AWS Lambda + Angular web 应用抛出“错误：找不到模块‘@vendia/serverless-express’”

Question

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:

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

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

Answer 1

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.

- '!node_modules/@vendia/**'

End result would be something like

package:
  exclude:
   - src/**
   - node_modules/**
   - firebug-lite/**
   - e2e/**
   - coverage/**
   - '!node_modules/@vendia/**'
   - '!node_modules/aws-serverless-express/**'
   - '!node_modules/binary-case/**'
   - '!node_modules/type-is/**'
   - '!node_modules/media-typer/**'
   - '!node_modules/mime-types/**'
   - '!node_modules/mime-db/**'
