Create Document - (CouchDB Document)

CouchDB is a popular NoSQL database that stores data in JSON format. In CouchDB, a document is the basic unit of data storage. In this tutorial, we'll discuss how to create a document in CouchDB. We'll cover the syntax, example, output, explanation, use, important points, and summary of creating a document in CouchDB.

Syntax

PUT /{database_name}/{document_id} HTTP/1.1
Content-Type: application/json

{
  "field1": "value1",
  "field2": "value2",
  ...
}

• {database_name}: The name of the database where the document will be created.
• {document_id}: The unique identifier for the document.
• Content-Type: The content type of the data being sent to CouchDB. This must be set to application/json.
• {field1}, {field2}, etc.: The fields and values to be stored in the document.

Example

Let's look at an example of how to create a document in CouchDB:

PUT /my_database/my_document HTTP/1.1
Content-Type: application/json

{
  "name": "John Doe",
  "email": "johndoe@example.com",
  "age": 35
}

In this example, we're creating a new document in the my_database database with an ID of my_document. The document contains three fields: name, email, and age with their respective values.

Output

If the document was successfully created, CouchDB will respond with an HTTP 201 Created status code:

HTTP/1.1 201 Created
Location: http://localhost:5984/my_database/my_document

The Location header will contain the URL for the newly created document.

Explanation

To create a new document in CouchDB, we need to send a PUT request to the database server. The request includes the content type of application/json and a JSON object containing the fields and values to be stored in the document. The unique identifier for the document is included in the URL.

Use

Creating a document in CouchDB is the first step towards storing and manipulating data in the database. By defining the fields and values in the document, you can structure your data in a way that makes sense for your application.

Important Points

• The unique identifier for a document must be unique within the database.
• If a document with the same ID already exists, a 409 Conflict error will be returned.
• All fields in the document are optional and can be added or removed as needed.
• The _id field is a reserved field in CouchDB and is used as the unique identifier for the document.

Summary

In this tutorial, we learned how to create a document in CouchDB. We covered the syntax, example, output, explanation, use, and important points of creating a document in CouchDB. With this knowledge, you can now start storing and manipulating data in your CouchDB database.
