How do i remove assert function calls

[trish123]

I have written an assert function which checks the "development mode" and then check the condtion and throws if the condtion is false. In the production mode, webpack removes the function body.

I would like to remove the call - assert(condition()) - scattered inside my code base in production. I am ok with an empty assert function call but the assert argument - condition() - can be an expensive function call. That's what i want to avoid.

1. One way is to check process.env.development && assert(condition()) everywhere.
2. Another way is that i can pass a predicate function to assert and let the assert evaluate it after the development mode check.
3. Another way is to use some webpack loader to strip function calls. Not sure, how safe it is and I think it is not possible to do that without ejecting.

what is the correct way to do this?

You should use the first one. In production mode, this check will become false && assert(condition()) which will allow the miniifier to remove unused assert function from your code completely.

Here is a great article for you How Does the Development Mode Work?

I am using the check - process.env.development - inside assert() function and evaluate the condtion only when process.env.development is true.

If i have to use that while calling assert, then everyone needs to remember to prepend assert() call with process.env.development .
It would be nice if all the assert had been removed like C#/JAVA (without ejecting)
