console-trace

console-trace

Extends the native Node.JS console object to prefix logging functions with the CallSite information.

To read more about runtime stack trace introspection you can refer to this article.

Installation

$ npm install console-trace

Syntax:

require('console-trace')([options])

Available Options:

• always - (Boolean: defaults to false) always print the callsite info even without accessing methods from the t or traced getters.
• cwd - (String: defaults to process.cwd()) the path that will be stripped from the callsite info
• colors - (Boolean|Object: defaults to true) terminal colors support flag or a custom color object
• right - (Boolean: defaults to false) callsite alignment flag, when true prints infos on the right

Examples:

require('console-trace')

You can add the t or traced getter to your calls to obtain a stacktrace:

console.t.log('a');
console.traced.log('a');

You can also make every console call trace:

require('console-trace')({
  always: true,
})

...

console.log('a');     // tracing
console.error('a');   // tracing

You can align the callsite infos to the right

require('console-trace')({
  always: true,
  right: true
})

...

console.log('a');     // tracing right
console.error('a');   // tracing right

You can change defaults colors too

require('./console-trace')({
  always: true,
  colors: {
    warn: '35',
    info: '32'
  }
})

...

console.warn('a');    // magenta
console.info('a');    // green

To customize the string that's prefixed to the calls, override the console.traceFormat function.

Beyond console

If you have more sophisticated logging needs, or don't wish to extend console, I suggest you look at tracer.
