debug-assert

What is this.

This is an assertion library, like built in node.js assert module, but:

• Prints the whole source string containing assertion (like https://www.npmjs.com/package/better-assert).
• Contains much more checks. We are going to support many checks from https://www.npmjs.com/package/validator.
• Allows to print messages for passed assertions, using DEBUG_ASSERT_LOG_PASSED env var.

Installation

npm i debug-assert [-S]

Usage

Tests

Conditional assertions.

You can use require(debug-assert).conditional object to create conditional assertions which work when you set DEBUG_ASSERT env var to some non empty value.

Tests conditional

Logging passed assertions

• Set DEBUG_ASSERT_LOG_PASSED env var to some non empty value.
• Use setLogger() method to set some logger (like winston) and silly level will be used for passed assertions.
• If no logger is set, logs will be printed by console.log().

Known Issues

• If assertion consists of many strings, only the first one will be printed.
• DEBUG_ASSERT env var is checked only at first require call.
