lambda-api
in your Lambda handler:
import { APIGatewayProxyEvent, APIGatewayProxyResult, Context } from 'aws-lambda';
import { apiHandler, helpers } from '@scloud/lambda-api';
export async function handler(event: APIGatewayProxyEvent, context: Context): Promise<APIGatewayProxyResult> {
const result = await apiHandler(event, context, routes);
return result;
}
The apiHandler
function will call your route functions according to the method and path of the request, catching any errors and returning 404/405 if a path/method isn't defined, or 500 if an error is thrown.
