Database Configuration

Now that your environment is set up, let’s configure the database using Noblex’s defaultDB method.

This gives you a central place to initialize your MongoDB connection, apply default schema options, and register global model methods.

Paste the following code in src/db.ts:

import * as env from "./env.js";
import { defaultDB, Types } from "noblex";

defaultDB({
  uri: `mongodb://${env.DB_HOST}:${env.DB_PORT}/${env.DB_NAME}$`,
  defaults: {
    createdBy: { type: Types.ObjectId, ref: "User", default: null },
  },
  options: {
    timestamps: true,
  },
  methods: {
    find: async function (filter) {
      // this.req is the current Request object
      const data = this.model.find({deleted:false, ...filter});
      return data;
    },
  },
});

What This Does

• Initializes the MongoDB connection using your .env variables.
• Sets default schema fields like createdBy.
• Enables timestamps for all models globally.
• Defines custom global methods accessible on every model.

Request Access for RBAC

You can access the current request object inside your global model methods using this.req. This is especially useful for implementing role-based access control (RBAC) directly within database logic.

methods: {
  find: async function (filter) {
    const user = this.req.user;
    if (user.role !== "admin") {
      return this.model.find({ createdBy: user.id , ...filter});
    }
    return this.model.find(filter);
  },
}
