ENOENT: no such file or directory, lstat '/Users/home/roam/backend/.build/.serverless'

[kvarela]

First off, thanks for continuing this project. I'm having a really hard time figuring out how to get my serverless typescript function small enough to upload to Lambda, and I really hope this works.

I'm getting the error:
ENOENT: no such file or directory, lstat '/Users/home/roam/backend/.build/.serverless'

I don't know why it's looking in /.build/.serverless. My .serverless dir is at the same level as ./build. Is there a config option I need to set to make this work?

Here's my stacktrace:

Hi @kvarela !

Are you sure this issue is related to this plugin? Surveying the stack trace you provided, I couldn't find any entries related to serverless-plugin-browserifier.

You can see plugin and PluginManager_ everywhere because that's the way serverless works behind the scenes: everything is a plugin, including its internal functionalities, like deploy`, which seems to be the one blowing up, given the lines below:

Error: ENOENT: no such file or directory, lstat '/Users/home/roam/backend/.build/.serverless'
    at PluginManager.invoke (/Users/home/.config/yarn/global/node_modules/serverless/lib/classes/PluginManager.js:390:22)
    at PluginManager.spawn (/Users/home/.config/yarn/global/node_modules/serverless/lib/classes/PluginManager.js:408:17)
    at Deploy.BbPromise.bind.then.then (/Users/home/.config/yarn/global/node_modules/serverless/lib/plugins/deploy/deploy.js:123:50)

Anyway, a few ways to find that out:

• use sls package, which avoids deployment, but builds the packages
• remove the plugin from your serverless.yml, and verify whether the deployments happens without issues

Hi @nolde, thanks for your response. I am sure this plugin is causing the issue. I can successfully deploy and run without the plugin. I get the same error when I run sls package

Could you tell me which version of the plugin you are using and, if equal or above v2, could you tell me the version of browserify being used?

Also, I can see that you are using serverless-plugin-typescript. Those two plugins might conflict with each other, as both are trying to modify the input data.

If you want to use browserify, I recommend transpiling to typescript through it, using a plugin like tsify. Add it to your project, and configure serverless-plugin-browserifier to use it like this:

custom:
  browserify:
    transform:
      - - tsify
        - noImplicitAny: true

More info:

• tsify
• Integrating with build tools: browserify

[kvarela]

Hi @nolde, sorry for the delay. I'm suing serverless-plugin-browserifier v2.0.0 and browserify v16.2.2.

Using the tsify plugin allows me to package and upload to Lambda, but when I try to run, I get:

Handler 'handler' missing on module 'src/handlers/graphql'

This is all that I see uploaded to Lambda so it appears all my code and dependencies did not get included.

Here's what my serverless.yml looks like now:

package:
    individually: true
    excludeDevDependencies: true
    include:
        - src/**/*.js

functions:
    graphql:
        handler: src/handlers/graphql.handler
        memorySize: 512 # optional, in MB, default is 1024
        timeout: 30 # optional, in seconds, default is 6, API Gateway timeout is 30s
        events:
            - http:
                  path: graphql
                  method: post
                  cors: true

    ean-update:
        handler: src/handlers/ean-update.handler
        timeout: 300
        events:
            - schedule(1 day)

plugins:
    - serverless-plugin-browserifier
    - serverless-offline

custom:
    browserify:
        debug: true
        transform:
            - tsify
            - noImplicitAny: true

Any ideas?

[nolde]

Hi @kvarela !

As a quick answer, your transform is wrong. This may or may not be the reason for your issue.

If you want to use tsify options, such as noImplicitAny, you format should be as follows (pay attention to the equivalent JSON version added):

WITH tsify options

# yml
custom:
  browserify:
    transform:
      - - tsify                             # array of array, two dashes!
        - noImplicitAny: true

// json
{
  "custom": {
    "browserify": {
      "transform": [
        ["tsify", { "noImplicitAny": true }] // array of array!
      ]
    }
  }
}

If you don't need any options, you can simplify it to the config below:

WITHOUT tsify options

# yml
custom:
  browserify:
    transform:
      - tsify           # single dash, simple array

// json
{
  "custom": {
    "browserify": {
      "transform": ["tsify"]  // simple array
    }
  }
}

You also probably want to remove package.include and package.excludeDevDependencies, as package construction is handled by browserify.

I will take another look by the end of the week!

Thanks @nolde, was able to get it working.

[nolde]

Sweet!

I'm glad to find out it works fine with TypeScript as well!
