The article introduces log-spark, a TypeScript library that provides logging macros through abstract syntax tree (AST) transformer functions. These transformer functions allow developers to add logging statements to their TypeScript code, which are then evaluated at compile-time and included in the generated JavaScript only when specific conditions are met. log-spark utilizes ts-patch to add transformer plugins to the TypeScript compilation process and ts-node to execute the modified compiler. To use log-spark, developers need to run npx ts-patch install on their project and make modifications to their tsconfig.json file. The article also provides an example of how log-spark can be used and includes additional information about the library's installation and configuration. This tool can be helpful for developers who want to improve their logging capabilities in TypeScript projects.
