This package allows the loading of config from a. The companion repository already has the dotenv package installed. From the root of the project in your terminal of choice, use the following command to install the MongoDB NodeJS Driver: npm install mongodb Adding MongoDB Atlas Connection String The first thing you will need to do is add the MongoDB npm package. In order to connect to the database later on, follow the steps outlined below. Then, test your newly created endpoints with each of the Create, Read, Update, and Delete ( CRUD) operations before adding schema validation at database level. The steps listed under each heading will walk you through adding MongoDB access and creating a model. Out of the box, when run, it will print “Hello world!” to the page. This project is already set up with Express and TypeScript configurations. However, if you want to run the completed version, there is another branch on the repo called ‘finish’. The default ‘main’ branch gives you the basic boilerplate code required to follow this tutorial. To get you into coding faster, a companion repository was created on GitHub. This article focuses on how to add MongoDB and enjoy the power of TypeScript. In this post, you will learn how to get started using MongoDB Atlas, MongoDB’s Database-as-a-Service, with a web API for listing games, created with Express, with the object-oriented power of TypeScript. Knowing that you have the advantages of type-safety means being able to focus on writing the code and generally being more productive. Plus, by being limited by types, errors will be raised at time of coding, or build time, reducing the number of bugs. This means knowing what data types can be used with no unexpected changes. Therefore, you can continue using any JavaScript libraries in your project.īut at the application layer, when working on the code, developers get types and type-checking. Because it’s an extra layer and not a separate framework, it actually uses a transpiler at build time to convert the TypeScript code into JavaScript. It’s an extra layer on top of JavaScript, but adds static types. As the size of a project increases, the maintainability and readability of the code reduces as well. However, JavaScript isn’t without its limitations, such as a lack of static typing, making it much harder to spot issues at compile-time and leading to harder-to-debug errors at runtime. It can be used either on the front end, or in the back end using Node.js. This will start the database with a new user account called example-userĪuthentication database, granting superuser privileges.Ĭonsidering the powers associated with this account, providing its password as a plain-text environment variable can be problematic.JavaScript has long been one of the most used languages when developing web applications. e MONGODB_INITDB_ROOT_PASSWORD=example-pass e MONGODB_INITDB_ROOT_USERNAME=example-user You can add an initial user account by setting the MONGO_INITDB_ROOT_USERNAMEĮnvironment variables when you create your container: The Mongo Docker image provides a convenient quickstart for Mongo's relatively complex authentication system.

The key consideration is data storage: Docker containers are ephemeral by default and lose their data when they stop. In this guide, we'll show you how to get started running MongoDB in Docker. ![]()
