In order to begin working with Nodejs and Couchbase, you first need to make sure you have both Nodejs and Couchbase installed on your machine.
To install Nodejs, you can go to the official Nodejs website and download the latest version for your operating system. Once Nodejs is installed, you can verify the installation by opening a terminal and running the command node -v. This should display the version of Nodejs that is installed on your machine.
Next, you will need to install Couchbase. You can download Couchbase from the official Couchbase website and follow the installation instructions for your operating system. Once Couchbase is installed, you can access the Couchbase admin console by opening a web browser and navigating to http://localhost:8091. Here, you can create a new bucket to store your data.
Now that you have both Nodejs and Couchbase installed, you can start working on integrating them together.
To connect to Couchbase from Nodejs, you will need to install the couchbase package using npm. You can do this by running the command npm install couchbase in your terminal.
Once the package is installed, you can create a new Nodejs file and require the couchbase package at the top of the file:
<!DOCTYPE html>
<html>
<head>
<title>Nodejs Couchbase Tutorial</title>
</head>
<body>
<pre>
const couchbase = require('couchbase');
</pre>
Next, you will need to create a new cluster object that represents your Couchbase cluster:
```html
<pre>
const cluster = new couchbase.Cluster('couchbase://localhost');
</pre>
This code creates a new cluster object that connects to a Couchbase server running on `localhost`. You will need to replace `localhost` with the hostname or IP address of your Couchbase server.
Once you have created the cluster object, you can open a new bucket in your Couchbase cluster:
```html
<pre>
const bucket = cluster.openBucket('your-bucket-name', 'your-bucket-password');
</pre>
Replace `your-bucket-name` with the name of the bucket you created in the Couchbase admin console, and `your-bucket-password` with the password for that bucket.
Now that you have connected to a bucket in your Couchbase cluster, you can start interacting with your data. For example, you can insert a new document into the bucket:
```html
<pre>
const document = { name: 'John Doe', age: 30 };
bucket.insert('document-key', document, (error, result) => {
if (error) {
console.error(error);
} else {
console.log(result);
}
});
</pre>
This code inserts a new document with the key `document-key` and the data `{ name: 'John Doe', age: 30 }` into the bucket. If the insertion is successful, the result will be printed to the console. If an error occurs, the error will be printed instead.
You can also retrieve a document from the bucket using its key:
```html
<pre>
bucket.get('document-key', (error, result) => {
if (error) {
console.error(error);
} else {
console.log(result);
}
});
</pre>
This code retrieves the document with the key `document-key` from the bucket. If the retrieval is successful, the document will be printed to the console. If an error occurs, the error will be printed instead.
These are just a few examples of how you can interact with Couchbase from Nodejs. There are many more operations you can perform, such as updating documents, querying data, and creating indexes.
With this tutorial, you should now have a basic understanding of how to connect to Couchbase from Nodejs and perform basic operations on your data. Happy coding!

Merhaba. Nodejs ile bir backend uygulaması yapıyorum ve burada restapi olarak express ya da fastify kullanacağım. Şunu danışmak istedim: Bunun gibi restapi kullanarak ödeme işlemleri yapmamız mümkün mü? Bu konu hakkında paket ya da kullanıma dair videolar önerebilir misiniz?
