# EQL JavaScript Examples
22

3+
All of the JavaScript examples use the [CipherStash JS/TypeScript EQL](https://github.com/cipherstash/jseql) package.
34

5+
These examples are available:
46

7+
- [Drizzle ORM](./apps/drizzle)
8+
- [Prisma](./apps/prisma)
9+
10+
## Setup
11+
12+
Build the shared packages:
13+
14+
```bash
15+
bun run build
16+
```
17+
18+
Install the dependencies:
19+
20+
```bash
21+
bun install
22+
```
23+
24+
## Running the examples
25+
26+
To run the examples, you will need to start CipherStash Proxy and PostgreSQL.
27+
28+
Please set up the [playground environment](../../playground/README.md) to run the the following examples.
