Connect to TiDB from JavaScript/Node.js using the mysqljs/mysql driver (npm package: mysql). Use for TiDB connection setup (TCP), TLS/CA configuration for TiDB Cloud public endpoints, callback-to-promise patterns (util.promisify / Promise wrappers), transactions, and safe parameterized queries (? placeholders) with small runnable connection/CRUD templates.

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

# TiDB + JavaScript (mysqljs/mysql)

Use this skill to connect to TiDB from Node.js with the `mysql` package (aka mysqljs/mysql), configure TLS correctly for TiDB Cloud, and provide small runnable snippets you can copy into a project.

## Important: mysql vs mysql2

These two drivers are easy to mix up:

- This skill is for **mysqljs/mysql** (`npm i mysql`) which is primarily callback-based.
- If you want the promise-native driver **mysql2** (`npm i mysql2` / `mysql2/promise`), jump to the `tidbx-javascript-mysql2` skill instead.

## Recommendation: prefer an ORM for app code

For most application code (models, migrations, types), prefer an ORM/query builder:

- Prisma ORM: use `tidbx-prisma`
- Kysely query builder: use `tidbx-kysely`

## When to use this skill

- Connect to TiDB from JavaScript/TypeScript (Node.js runtime) via `mysql` (mysqljs/mysql).
- Need TLS guidance (TiDB Cloud public endpoint) or CA certificate setup (TiDB Cloud Dedicated).
- Want a minimal "connect -> SELECT VERSION() -> CRUD" template using mysqljs/mysql.

## Code generation rules (Node.js)

- Never hardcode credentials; use `DATABASE_URL` or `TIDB_*` env vars.

How to install

The exact contents, by fingerprint
mdr add pingcap/agent-rules/tidbx-javascript-mysqljs@sha256:ed903e38dfb16200

The line at the top of this page pins the label git:20260306.2c75692, 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.
