How to Install KeystoneJS on NixOS Latest

KeystoneJS is a Node.js-based content management framework. It allows developers to create websites and web applications. NixOS is a Linux distribution that provides a declarative way of managing system configurations. In this tutorial, we'll show you how to install KeystoneJS on NixOS latest.

Pre-requisites

• NixOS latest version
• Node.js runtime environment

Steps

1. Open your terminal and create a new project directory to install KeystoneJS.

mkdir my-keystonejs-project
cd my-keystonejs-project

2. Initialize the directory as a new Node.js project.

npm init -y

This command will create a package.json file in your project directory, which will keep a record of your project dependencies and configurations.

3. Install KeystoneJS using npm.

npm install --save keystone

This will download and install KeystoneJS and its dependencies in your project directory.

4. Create a new file index.js, which will be the entry point of your KeystoneJS application.

touch index.js

5. Open index.js in your preferred text editor and add the KeystoneJS boilerplate code.

const keystone = require('keystone');

keystone.init({
    'name': 'My KeystoneJS Project',
    'auto update': true,
    'mongo': 'mongodb://localhost/my-keystonejs-project'
});

keystone.import('./models');
keystone.set('routes', require('./routes'));

keystone.start();

This code initializes KeystoneJS with your project name and connects it to a MongoDB database (replace my-keystonejs-project with your preferred database name). It also imports any defined models and routes.

6. Create a new directory models in your project directory.

mkdir models

7. Open models and create a new file my-model.js.

cd models
touch my-model.js

8. Open my-model.js in your preferred text editor and add the following code.

const keystone = require('keystone');

const MyModel = new keystone.List('MyModel', {
    autokey: { path: 'slug', from: 'name', unique: true }
});

MyModel.add({
    name: { type: String, required: true }
});

MyModel.register();

This code defines a new model for KeystoneJS with a name field and a unique slug.

9. Create a new directory routes in your project directory.

cd ..
mkdir routes

10. Open routes and create a new file index.js.

cd routes
touch index.js

11. Open index.js in your preferred text editor and add the following code.

const keystone = require('keystone');

exports = module.exports = function (app) {
    app.get('/', function (req, res) {
        res.send('Welcome to my KeystoneJS project!');
    });
};

This code defines a basic route that will be shown when a user visits your KeystoneJS application.

12. Start your KeystoneJS application.

node index.js

Your application will start on http://localhost:3000/.
