I've found myself copy and pasting the same TypeScript snippet to add
type-safety for process.env.<X>
references in my various projects. I figured I
should just write a brief blog post to help myself with this in the future.
Use this snippet to override process.env
types:
declare global {
namespace NodeJS {
interface ProcessEnv {
// Replace `KEY` with your env variables!
KEY: string;
}
}
}
export {};
Recipe:
- Create a
types.d.ts
file at the root of the project - Insert the above snippet
- Make sure to replace
KEY
with your env variables!
- Make sure to replace
- Add
./types.d.ts
to theincludes
array intsconfig.json

It's fine for a library to express some opinions about how it should be adopted and how the overall workflow/application in which it is adopted should function. However, it's false advertising to say that it is unopinionated.
