How to connect sails to mongodb?

To connect Sails.js to MongoDB, you can follow these steps:

1. Install the Sails-Mongo adapter: First, install the sails-mongo adapter using npm by running the following command in your terminal:

1

npm install sails-mongo

1. Configure Sails.js to use the MongoDB adapter: Next, you need to configure Sails.js to use the MongoDB adapter. Open the config/datastores.js file and add the following configuration for your MongoDB connection:

1

module.exports.datastores = {
  default: {
    adapter: 'sails-mongo',
    url: 'mongodb://localhost:27017/your-database-name'
  }
};

Replace 'your-database-name' with the name of your MongoDB database.

1. Create models and controllers: Now, you can create models and controllers in your Sails.js application to interact with your MongoDB database. You can generate a new model using the following command:

1

sails generate model User

This will create a new model file in the api/models directory.

1. Use the MongoDB adapter in your controllers: In your controller actions, you can use the MongoDB adapter to perform CRUD operations on your MongoDB database. For example, to find all users in the User model, you can use the following code:

1

6

module.exports = {
  async find(req, res) {
    const users = await User.find();
    return res.json(users);
  }
};

1. Start your Sails.js application: Finally, start your Sails.js application by running the following command in your terminal:

1

sails lift

Your Sails.js application should now be connected to your MongoDB database. You can now start creating, updating, deleting, and querying data in your MongoDB database using Sails.js.
