Esbuild does not build on file change

[Edweis]

Describe the bug Running sls offline with a serverless.yml containing

custom:
  plugins:
    - serverless-esbuild
    - serverless-offline
  #esbuild: no extra esbuild setting

functions:
  testFn:
    handler: src/endpoints/index.handler
    events:
      - http:
          method: GET
          path: /hello

When editing the file src/endpoints/index.ts, calling the endpoint is using the version of the code when the first compilation started.

To Reproduce Steps to reproduce the behavior. If you have an example repository that would be even better:

1. Create a new project with the configuration above
2. in src/endpoints/index.ts, insert

   export const handler = async () => ({
   statusCode: 200,
   body: 'batman',
   });

3. run serverless offline
4. curl http://localhost:3000/dev/hello returns batman
5. change src/endpoints/index.ts, to

   export const handler = async () => ({
   statusCode: 200,
   body: 'robin',
   });

6. curl http://localhost:3000/dev/hello returns batman, expected robin

Versions (please complete the following information):

• OS: MacOs
• Serverless Framework Version: 3.24.1
• Plugin Version: 0.15.13

Had the same issue after serverless-offline upgrade, try adding reloadHandler: true to serverless-offline configuration.

Fixed it for me.

Thank you, it doesn’t work for me. I’ll check with serverless-offline

I am having the same issue, reloadHandler doesn't work for me either.

we just solved this, make sure you don't have any rules that would exclude everything in your pacakge option like this:

package:
  individually: true
  patterns:
    - '!**'
    - 'src/assets/*/**'

it was importing the ** pattern into our exclude
