kandi X-RAY | aws-serverless-express Summary

aws-serverless-express is a JavaScript library typically used in Manufacturing, Utilities, Machinery, Process, Serverless, Nodejs, Express.js applications. aws-serverless-express has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can install using 'npm i @techfirst/aws-serverless-express' or download it from GitHub, npm.

On 11/30, the AWS Serverless Express library is moving to Vendia and will be rebranded to serverless-express. Similarly, the aws-serverless-express NPM package will be deprecated in favor of a new serverless-express package. Brett, the original creator of the Serverless Express library, will continue maintaining the repository and give it the attention and care it deserves. At the same time, we will be looking for additional contributors to participate in the development and stewardship of the Serverless Express library. AWS and the SAM team will remain involved in an administrative role alongside Vendia, Brett, and the new maintainers that will join the project. We believe this is the best course of action to ensure that customers using this library get the best possible support in the future. To learn more about this move or become a maintainer of the new Serverless Express library, reach out to us through a GitHub issue on this repository. Best, The AWS Serverless team, Brett & the Vendia team.

In AWS Lambda using Node, can't get Express to work with aws-serverless-express

Asked 2022-Mar-15 at 18:33

Below is my sample code that is not working. No matter what I set up, I can't get Express to render my ejs page.

Note: I have an API Gateway in front of the Lambda. That will only let in the traffic I want. Everything that hits my Lambda should have the express page rendered. While not in the code I am showing below, once working, I will do some validation and lookups before using express to show the page.

Umzug Migration UP with Aws Lambda function not working

I have built a test app using nestjs + Sequelize ORM + docker database (as of now local). As per documentation, I am using umzug library and AWS Lambda SAM template and triggering lambda handler. Below is the code for it. Connection Pooling is implemented to reuse existing sequelize connection. Below is the lambdaEntry.ts file where I trigger umzug.up() function. It is triggering but not migrating files.

When done from command prompt node migrate up it works correctly. I am testing using sam invoke command to test it.

TL;DR prefer the SDK's async-await patterns.

Here is an example of consecutive async-await calls using the AWS SDK for JavaScript v3.^*. Note the async keyword in the function signature and the await keyword before the promise-returning method calls. The docs have the complete client initialization code.

ANSWER

Answered 2022-Jan-28 at 10:12

Your have a problem with your preflight request. A preflight request ist only sent by browsers and not by tools like Postman, so that is why the Postman request is still working.

The preflight request is an OPTIONS request, so please check that you have an OPTIONS method in API Gateway for the path your are requesting, and check its configuration and that you for example aren't sending or expecting credentials with the OPTIONS request. Including credentials in a preflight request ist not allowed according to the Mozilla CORS Documentation.

A reason why the request stops working after adding another path might be that you have made manual changes (perhaps regarding Authentication or CORS) to your API in the API Gateway Console. When you then push the same API with Amplify those changes are often overwitten. Please check that this isn't the case. And try to make all changes through the Amplify API (if you have created the API there) to avoid those problems.

This problem is caused by the archiverjs/node-archiver dependency used inside serverless when running on node version 15.6.0 or higher currently.

As many proposed here downgrading the node version to the current LTS version v14.15.4 or v15.5.1 should work just fine as MX D mentioned in his comment.

Many people are experiencing this issue when building their bundles inside a CI/CD Pipeline, because they are using a node docker image. For example in GitLab like:

AWS Lambda + Angular web app throwing "Error: Cannot find module '@vendia/serverless-express'"

Asked 2020-Dec-25 at 15:24

I am trying to deploy angular web app on AWS serverless Lambda following the tutorial https://medium.com/better-programming/getting-started-with-serverless-angular-universal-on-aws-lambda-8754bcc4dc19

It was working fine till last week, but started to throw error "Error: Cannot find module '@vendia/serverless-express'" even though there is no mention of '@vendia/serverless-express' anywhere. The generated lambda.js uses'aws-serverless-express'.

Installed '@vendia/serverless-express' through npm, it got added to package.json. Deployed post that, still error is reported.

Steps to reproduce:

Ensure angular version is 7 or less as toolkit doesn't work with higher version
ng new project-name --style css --routing false
cd project-name
ng add @ng-toolkit/universal@7.1.2
npm run build:prod
npm run server
ng add @ng-toolkit/serverless@8.1.0
npm i serverless-api-compression
npm run build:serverless:deploy

Let me know in case of any further information required. Thanks in advance!

aws-serverless-express has rebranded to @vendia/serverless-express. The new path is not yet included in ng-toolkit's serverless-aws.yml file and that is what is causing the issue.

Adding the following in the serverless.yml excludes would solve the issue.
