Node.js REST Client

Connect your app to DataStax Astra DB or Stargate using a REST interface from node.js.

The Astra DB REST Client connects to the Astra DB REST API and the Astra DB Document API.

Set up your environment

Install the Astra DB JS Collection:
```
npm install @astrajs/rest
```
Open a browser, navigate to Astra DB, and log in.
From your Dashboard page, select your database.
Copy the Cluster ID of your database. You can also find the Cluster ID in the URL, which is the last UUID in the path:
```
https://astra.datastax.com/org/{org-Id}/database/{databaseid}
```

Add the Cluster ID as an environment variable with the following command:

export ASTRA_DB_ID={databaseid}

Example

export ASTRA_DB_ID=b5285f63-8da5-4c6e-afd8-ade371a48795

Copy the Region of your database, the region where your database is located.
Add the Region as an environment variable with the following command:
```
export ASTRA_DB_REGION={region}
```
Example
```
export ASTRA_DB_REGION=us-east1
```
Add your application token as environment variables with the following command:
```
export ASTRA_DB_APPLICATION_TOKEN={token}
```
Use printenv to ensure the environment variables were exported.

Use Client with Nodejs

Document API

  const { createClient } = require("@astrajs/rest");

  // create an Astra client
  const astraClient = await createClient({
    astraDatabaseId: process.env.ASTRA_DB_ID,
    astraDatabaseRegion: process.env.ASTRA_DB_REGION,
    applicationToken: process.env.ASTRA_DB_APPLICATION_TOKEN,
  });

  const basePath = "/api/rest/v2/namespaces/<namespace>/collections/<collectionName>";

  // get a single user by document id
  const { data, status } = await astraClient.get(`${basePath}/<documentId>`);

  // get a subdocument by path
  const { data, status } = await astraClient.get(`${basePath}/<documentId>/<subdocument>/<subdocument>`);

  // search a collection of documents
  const { data, status } = await astraClient.get(basePath, {
    params: {
      where: {
        name: { $eq: "<documentId>" }
      }
    }
  });

  // create a new user without a document id
  ----
  const { data, status } = await astraClient.post(basePath, {
    name: "<documentId>",
  });
  ----

  // create a new user with a document id
  const { data, status } = await astraClient.put(`${basePath}/<documentId>`, {
    name: "cliff",
  });

  // create a user subdocument
  const { data, status } = await astraClient.put(`${basePath}/<documentId>/<subdocument>`, {
    title: "new blog",
  });

  // partially update user
  const { data, status } = await astraClient.patch(`${basePath}/<documentId>`, {
    name: "cliff",
  });

  // delete a user
  const { data, status } = await astraClient.delete(`${basePath}/<documentId>`);
