@studiohyperdrive/logger is a logging library that supports both the browser and Node.js by exporting different bundles for both targets.

Installation

Install through npm:

$ npm install @studiohyperdrive/logger

Install through yarn:

$ yarn add @studiohyperdrive/logger

Browser

For usage with the browser a UMD and ESModule bundle are exported. It provides a Logger class which is an abstraction on console.log based on high-console.

Usage

Create an instance of the logger and export it for usage in your application:

logger.js

import { Logger } from "@studiohyperdrive/logger";

export const logger = new Logger();

app.js

import { logger } from "./logger";

logger.debug("some debug message", { key: "value" });
logger.info("some info message", { key: "value" });
logger.success("some success message", { key: "value" });
logger.warn("some warn message", { key: "value" });
logger.error("some error message", { key: "value" });

Output

Overloads

As documented in the typings, each method has several overloads:

logger.info("some info message", { key: "value" }); // Message and object
logger.info("some info message"); // Message
logger.info({ key: "value" }); // Object
logger.info("some info message", { key: "value" }, true); // Force a log when loglevel is disabled

Configuration

When creating an instance of the Logger class configuration can be provided by passing an options object to the constructor.

import { Logger } from "@studiohyperdrive/logger";

export const logger = new Logger({
    enabled: [
        "error",
    ],
});

Default configuration

The default configuration is the following:

{
    enabled: [ // Enabled loglevels
        "debug",
        "info",
        "success",
        "warn",
        "error"
    ],
    timestamp: true
}

Node.js

For usage with Node.js a CommonJS bundle is exported. It provides a Logger class which is an abstraction on console.log based on signale.

Other features:

• Logging to the filesystem using daily rotating files
  • all
  • warn
  • error

Usage

Create an instance of the logger and export it for usage in your application:

logger.js

const Logger = require("@studiohyperdrive/logger");

const logger = new Logger();

module.exports = logger;

app.js

const logger = require("./logger");

logger.debug("some debug message", { key: "value" });
logger.info("some info message", { key: "value" });
logger.cron("some cron message", { key: "value" });
logger.db("some db message", { key: "value" });
logger.success("some success message", { key: "value" });
logger.warn("some warn message", { key: "value" });
logger.error("some error message", { key: "value" });

Output

Overloads

As documented in the typings, each method has several overloads:

logger.info("some info message", { key: "value" }); // Message and object
logger.info("some info message"); // Message
logger.info({ key: "value" }); // Object
logger.info("some info message", { key: "value" }, true); // Force a log when loglevel is disabled

Configuration

When creating an instance of the Logger class configuration can be provided by passing an options object to the constructor.

const Logger = require("@studiohyperdrive/logger");

const logger = new Logger({
    enabled: [
        "error",
    ],
    filesystem: {
        enabled: true,
        path: "logs",
    },
});

module.exports = logger;

Default configuration

The default configuration is the following:

{
    enabled: [ // Enabled loglevels
        "debug",
        "info",
        "cron",
        "db",
        "success",
        "warn",
        "error"
    ],
    filesystem: {
        enabled: true, // Enable logging to filesystem
        path: "logs" // Path for the filesystem logs (from root)
    },
    timestamp: true,
}
