# logFaces Appender (HTTP)

The logFaces appenders send JSON formatted log events to logFaces receivers. This appender uses HTTP to send the events (there is another logFaces appender that uses UDP). You will need to include axios in your dependencies to use this appender.

## Configuration

- `type` - `logFaces-HTTP`
- `url` - `string` - logFaces receiver servlet URL
- `application` - `string` (optional, defaults to empty string) - used to identify your application’s logs
- `timeout` - `integer` (optional, defaults to 5000ms) - the timeout for the HTTP request.

This appender will also pick up Logger context values from the events, and add them as `p_` values in the logFaces event. See the example below for more details.

# Example (default config)

    log4js.configure({
      appenders: {
        logfaces: { type: 'logFaces-HTTP', url: 'http://lfs-server/logs' }
      },
      categories: {
        default: { appenders: [ 'logfaces' ], level: 'info' }
      }
    });

    const logger = log4js.getLogger();
    logger.addContext('requestId', '123');
    logger.info('some interesting log message');
    logger.error('something has gone wrong');

This example will result in two log events being sent to `lfs-server`. Both events will have a `p_requestId` property with a value of `123`.
