Deploy Node.js projects to AWS Lambda and API Gateway easily

Hello,

I have a web-api project with a few endpoint, and would like to include a new lambda which should be trigger via an event scheduler. Can I add a new js file in the project and set a claudia add-scheduled-event or it should be a new project separated from the web-api?

I tried to find an example of this in the git repo but didn't find any.

@lstone Can you share how you did it?

I have successfully run the hello world micro instance tutorial but don't see it populate on my aws account when I look in the browser. Am I missing something?

Is there no more active development on Claudia? Running into some problems cause I want to utilize the max memory limits as well as setting up an endpoint as HTTP_PROXY (would love suggestions on if I can achieve the latter through Claudia; my initial research shows that it hardcodes AWS_PROXY making this not possible without forking or updating).

I am having troubles throwing errors with different status codes on Claudia. I know with Express JS it would look something like res.status(400).send(), but with claudia its just a return so I'm not sure how to tackle it

Hello,

I am trying to update my lambda function with following command

claudia update --region us-west-2 --version qa2a --set-env env=qa2 --memory 4096 --timeout 30

But I get the following error

the memory value provided must be less than or equal to 3008

But the lambda function can have memory 10240

Any suggestions would be appreciated

Thank you!

I keep getting that error when I try to do claudia create, any ideas why?

I tried changing the node versions, but no luck.

When constructing an AWS Lambda function with Claudia, the docs say to do exports.handler = function (event, context) { and then to reference the payload parameters sent to the function using event.parameterName but when I do that and print the parameters to the console, they all say "undefined." Anyone know why?

I'm pretty sure I have used it before like that. I am wondering if there's been changes since the docs were written...maybe event.somenewsubproperty.parameterName or something?

Ah, nevermind, already figured it out. Alamofire changed a bit and I wasn't passing the parameters.

I'm trying to use Claudia.js for Lambda@Edge, but my Lambdas end up being wayyy to large. I tried downloading the Lambda package from AWS, and I see claudia inside my node_modules. I've confirmed that in my package.json, Claudia is a devDependency not a dependency. I'm probably doing something stupid

Hello,
I wanted to explore callbackWaitsForEmptyEventLoop parameter so I have created a lambda with the below code

var ApiBuilder = require('claudia-api-builder'),
    api = new ApiBuilder();

module.exports = api;

api.any('/test', function (request) {
    request.lambdaContext.callbackWaitsForEmptyEventLoop = true;

    var prefix = request.proxyRequest.queryStringParameters.id;
    console.log('hello: ' + prefix);
    setTimeout(function () {
        console.log('after timeout: ' + prefix);
    }, 5000);

    return new ApiBuilder.ApiResponse('OK ' + prefix, {'X-Version': '202', 'Content-Type': 'text/plain'}, 200);

});

The strange thing is I don't see the 'after timeout' message.

even on other requests

when I tried with callbackWaitsForEmptyEventLoop=false,

var ApiBuilder = require('claudia-api-builder'),
    api = new ApiBuilder();

module.exports = api;

api.any('/test', function (request) {
    request.lambdaContext.callbackWaitsForEmptyEventLoop = false;

    var prefix = request.proxyRequest.queryStringParameters.id;
    console.log('hello: ' + prefix);
    setTimeout(function () {
        console.log('after timeout: ' + prefix);
    }, 5000);

    return new ApiBuilder.ApiResponse('OK ' + prefix, {'X-Version': '202', 'Content-Type': 'text/plain'}, 200);

});

I got 'after timeout' but only when I sent two request (19 sec between each)

When I sent a third request (12 minutes later) the 'after timeout' message didn't appear

@ziedmahdi

@harblaith7 the easiest way is to use ApiResponse
return new ApiBuilder.ApiResponse('Request received', {'Content-Type': 'text/plain'}, 200);

Does anyone have working examples of accepting a multipart/form-data POST request containing binary content such as a png/jpeg? Specifically I'm trying to pass along a form value as well as a image file via a Postman post to an claudia api endpoint but I'm not seeing anything to indicate it's being attached to the request object. I'm using claudia-api-builder not the express wrapper.

I was able to get it working on lambda with busboy. For anyone who comes across this, I was never able to get it working locally via the claudia-local-api package, it appears multi-part forms are not supported with that currently
