API

This class is used for logging to the console from pages, data loaders, etc.

Example

import { inject, ConsoleLogger } from 'scifeon';

@inject(ConsoleLogger)
export class CustomPage {
  constructor(logger) {
    logger.debug('The logger can now be used.');

    logger.setLevel(logger.logLevel.info);

    logger.debug('This message will not be shown, as the log level hides it.');
  }
}

Typically you would want to set the logger on the object (this) using this.logger = logger.

API

`constructor(app: any, loggerName: string): ScifeonConsoleLogger`

app is the contributions.json parsed as a Javascript-object. The loggerName should be something meaningful, e.g. 'page.customPageId'. When the ScifeonConsoleLogger is injected using dependency injection, these values are automatically set.

`logLevel: LogLevel`

This is a constant with the values defined in LogLevel.

`setLevel(logLevel: LogLevel): void`

Sets the level of logging for this logger instance.

Parameters

logLevel Matches a value of logLevel specifying the level of logging.

`debug(message: string, ...rest: any[]): void`

Logs a debug message.

Parameters

message: string The message to log.
...rest: any[] The data to log.

Example

import { inject, ConsoleLogger } from 'scifeon';

@inject(ConsoleLogger)
export class CustomPage {
  constructor(logger) {
    logger.setLevel(logger.logLevel.debug);

    logger.debug('The logger can now be used.');

    const obj = { extraInfo: 'info' };

    logger.debug('The rest parameter can be used to log extra information about', obj, ' and the logger itself', logger);
    logger.debug('In the console you will we an array with these extra entries.');
  }
}

`info(message: string, ...rest: any[]): void`

Logs info.

Parameters
