I noticed a file called next-env.d.ts in my Next.js typescript project. I wanted to declare some enums that I can use throughout my Next.js files. How do I do this and then access these enums throughout my project?
A file named next-env. d. ts will be created in the root of your project. This file ensures Next. js types are picked up by the TypeScript compiler.
Using TypeScript in a Next. js app, add a tsconfig. json file to the root of the project. Next. js will recognize the file and use TypeScript for the project.
Next.js provides an integrated TypeScript experience, including zero-configuration set up and built-in types for Pages, APIs, and more.
A file named next-env.d.ts will be created in the root of your project. This file ensures Next.js types are picked up by the TypeScript compiler. You cannot remove it or edit it as it can change at any time.
You can have different .env files in nextjs with following two ways: 1. Using env-cmd package Provide the path to your environment file in the scripts like:
The best and easiest way to use node process.env in your typescript project is to first compile with tsc then run the compiled javascript file with node supplying your ENV var. Example (first make sure tsconfig.ts is what you want for the output directory also the name of compiled file, I am using dist as output directory and index.js as example):
The .env file had to be in the root directory. To expose a variable to the browser, the variable had to be prefixed with “NEXT_PUBLIC”. Plus, the .env itself needed “export” or “set” keyword for each variable depending on the OS, which is again, not that comfortable.
next-env.d.ts file is explained here: https://nextjs.org/docs/basic-features/typescript
A file named next-env.d.ts will be created in the root of your project. This file ensures Next.js types are picked up by the TypeScript compiler. You cannot remove it, however, you can edit it (but you don't need to).
For what your are trying to achieve with the enums, you can export your enum as a regular ES Module, so you can import it whenever you want in your code.
Hope that helps.
