Adding mock data to Supamode

How to add mock data to Supamode for development purposes

Seeding the data is optional, but it can help you get started with some demo data.

The repository comes with a predefined schema (based off of Makerkit's schema) and a seed file that you can use to populate your database with mock data.

The seed file uses Snaplet to generate realistic mock data based on the schema. This allows you to have a more realistic development environment.

Creating a Seed File

pnpm --filter app run supabase:seed:gen

This command creates a seed file at apps/app/supabase/seeds/03-demo-seed. sql.

Modifying the Seed File

The default seed file is the below:

import { copycat } from '@snaplet/copycat';
import { createSeedClient } from '@snaplet/seed';
(async () => {
  const seed = await createSeedClient({
    dryRun: true,
  });
  const { users } = await seed.users((x) =>
    x(10, (user) => {
      return {
        id: copycat.uuid(user.seed),
        email: copycat.email(user.seed),
        password: `testingpassword`,
        confirmation_token: copycat.uuid(user.seed),
        recovery_token: copycat.uuid(user.seed),
        email_change_token_new: copycat.email(user.seed),
      };
    }),
  );
  for (const user of users) {
    await seed.public_accounts(
      (x) =>
        x(1, (account) => {
          return {
            is_personal_account: false,
            name: copycat.fullName(account.seed),
            picture_url: null,
            notifications: (x) =>
              x({ min: 4, max: 20 }, (notification) => ({
                link: '',
                title: copycat.sentence(notification.seed),
                body: copycat.paragraph(notification.seed),
              })),
            subscriptions: (x) =>
              x(1, () => ({
                billing_provider: 'stripe',
                subscription_items: () => x(1),
              })),
            invitations: (x) =>
              x(3, (invitation) => ({
                email: copycat.email(invitation.seed),
                role: 'member',
                status: 'pending',
              })),
          };
        }),
      {
        connect: {
          users,
        },
      },
    );
    await seed.blog_posts(
      (x) =>
        x({ min: 4, max: 20 }, (blogPost) => ({
          title: copycat.sentence(blogPost.seed),
          tags: [copycat.word(blogPost.seed), copycat.word(blogPost.seed)],
          content: [
            copycat.paragraph(blogPost.seed),
            copycat.paragraph(blogPost.seed * 2),
            copycat.paragraph(blogPost.seed * 3),
            copycat.paragraph(blogPost.seed * 4),
          ].join('\n\n'),
          blog_post_comments: (x) =>
            x({ min: 0, max: 50 }, (comment) => ({
              content: copycat.paragraph(comment.seed),
              author_email: copycat.email(comment.seed),
            })),
        })),
      {
        connect: {
          users,
        },
      },
    );
  }
  process.exit(0);
})();
