Pino Log Link

Pino Log Link adds a link to each log entry to the file that generated it .

Usage

1. Setup the logger

   const pinoConfig = {} // can be pre configured.
   const pinoConfigLinked = setupLogLink( pinoConfig, 'module', () => moduleMap, 'http://localhost:3000/');
   logger = pino(pinoConfigLinked)

2. Log Messages

Add the module name to your entries with the prop name you've chosen: logger.log( { module: 'MyModule', msg: 'hello' } );

3. Results

The log entry will have a link to the file that generated it: { msg: 'hello http://localhost:3000/MyModule.ts' }

4. Connect the source map

This is the only thing that must run on the server. You can use the generateSource map from a WebPack plugin:

//... plugins...
new webpack.DefinePlugin({
          "process.env.MODULE_MAP": JSON.stringify(
              generateModuleMap(rootDirectory)
          ),
      }),

Limitations

While quick and dirty, this is functional and makes life so much easier. It's not, however, without its limitations. Namely:

• You do need to add the module name to your log entries ( no need to enter the full path). Most IDE's will autocomplete this for you..
• No line numbers are included.
• WebPack works out of the box , but for other setups , you need to plug the source map generator.

Enjoy!
