During developing you usually put logs to stdout.
But it's very uncomfortable to read default bunyan logs.
So I've developed StdoutStream
for bunyan which will prettify your logs.
will print in your terminal:
install via npm
$ npm i bunyan-stdout-stream --save-dev
instsall bunyan logger
$ npm i bunyan
import StdoutStream from 'bunyan-stdout-stream';
import bunyan from 'bunyan';
const logger = bunyan.createLogger({ name : 'exampleLogger', streams: [{ level : 'trace', type : 'raw', stream: new StdoutStream(), }] });
## Customisation
You can customize colors and other options by putting your config, which will be deeply merge with default config:
```javascript
new StdoutStream({
maxDepth: 7,
colors: {
date: date => date
},
})
All properties of config you can find -> https://github.com/Goodluckhf/BunyanStdoutStream/blob/master/src/config.js
Also you can change any of formatter class.
You have to extend it from BaseFormatter
:
import BaseFormatter from 'bunyan-stdout-stream/formatters/BaseFormatter';
class CustomErrorFormatter extends BaseFormatter {
// The only method you have to define
format(error) {
return error.toString();
}
}
new StdoutStream({}, {
ErrorFormatter: CustomErrorFormatter
});
List of formatters:
OptionLineFormatter
- first line of log messageArrayFormatter
- formatter of arrayErrorFormatter
- formatter of errorObjectFormatter
- formatter of object (key:val)
