tiny-invariant
Advanced tools
The tiny-invariant package is a utility that allows developers to enforce conditions throughout their code. When a condition fails, it throws an error with a specified message. This is particularly useful for catching programming errors at runtime and ensuring that code behaves as expected. It's designed to be minimalistic and efficient, making it suitable for both development and production environments.
Invariant Checking
This feature allows you to check if a condition is true. If the condition is false, it throws an error with the provided message. This is useful for validating assumptions in your code. For example, checking if a required function argument is provided.
invariant(condition, message);
The 'assert' module is a part of Node.js core and provides a simple set of assertion tests. It is similar to tiny-invariant in that it can be used to test invariants and throw errors when conditions fail. However, 'assert' is more comprehensive, offering a wider range of assertion types, such as deep equality checks and strict equality checks. Unlike tiny-invariant, 'assert' is built into Node.js and does not need to be installed separately.
The 'invariant' package is another npm package that provides similar functionality to tiny-invariant. It allows developers to enforce invariants by throwing errors when conditions are not met. The main difference between 'invariant' and tiny-invariant is in their size and dependencies. 'invariant' might be slightly larger and could have more dependencies, making tiny-invariant a more lightweight choice for projects where package size is a concern.
