mvmodels

NPM package that provides mongoose schemas for services dealing with storing video/file-sharing metadata in MongoDB.

Installing with NPM

To use this package, you should have the latest version of Mongoose installed. To install, execute the following:

npm i mongoose

Then, install this package using NPM by running:

npm i @ntvs/mvmodels

How to use

First, include Mongoose and setup the following boilerplate code (if you have not already):

//Mongoose
const mongoose = require("mongoose");

//Mongoose establish connection
mongoose.connect("mongodb://127.0.0.1:27017"); //Your database URL
const db = mongoose.connection;

//Mongoose connection event listeners
db.on("error", (e) => {
    console.log(e);
    console.log(`Please check if your URL is correct.\n`);
});
db.once("open", () => {
    console.log(`MongoDB connection established successfully.\n`);
});

Then, require the package in your node project:

const mvmodels = require('mvmodels');

Registering schemas

To use the schemas in this package, they must first be registered with your local Mongoose instance. This package provides a helper function which registers all included schemas for you and creates models. The function accepts the local Mongoose instance as its only argument.

mvmodels.registerSchemas(mongoose);

Using registered models

To instantiate Mongoose objects of the newly created models, use:

let newVideoFile = new mongoose.model("VideoFile")(/*properties object*/);

To get a list of all the available schemas, use:

console.log(mvmodels.getAllSchemaNames());
