Add or change a database table in a create-bun-api project (SQLite via bun:sqlite) using an append-only migration and a typed repository. Use when asked to add a model, table, column, index, or relation, or to persist new data.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Add or change a model
1. **Append a migration** to `src/db/migrations.ts` with the next id (`000N_<verb>_<table>`). Never edit,
reorder, or delete a migration that may already have run somewhere.
2. **SQL conventions:**
- Ids are `INTEGER PRIMARY KEY AUTOINCREMENT`. Columns are `snake_case`.
- Timestamps: `TEXT NOT NULL DEFAULT (strftime('%Y-%m-%dT%H:%M:%fZ', 'now'))`.
- Foreign keys are enforced. Write `REFERENCES users(id) ON DELETE CASCADE` and index every
foreign key column.
- Use `COLLATE NOCASE` for case-insensitive unique text such as emails.
- One migration may contain several statements.
```ts
{
id: "0002_create_notes",
sql: `
CREATE TABLE notes (
id INTEGER PRIMARY KEY AUTOINCREMENT,
user_id INTEGER NOT NULL REFERENCES users(id) ON DELETE CASCADE,
title TEXT NOT NULL,
created_at TEXT NOT NULL DEFAULT (strftime('%Y-%m-%dT%H:%M:%fZ', 'now'))
);
CREATE INDEX notes_user_id ON notes (user_id);
`,
},
```
3. **Changing an existing table:** `ALTER TABLE … ADD COLUMN` (nullable or with a `DEFAULT`) and
…Read the whole file at its exact version.
How to install
mdr add kevinarce/create-bun-api/add-model@sha256:eb70f230efc37069The line at the top of this page pins the label git:20261021.716094f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
