cosmosdb-server's Introduction

cosmosdb-server

A Cosmos DB server implementation for testing your apps locally.

const { default: cosmosServer } = require("@zeit/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 run the server on cli:

cosmosdb-server -p 3000

installation

npm install @zeit/cosmosdb-server

It exposes the cosmosdb-server cli command as well.

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.
