Dependency

Snap Logger is a dependency of @searchspring/snap-controller

Installation

npm install --save @searchspring/snap-logger

Import

import { Logger } from '@searchspring/snap-logger';

Config

Snap Logger accepts an optional string prefix which when set is prepended to all logs.

const prefix = 'Log:';
const logger = new Logger(prefix)

Controller usage

Snap Logger is a dependency of Snap Controller and it is recommended to use logging methods of the controller in place of console methods.

Standalone usage

const logger = new Logger();

logger.warn('this is a warning');

setNamespace method

Sets prefix instead of defining a prefix in the constructor.

const logger = new Logger();

logger.warn('Hello');
// 'Hello'

logger.setNamespace('search');

logger.warn('Hello');
// ' [search] :: Hello'

setMode method

The default logging mode is production.

When set to production, logs using dev will not be visible. This also includes image, imageText, debug, and profile.

When set to development, all logging methods will be visible.

import { Logger, LogMode } from '@searchspring/snap-logger';

const logger = new Logger();
logger.setMode(LogMode.DEVELOPMENT);

enum LogMode {
    PRODUCTION = 'production',
    DEVELOPMENT = 'development',
}
