✨ Generate N'Zod contracts and DTOs from Prisma Schema ✨

Template Features

• 🚀 Blazingly fast and easy installation
• 💡 CI workflows configured for changelogs and release/prerelease cycles
• 🧱 Perfect and easy-to-support tooling setup without any conflicts with CI environment
• 📚 Well-documented conventions for project maintaining (commits, pull-requests, branches)

Before you start

The README on main branch may contain some unreleased changes.

Go to release/latest branch to see the actual README for the latest version from NPM.

Installation

yarn add @nzod/prisma

npm install @nzod/prisma

Usage

generator nzod {
  provider = "nzod-prisma"
  output   = "../src/generated/nzod"
}

What will be generated?

For each model:

• {ModelName}Schema

  Exact prisma -> nzod mapping.

• {ModelName}InputSchema

  The same as the regular schema, but nullable fields are optional.

• {ModelName}RelatedSchema

  If the model has relations, the related schema will be generated.
  It contains all fields from the regular schema plus relations.

• {ModelName}RelatedInputSchema

  If the model has relations, the related schema will be generated.
  It contains all fields from the input schema plus relations (optional when nullable).

• {ModelName}Dto (when generateDto is set to true)

  The DTO constructor for the regular schema.

• {ModelName}InputDto (when generateDto is set to true)

  The DTO constructor for the regular schema.

Creating DTOs

Install N'Zod DTO library:

yarn add @nzod/dto

npm install @nzod/dto

Set generateDto to true:

generator nzod {
  provider    = "nzod-prisma"
  output      = "../src/generated/nzod"
  generateDto = true
}

Using decimal.js for Decimal fields

Install decimal.js:

yarn add decimal.js

npm install decimal.js

Set useDecimalJs to true:

generator nzod {
  provider     = "nzod-prisma"
  output       = "../src/generated/nzod"
  useDecimalJs = true
}

Maintenance

The dev branch is main - any developer changes is merged in there.

Also, there is a release/latest branch. It always contains the actual source code for release published with latest tag.

All changes is made using Pull Requests - push is forbidden. PR can be merged only after successfull test-and-build workflow checks.

When PR is merged, release-drafter workflow creates/updates a draft release. The changelog is built from the merged branch scope (feat, fix, etc) and PR title. When release is ready - we publish the draft.

Then, the release workflow handles everything:

• It runs tests, builds a package, and publishes it
• It synchronizes released tag with release/latest branch

Regular flow

1. Create feature branch
2. Make changes in your feature branch and commit
3. Create a Pull Request from your feature branch to main
   The PR is needed to test the code before pushing to release branch
4. If your PR contains breaking changes, don't forget to put a BREAKING CHANGES label
5. Merge the PR in main
6. All done! Now you have a drafted release - just publish it when ready

Prerelease flow

1. Assume your prerelease tag is beta
2. Create release/beta branch
3. Create feature branch
4. Make changes in your feature branch and commit
5. Create a Pull Request from your feature branch to release/beta
   The PR is needed to test the code before pushing to release branch
6. Create Github release with tag like v1.0.0-beta, pointing to release/beta branch
   For next beta versions use semver build syntax: v1.0.0-beta+1
7. After that, the release workflow will publish your package with the beta tag
8. When the beta version is ready to become latest - create a Pull Request from release/beta to main branch
9. Continue from the Regular flow's #5 step

Conventions

Feature branches:

• Should start with feat/, fix/, docs/, refactor/, and etc., depending on the changes you want to propose (see pr-labeler.yml for a full list of scopes)

Commits:

• Should follow the Conventional Commits specification
• You can find supported types and scopes into .cz-config.js

Pull requests:

• Should have human-readable name, for example: "Add a TODO list feature"
• Should describe changes
• Should have correct labels (handled by PR Labeler in most cases)
