docs: prisma generate post install

[schalkneethling]

The docs at https://github.com/prisma/docs/blob/main/content/100-getting-started/02-setup-prisma/100-start-from-scratch/120-mongodb/200-install-prisma-client.mdx states that prisma generate is automatically run after running npm install @primsa/client.

I ran the npm command using both Node v16.x and v18.x and with neither was prisma generate automatically run afterward. I do have a schema file at prisma/schema.prisma.

Just found this on a different page: https://www.prisma.io/docs/concepts/components/prisma-client/working-with-prismaclient/generating-prisma-client#the-prismaclient-npm-package:

This command also runs the prisma generate command, which generates the Prisma Client into the node_modules/.prisma/client directory.

I checked and node_modules/.prisma/client does indeed exist. Again though, running the install command only shows the following output:

❯ npm i @prisma/client

Apologies for all the comments 😄, I keep finding other pieces and putting it all together.

What I did in the end is install prisma using:

❯ npm i --save-dev prisma

added 2 packages, and audited 62 packages in 12s

7 packages are looking for funding
  run `npm fund` for details

found 0 vulnerabilities

I added the following to scripts in package.json:

"prisma:generate": "prisma generate",

Running the script target now gave me this output:

❯ npm run prisma:generate

> artic-sidekick-api@0.0.1 prisma:generate
> prisma generate

Environment variables loaded from .env
Prisma schema loaded from prisma/schema.prisma

✔ Generated Prisma Client (4.0.0 | library) to ./node_modules/@prisma/client in 54ms
You can now start using Prisma Client in your code. Reference: https://pris.ly/d/client

import { PrismaClient } from '@prisma/client'
const prisma = new PrismaClient()

npm does not output postinstall script's output any more since a few versions.
If you start with an empty project (but a schema.prisma file) and then isntall prisma and @prisma/client you should have a generated Client in node_modules/.prisma/client which indicates that prisma generate was indeed run under the hood.

Thank you for the reply, I got everything working. It might be useful to update the docs to reflect this change. Happy to do it if you agree.

I am not sure what there is to update, but of course a PR would make that clear - so go ahead and link to it here.

TODO

• Clarify postinstall step is run and shouldn't expect any output because it generation happens silently
