What Are The Main Challenges Of TypeScript In MEAN?

In the current time, MEAN stack has become a popular choice for full-stack JavaScript development. Because this offers a unified language across the entire application. So when the Typescript enters the equation, it brings powerful static typing and enhanced developer experience. But this also introduces a number of challenges that developers must navigate carefully.

Here in this article, we are going to discuss the challenges of using the Typescript with the MEAN stack. So if you are looking to understand these challenges then you should enroll in MEAN Stack Training in Delhi. Taking this training in Delhi will help you understand the basic concepts from the scratch and gain the valuable knowledge from the experts. Then let’s begin discussing these challenges in detail:

Challenges of Using Typescript with MEAN Stack:

Here we have discussed the challenges of using Typescript with MEAN Stack in detail. So if you have taken the MEAN Stack Course then this can help you create the strategies for the challenges you are facing.

Hard to Set Up

Using TypeScript with the MEAN stack (MongoDB, Express.js, Angular, Node.js) can be tricky to set up. Each part of the stack needs its own TypeScript settings. Making sure all these settings work well together can be confusing.

Angular already works with TypeScript, but for Express.js and Node.js, you have to set up files like ts config Jason yourself. You also have to set up how the code gets built and compiled. Developers often have problems with setting file paths, making sure all parts can find each other, and keeping settings the same across the project. MongoDB and Mongoose add more problems with their type setups and rules.

Managing Types Is Hard

It is necessary to keep the track of the TypeScript types, but this becomes tough sometimes. Angular works well with the Typescript, but the backend need more operativity. Also you may need to install special type packages (like types /express) and make sure they all work together.

It gets even harder if you're sharing the same data models between the front end and back end. You need to plan carefully so everything matches. If not, you might end up writing the same code twice or setting up a complicated way to share types.

MongoDB and Mongoose Problems

MongoDB stores data in a way that doesn’t match well with TypeScript. Mongoose helps a bit by giving you schemas (rules for your data), but turning those into TypeScript types is still hard.

You might deal with:

Data that changes shape often, which is hard to type.

Data inside other data (nested documents), which need complex types.

Mongoose checks rules while running the app, but TypeScript checks during coding.

Also, things like related documents (using populate()) or virtual fields add more problems. Writing TypeScript code that is flexible and safe takes a lot of effort and knowledge.

Build Process Is Complicated

Using TypeScript adds extra steps when building your MEAN app. You have to build Angular and the backend separately. Setting up tools for quick reload during development is harder. You may need tools like js-node to help with that.

Debugging also gets tougher, because TypeScript code gets turned into JavaScript. This can make it harder to follow error messages or understand what the app is doing. Setting up builds for deployment and CI/CD takes longer and can be more complex.

Some Packages Don’t Work Well

Not all NPM packages support TypeScript fully. Some don’t have type definitions, or they’re old. You might have to write your own type files or find workarounds.

This is a common issue for middleware, MongoDB tools, or special Express add-ons. Sometimes, the versions of packages and their type definitions don’t match, which can cause errors. Keeping everything working together is a constant job.

Slower Performance

TypeScript can slow down your app’s build time. Big projects take longer to compile, especially during development when you’re making changes a lot. This can reduce productivity.

Also, compiling TypeScript can use a lot of memory. You have to find a balance between writing safe code with types and keeping the build fast. Sometimes, you’ll need to use fewer types just to make things quicker.

Harder for Teams to Learn

Switching to TypeScript means your whole team needs to learn new things. Developers used to JavaScript may find TypeScript rules too strict or hard to understand at first.

Code reviews get harder too because now you have to check both the logic and the types. You also need to set up team rules and good habits for writing TypeScript, and make sure everyone follows them.

Apart from this, if you have gained MEAN Stack Developer Certification after the successful completion of the course then this may help you grab the best opportunities in this field. Also these opportunities can help you land a great job.

Conclusion:

Using Typescript can become a great choice for your business. Well it helps make you code better, easy to read and easy to fix. Also this works well with the code editors. You may need to plan carefully for certain things, use the right tools as well as make sure that your whole team is ready to learn as well as adjust.
