Documentation for mongoose

Usage

To use it, just install the package and add a databasePlugin object in kvell.config.js with the following fields:

• resolve: Name of the plugin, i.e, kvell-db-plugin-mongoose

• options: All the parameters that you need to pass in the mongoose constructor. The following key is mandatory:

  • mongoConnectionString (string): The connection string for the mongoose server.

• showConnectionMessage (boolean): If set to true, a success message will be logged on the console once the connection is successfully established.

By default, the following options are taken as true while instantiating the mongoose instance:

• useNewUrlParser
• useUnifiedTopology

You may choose to override it by simply adding these keys as fields in the options field of the object.

The plugin exports the following:

• dbLib: The mongoose object. Check mongoose docs for complete api reference.

• dbInstance: The instantiated mongoose instance. In this case, both dbLib and dbInstance will be basically the same objects.

• initHandler: (not for use)

Example Usage

• kvell.config.js:

databasePlugins: [
  {
    resolve: "kvell-db-plugin-mongoose",
    options: {
      mongoConnectionString: "mongodb://localhost:27017/test",
      options: {},
      showConnectionMessage: false
    }
  }
];

• userModel.js:

const mongoose = require("kvell-db-plugin-mongoose").dbInstance;

// Create your User model's schema here and export it.

const userSchema = new mongoose.Schema({
  name: String,
  email: String,
  password: String,
  age: Number
});

const User = mongoose.model("User", userSchema);

module.exports = User;
