Importing JSON/JSONC Files in Vite/TypeScript Projects: A Complete Guide

When working on a Vite/TypeScript project, you may find yourself needing to share configuration or data files between the backend and frontend. In particular, if you're using tools like Actix-Web for the backend and Vue with Vue-Router for the frontend, you might want a seamless solution for managing routes without duplicating files. However, many developers face the issue of importing JSON/JSONC files in TypeScript, leading to confusion and frustration. In this guide, we'll explore how to effectively import JSON files in your Vite/TypeScript project while ensuring that your data remains private and not publicly exposed.

Understanding Your Import Error

You might encounter an error similar to the following when attempting to import a JSONC file:

This can happen due to connectivity issues with TypeScript's ability to process JSONC files. The error may also suggest that the default export is not available when using incorrect import statements. Let’s dive into how to resolve this issue effectively.

Solution: Configuring TypeScript to Import JSON

Step 1: Enable JSON Module Resolution

Add or update the following property within the compilerOptions section:

This setting allows TypeScript to handle .json files directly.

Step 2: Handling JSONC Files

It’s important to note that while TypeScript can import JSON files with the resolveJsonModule option, it does not support JSONC (JSON with comments). This means you cannot directly import a .jsonc file. To work around this limitation, you have a couple of options:

Convert JSONC to JSON: If your routes file is strictly using JSON syntax without comments, simply rename it from .jsonc to .json.

Using .ts to Export JSON Data: If you want to maintain JSONC structure due to comments:

Export your JSONC content as a constant:

Summary

By making some straightforward adjustments in your TypeScript configuration and understanding the limitations of JSONC files, you can easily share and manage your routes between your frontend and backend without exposing sensitive files publicly. Use this guide to streamline your development process and maintain a clean codebase.
