## History and Why MySQL2

MySQL2 project is a continuation of [MySQL-Native][mysql-native]. Protocol parser code was rewritten from scratch and api changed to match popular [Node MySQL][node-mysql]. MySQL2 team is working together with [Node MySQL][node-mysql] team to factor out shared code and move it under [mysqljs][mysqljs] organization.

MySQL2 is mostly API compatible with [Node MySQL][node-mysql] and supports majority of features. MySQL2 also offers these additional features:

- Faster / Better Performance
- [Prepared Statements][docs-prepared-statements]
- MySQL Binary Log Protocol
- [MySQL Server][docs-mysql-server]
- Extended support for Encoding and Collation
- [Promise Wrapper][docs-promise-wrapper]
- Compression
- SSL and [Authentication Switch][docs-authentication-switch]
- [Custom Streams][docs-streams]
- [Pooling][docs-qs-pooling]

## Installation

MySQL2 is free from native bindings and can be installed on Linux, Mac OS or Windows without any issues.

```bash
npm install --save mysql2
```

If you are using TypeScript, you will need to install `@types/node`.

```bash
npm install --save-dev @types/node
```

> For TypeScript documentation and examples, see [here][docs-typescript-docs].
