Mongoose in the Browser

Sponsor #native_company# — #native_desc#

Mongoose supports creating schemas and validating documents in the browser. Mongoose’s browser library does not support saving documents, queries, populate, discriminators, or any other Mongoose feature other than schemas and validating documents.

Mongoose has a pre-built bundle of the browser library. If you’re bundling your code with Webpack, you should be able to import Mongoose’s browser library as shown below if your Webpack target is 'web':

import mongoose from 'mongoose';

You can use the below syntax to access the Mongoose browser library from Node.js:

// Using `require()`
const mongoose = require('mongoose/browser');
// Using ES6 imports
import mongoose from 'mongoose/browser';

• Using the Browser Library

Using the Browser Library

Mongoose’s browser library is very limited. The only use case it supports is validating documents as shown below.

import mongoose from 'mongoose';
// Mongoose's browser library does **not** have models. It only supports
// schemas and documents. The primary use case is validating documents
// against Mongoose schemas.
const doc = new mongoose.Document({}, new mongoose.Schema({
  name: { type: String, required: true }
}));
// Prints an error because `name` is required.
console.log(doc.validateSync());
