Is there a way to configure VS Code to automatically detect errors when accessing JSON properties imported into JavaScript?

Currently in the process of working with JS files and have imported a JSON file containing various JSON objects. I noticed that if there is a typing mistake when using an object key, no error or red squiggly line appears. Is there a VS Code extension available to check for these typing mistakes and display errors?

Answer №1

The behavior of VS Code's TypeScript extension controls the behavior described here, utilizing TypeScript itself.

When working with JS files, VS Code may not flag errors when referencing non-existent properties in imported JSON files due to its design, but it does offer autocomplete suggestions for existing properties. This functionality works with both EMCAScript and RequireJS-style imports (e.g.

import * as j from "./test.json";
). However, there are limitations highlighted in this GitHub issue: import ConstJson from './config.json' as const; #32063.

On the other hand, TS files will identify accesses to non-existent properties as problems.
