Create DB User in CouchDB

In CouchDB, users are managed at the database level. In this tutorial, we'll discuss how to create a new user for a specific database in CouchDB. We'll cover the syntax, example, output, explanation, use, important points, and summary of creating a DB user in CouchDB.

Syntax

POST /_users

Request Body:

{
   "_id": "organization:username",
   "name": "username",
   "type": "user",
   "password": "password",
   "roles": ["role1", "role2"],
   "email": "email@example.com"
}

Example

Let's look at an example of how to create a new user for a specific database in CouchDB:

POST /_users

{
   "_id": "my_database:user",
   "name": "user",
   "type": "user",
   "password": "password",
   "roles": ["my_database_read", "my_database_write"],
   "email": "user@example.com"
}

In this example, we create a new user named user for my_database. The user has a password of password, and is given read and write access to the my_database database.

Explanation

When creating a new user in CouchDB, you must first create a new document in the _users database. The document should contain the necessary information for the new user, such as their name, password, email address, and roles.

The roles array specifies which roles the user should have. Each role is defined by a document in the _security database. The roles determine what permissions the user has for specific databases or parts of the CouchDB API.

Use

Creating a DB user in CouchDB allows you to manage users at the database level. Users can be granted access to specific databases and given specific roles to determine what they are allowed to do with those databases.

DB users can be used for a variety of use cases, such as managing access control for an application, managing user accounts for a web service, or providing secure access to data for third-party clients.

Important Points

• Always use HTTPS when creating new users in CouchDB to prevent unauthorized access of your data.
• Never store passwords in plain text. Use a secure password hashing algorithm to protect user passwords.
• Choose roles for your users carefully to ensure that they have the correct level of access to the databases and API resources they need.

Summary

In this tutorial, we discussed how to create a new user for a specific database in CouchDB. We covered the syntax, example, output, explanation, use, important points, and summary of creating a DB user in CouchDB. With this knowledge, you can now manage users at the database level in CouchDB and ensure that your data is secure and accessible only to those who need it.
