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

Ross Coundon

@rcoundon

You can’t continue Lambda execution after returning a result to the API Gateway, that’s not Claudia API Builder limitation, it’s the AWS feature. However, you can send a background message using the SNS notification (or SQS, EventBridge, etc.) and continue running in the background.
If you are generating the file, it would be similar to the following:

HTTP request sends the SNS message, and then returns a presigned URL

Frontend pings that S3 URL each second to see if it’s ready

The SNS message triggers another Lambda function that does the logic in the background and saves the result to the S3 file.

Thanks @stojanovic - that's almost exactly the pattern I went with, except using SQS instead of SNS

The endpoint creates the S3 file and returns a presigned URL, and writes a msg (basically the original request + filename) to an SQS queue
A separate lambda has the SQS queue as a trigger and processes the data, and replaces the S3 file (using same key)
The frontend polls for a file using the presigned URL with content

Hi guys

I made some modifications in my code

but when I updload the code to AWS

using Claudia

the process is not including those changes

do you know if Claudia have a command to clean cache or something like that

Hello guys, when run:
claudia update --use-local-dependencies
Happens:
npm ERR! code EEXIST npm ERR! path /private/var/folders/gp/tksqwx0x3w96hnd2p_zczk480000gp/T/tKqD1w/quryappgwaws-1.0.0-HAkaXS/package/node_modules/claudia/node_modules/aws-sdk/node_modules/.bin/uuid

I am following this guide:
Building a Serverless Application in AWS using React and Claudiajs

Hey everyone

I'm trying to come up with a solution to get multiple params

I found that aws promotes the usage of multiValueQueryStringParameters in here https://aws.amazon.com/es/blogs/compute/support-for-multi-value-parameters-in-amazon-api-gateway/

Is there anyway to do this using the same handler locally?

hi ...newbie...here can i integrate claudia with MS Teams?

Slobodan Stojanović

@stojanovic

You can use the Claudia API Builder to build your own integration, but you can’t do it using the Claudia Bot Builder.

Loredo Sola

@loredo_sola_twitter

Does Claudia deploy to HTTP API? Does Claudia integrate with firebase auth/JWT?

Slobodan Stojanović

@stojanovic

I want to write a blog post about serverless MS Teams bot using SAM (we use it for https://vacationtracker.io) but I don’t have time to do that right now, it’ll probably be ready in a few weeks

@loredo_sola_twitter no HTTP API integration at the moment. But if you want to add it feel free to send a PR, I can probably help with that.

Just discovered Claudia and have begun reading the documentation. Can Claudia Bot Builder be used to create bots using either Amazon Lex or Google Dialogflow? In other words, is a bot built with Claudia portable between the two bot engines?

Hi, I get "BadRequestException: Endpoint Configuration type EDGE is not supported in this region: cn-northwest-1" while creating Lambda function. How can I avoid this?

Hi, I want to use nodegit in my lambda function, this requires access to the local file system. Does lambda even has a "local file system" or if it doesn't and I need to attach some other AWS resource (s3?) to mimic the fs, can claudia help with that?

Hi, I'm using claudia pack with an npm package that is a workspace (npm 7). It looks like dependent workspaces do not get installed... is this a bug? Or maybe a future enhancement? Thanks.

You can access the /tmp folder but you can't rely on anything you write there being available on other runs. There's now EFS support in lambda too but I'm not familiar with it yet.

Hi everyone, so I'm facing some problems with claudia bot builder, Does any one know how to fix, what I'm doing wrong ?

'OAuth "Facebook Platform" "invalid_request" "(#100) The parameter subscribed_fields is required.-

Here is my configuration

`
"scripts": {
"create": "claudia create --api-module bot --region eu-west-1 --configure-fb-bot",
"configure-fb": "claudia update --configure-fb-bot",
"deploy": "claudia update"
},
"dependencies": {
"claudia": "^5.12.0",
"claudia-bot-builder": "^4.5.0"
}

@honkskillet

Does claudia support Node v14?

Reik Schatz

@reik-wargaming

@honkskillet AWS Lambda does not directly support Node14.x as runtime yet. AWS will probably add that soon.

Hi, when using the add-scheduled-event, I want to be able to run it to change an existing schedule.

Currently if I run add-scheduled-event twice with two different --cron defintions, it creates two identical targets in the EventBridge, under one rule...

Am I doing something wrong?

So, does anyone have recommendations for doc generation with Claudia?

I'm actually getting this exact same problem! I could use some help, if anyone has any ideas.

Hi! I want to propose a very slight change to claudia. I need to deploy a lambda with the new max memory that is 10240, but we need to change that in src/utils/limits.json.

Victor Wiebe

@victorwiebe

Hello there, I am experiencing CORS issues.

Environment is claudiajs deploying to lambda

I can test properly from Postman

CORS issues on Website itself when testing on localhost:3000

Please advise

Victor Wiebe

@victorwiebe

So Basically, on the website doesnt work, on Postman works perfectly

Sethupathy

@Sethupa14919203_twitter

Map your api gateway url to DNS, will sort out the CORS issue

Hello, I'm using Claudia.js and Claudia-api-builder to deploy a Lambda function (works great). Currently this function has API Gateway as an event source. I'd like this same Lambda function to be able to alsp listen to SNS events Additionally, I'd like a specific function inside the Lambda codebase to be invoked upon receiving an SNS event. Is there a way to do this w/ Claudia.js in conjunction w/ the api builder?

lstone

Follow up - I've sorted this out ^

Hi all,

I'm trying to run the Hello World AWS Lambda Function following the steps in the tutorial.

I ran

claudia create --profile claudia --region us-east-1 --handler lambda.handler

but the output I got is this error

validating package      npm dedupe -q --no-package-lock
npm dedupe -q --no-package-lock failed.

and the file claudia.json is not created.

I'm using claudia 5.13.0, Node.js 14.16.0, npm 7.5.6 on Ubuntu 18.04.5 LTS .

Any suggestion?
Thank you

Bruno M.

@brunosmm

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.

Bruno M.

@brunosmm

@lstone Can you share how you did it?

AlfredMadere

@AlfredMadere

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?

Sam Baek

@sambaek-rapidai

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).
