Usage with NestJS

[Will-Mann-16]

I'm trying to deploy a NestJS project to lambda, and I want to use this plugin to reduce the file sizes down so I can deploy without errors. At the moment I'm getting this error: `Error: Parsing file /Users/willmann/Documents/Programming/uni-haus/server/node_modules/fast-glob/out/readers/stream.js: Unexpected token (16:10) at Deps.parseDeps (/Users/willmann/Documents/Programming/uni-haus/server/node_modules/serverless-plugin-optimize/node_modules/module-deps/index.js:519:15) at getDeps (/Users/willmann/Documents/Programming/uni-haus/server/node_modules/serverless-plugin-optimize/node_modules/module-deps/index.js:447:44) at /Users/willmann/Documents/Programming/uni-haus/server/node_modules/serverless-plugin-optimize/node_modules/module-deps/index.js:430:38 at ConcatStream.

`

I have tried this with different approaches - building using nestjs then deploying, same error. I've also tried excluding the modules responsible, but that just results in a different error of 'fast-glob module not found' on lambda, and 'cannot find module xxx' offline (xxx being my custom ts file containing a class type). Does anyone have any ideas? All help is greatly appreciated. (This project does work with the regular NestJS start, and I was following this tutorial)

I'm experiencing the same issue.

@nestjs/graphql uses a dependency, globby. The dependency globby uses a dependency fast-glob fast-glob#3.x is compiled into es2017 which breaks the parsing of serverless-plugin-optimize. In a nutshell, the fast-glob package needs to be compiled to es5. I did a quick/hacky fix that works. When I have time, I will create a more elegant solution. In your nestjs package.json, add the following to your dev-dependencies:

• "fast-glob": "3.2.5",
• "serverless-plugin-fix-optimize-bug": "https://github.com/andrew-talentfish/serverless-plugin-fix-optimize-bug.git"

You saved my bacon, thanks!

@Will-Mann-16 For the later versions of nestjs/graphql, this fixes the fast-glob issue. However, there is another dependency, fsevents, where "optimize" tries to include a binary and fails. I think a better approach is to use external option as follows:

external: ['fsevents', 'fast-glob']

I was struggling getting this to work as other errors appeared. If this doesn't work for you, baseline your project using https://github.com/hardyscc/aws-nestjs-starter. It doesn't use the optimize plugin, but I'm able to get the app under 45MB with the latest and greatest libs including typeorm, graphql, etc... Deploys no problem to serverless.
