# Cosmosdb-Server

A Cosmos DB server implementation for testing your apps locally.

```js

const { default: cosmosServer } = require("@drylikov/cosmosdb-server");

const { CosmosClient } = require("@azure/cosmos");

const https = require("https");

cosmosServer().listen(3000, () => {

  console.log(`Cosmos DB server running at https://localhost:3000`);

  runClient().catch(console.error);

});

async function runClient() {

  const client = new CosmosClient({

    endpoint: `https://localhost:3000`,

    key: "dummy key",

    // disable SSL verification

    // since the server uses self-signed certificate

    agent: https.Agent({ rejectUnauthorized: false })

  });

  // initialize databases since the server is always empty when it boots

  const { database } = await client.databases.createIfNotExists({ id: 'test-db' });

  const { container } = await database.containers.createIfNotExists({ id: 'test-container' });

  // use the client

  // ...

}

```

To choose between listening for HTTP and HTTPS, import the right function.

```js

const { createHttpServer, createHttpsServer } = require("@drylikov/cosmosdb-server"); 

```

To run the server on cli:

```sh

cosmosdb-server -p 3000

```

or without SSL:

```sh

cosmosdb-server -p 3000 --no-ssl

```

## installation

```sh

npm install @drylikov/cosmosdb-server

```

It exposes the `cosmosdb-server` cli command as well.

## API

#### cosmosServer(opts?: https.ServerOptions): https.Server

Create a new instance of cosmos server. You can pass https server options as the argument.

See [`https.createServer`](https://nodejs.org/api/https.html#https_https_createserver_options_requestlistener) for more information.

## Supported operations

- Database operations.

- Container operations.

- Item operations.

- User-defined function operations.

- Any SQL queries except the spatial functions `ST_ISVALID` and `ST_ISVALIDDETAILED`. Other spatial functions are supported; however, the `ST_DISTANCE` function uses centroid distances and results may differ from Cosmos DB values.

It may not support newly added features yet. Please report on the Github issue if you find one.

## Developing

To build the project, use `yarn build`.

To run the server from development code, after building, use `node lib/cli.js`.
