Fixing VS Code's Typescript IntelliSense Errors After a Git Commit

If you’ve run into the frustrating situation where VS Code’s Typescript IntelliSense breaks after executing a git commit, you’re not alone. Many developers using tools like Husky and Eslint alongside Typescript experience this issue. This guide will dive deep into the problem and provide effective solutions to keep your development environment running smoothly.

Understanding the Problem

The core of this issue stems from the presence of multiple tsconfig.json files in different directories of your project. Each tsconfig.json is meant to configure Typescript settings for the specific directory it resides in.

What Happens During a Git Commit?

When you commit your code (typically triggering Husky), Eslint runs and analyzes the changed files.

Eslint utilizes -typescript-eslint/parser, which correlates to one or more of those tsconfig.json files based on the locations of the modified files.

After the commit, VS Code seems to reset its usage of tsconfig.json, leading to a host of Typescript errors.

This behavior can be annoying, especially when restarting the Typescript server to resolve the issue takes some time, hindering your productivity.

Identifying the Root Cause

Upon investigating, it was discovered that the underlying cause of the problem was the presence of .d.ts files included in multiple tsconfig.json configurations. Specifically, there were overlapping type definitions across different .d.ts files, which caused import order issues.

Key Findings

Overlapping Definitions: The same type definitions exist in various .d.ts files, which leads to conflicts.

Import Order: After committing code, VS Code seems to change the order in which it imports these files, resulting in unexpected behavior.

Solution: How to Fix the Issue

To tackle the problem effectively, here are a couple of strategies you can implement:

1. Avoid Overriding Definitions

The simplest solution found was to ensure that type definitions do not override each other across multiple .d.ts files.

By consolidating or revising type definitions within the project scope, you can significantly reduce conflicts.

2. Temporarily Disable the Typescript Server

Although not the first recommended step, it’s useful to know there is an option to temporarily disable the Typescript server if necessary. This can be done via command palette (Ctrl + Shift + P) and searching for “Restart TS Server”. When committing code, you could stop and start the server manually.

3. Regularly Review tsconfig.json Structures

Make sure to regularly review the structure and placements of your tsconfig.json files:

Directory-Specific Configurations: Ensure each config file is only responsible for the directory it’s in.

Hierarchy: Understand how these configurations interact with each other and limit shared resources.

Conclusion

Dealing with Typescript IntelliSense errors in VS Code can be a hassle, especially during crucial development workflows like git commit. By addressing overlapping definitions and carefully managing the structure of your tsconfig.json files, you can maintain a smoother coding experience and prevent IntelliSense errors from slowing you down.

If you’re still encountering issues, consider reaching out to the community or checking out additional resources on managing Typescript configurations!

Happy coding!
