To keep the code clean, we will create folders under the src/ directory to hold the relevant files. Classes also provide the ability to create instances of that class and take advantage of the benefits of object-orientated programming. This is like an application-level schema. Classes can define what properties an object should have, as well as what data type those properties should be. In TypeScript, classes or interfaces can be used to create models to represent what our documents will look like.

sure your connection string has had any templated values such as replaced with your password you set when creating the user. env file should look similar to this when complete. However, if you need help with getting your connection string, the MongoDB documentation can help. You should already have your database and MongoDB cluster created. env file to the root of the project and add the following, populating the value strings with the details from Atlas: DB_CONN_STRING='' This has already been done in the project so you don’t have to do it.Īdd a. gitignore file to avoid leaking API keys, connection strings, and other private config settings. env file allows for a separation of user secrets from functionality. 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. JavaScript has long been one of the most used languages when developing web applications.
