django-ts 0.1.0

Generate TypeScript constants and enums from Django model

django-ts

Generate TypeScript constants and enums from Django models. No more copy-pasting values between backend and frontend.

Why?

You've got Django models with constants:

class Order(models.Model):
    STATUS_PENDING = "pending"
    STATUS_CONFIRMED = "confirmed"
    STATUS_SHIPPED = "shipped"

    STATUS_CHOICES = [
        (STATUS_PENDING, "Pending"),
        (STATUS_CONFIRMED, "Confirmed"),
        (STATUS_SHIPPED, "Shipped"),
    ]

    status = models.CharField(max_length=20, choices=STATUS_CHOICES)

And you need the same values in TypeScript. You could copy them manually, forget to update one side, ship a bug, debug for an hour, then remember why you hate manual syncing.

Or just run:

python manage.py synctypes

What you get

constants.ts

export const Order = {
  STATUS_CONFIRMED: "confirmed",
  STATUS_PENDING: "pending",
  STATUS_SHIPPED: "shipped",
} as const

enums.ts

export enum OrderStatusEnum {
  STATUS_PENDING = "pending", // Pending
  STATUS_CONFIRMED = "confirmed", // Confirmed
  STATUS_SHIPPED = "shipped", // Shipped
}

index.ts

export * from "./constants";
export * from "./enums";

Requirements

• Python 3.10+
• Django 4.0+

Installation

pip install django-ts-constants

Add to INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    "django_ts_constants",
]

Usage

# Generate to ./frontend/constants (default)
python manage.py synctypes

# Custom output directory
python manage.py synctypes --output ./frontend/src/generated

# Check mode - exits 1 if files are outdated (for CI)
python manage.py synctypes --check

# Dry run - see what would change without writing
python manage.py synctypes --dry-run

What gets exported

The command scans your project's Django apps and extracts:

• Uppercase constants with underscores (STATUS_PENDING = "pending")
  • Strings, integers, floats
• Choice tuples (STATUS_CHOICES = [(value, label), ...])
  • Become TypeScript enums with labels as comments

Third-party packages are ignored. Only your project's apps are scanned.

CI integration

# GitHub Actions
- name: Check TypeScript constants are in sync
  run: python manage.py synctypes --check

If someone updates a Django constant but forgets to regenerate the TypeScript files, CI fails. No more "works on my machine" surprises.
