NestJs error compilation

[JCLMAQ]

1. Prisma2 version (prisma2 -v): preview021
2. Logs from Developer Tools Console, if any: I run prisma2 within a nestjs backend. When I start prisma2 studio with nestjs running, I get the following nestjs compliation error related to the auto created studio folder (within the prisma folder):

   
   > nest start --watch

11:55:38 - Starting compilation in watch mode...

6 export declare const brightBlue: chalk.Chalk;

Is there any way to avoid those errors ?

3. Does the issue persist even after updating to the latest `prisma2` alpha (`npm i -g prisma2@alpha`)?

4. Prisma2 schema (if relevant):

[JCLMAQ]

Error stay with preview022. Adding within package.json (devDependencies):

"@prisma/sdk": "^0.0.208",
    "@prisma/engine-core": "^2.0.110",
    "@prisma/generator-helper": "^0.0.40",
     "chalk": "^3.0.0",

avoid errors linked to @prisma unless the one related to "chalk".

Hey @JCLMAQ, thanks for reporting this! Do you have a simple repo where I can see this as well?

I haven't used NestJS before, but I think autogenerated files should be excluded from compilation. Either way, an example repo would help me dig deeper!

[JCLMAQ]

There is an invitation for the repo I use: https://github.com/JCLMAQ/nestjs-prisma2-jcm/invitations I still have the error for 'Chalk', but for now NestJS don't stop anymore...

Hey, I'm going to transfer this to the prisma2 repo, since this does not seem specific to Studio, but rather something with the prisma2 CLI's build. @pantharshit00 can then take a look. Could you share your repo with him as well? (Or perhaps make it public?) He also pointed me to a NestJS template a community member made that you might find useful to compare to: https://github.com/fivethree-team/nestjs-prisma-starter

Might I also suggest turning on esModuleInterop in your tsconfig as the error states and see if that helps?

[JCLMAQ]

Thanks for the reply. To start with prisma2 and Nestjs in fact I did use the NestJS template you point out . @pantharshit00 an invitation for the repo (still private for know) https://github.com/JCLMAQ/nestjs-prisma2-jcm/invitations

[JCLMAQ]

Adding "esModuleInterop = true" in nestjs config.ts solve the issue. Thanks. I should read error state more often ...

@JCLMAQ Sorry for the late reply here, but can this be closed now as this is resolved? Can you please confirm?

[JCLMAQ]

Yes. Thank you.
