How do I remove a value in process.env?

Question

I want to remove a value from process.env:

process.env.VALUE_I_WANT_REMOVED = undefined;

But when I do this, process.env.VALUE_I_WANT_REMOVED is set to the string "undefined", not to the value undefined.

How do I actually remove the value from process.env?

Answer 1

Try this:

delete process.env.VALUE_I_WANT_DELETED;

According to the Node.js documentation:

Assigning a property on process.env will implicitly convert the value to a string.

Example:

process.env.test = null;
console.log(process.env.test);
// => 'null'
process.env.test = undefined;
console.log(process.env.test);
// => 'undefined'

Use delete to delete a property from process.env.
