v0.10.0 - The one with seed.ts

[justinvdm]

We recently added a new feature to our snaplet cli: snaplet seed - a way to populate an empty database with generated data.

In this release, you're now able to configure how this seed data looks - in much the same way as how you might've configured how snaplet transforms your production data before.

When you run snaplet config setup, or snaplet config generate -t seed, we'll now generate an example .snaplet/seed.ts config file in your project dir. It'll look something like this:

// This is an example config generated by snaplet.
// It shows how you can override the default data generated by `snaplet seed`.
// Add more columns, tables, or schemas to override this default data.
import { copycat, faker } from "@snaplet/copycat";
import type { Transform } from "./structure";

export const config: Transform = () => ({
  public: {
    User({ row }) {
      return {
        name: copycat.fullName(row.name),
      };
    },
  },
}); 

The file shows an example of how you can configure seed. In this case, row.name represents the value snaplet has generated for the name column in the User table for a particular row.

Lets say your name column was actually representing first names rather than full names. You could change it to something like this:

export const config: Transform = () => ({
  public: {
    User({ row }) {
      return {
        name: copycat.firstName(row.name)
      };
    },
  },
});
