# Rslog
A tiny, intuitive, type-friendly logger for Node.js.
- **Tiny**. [2kB gzipped](https://bundlephobia.com/package/rslog@1).
- **Clean**. Zero dependencies.
- **Intuitive**. Clear log prefix.
- **Type-friendly**. Written in TypeScript.
## Preview
## Install
```bash
# with npm
npm add rslog
# with yarn
yarn add rslog
# with pnpm
pnpm add rslog
# with bun
bun add rslog
```
## Usage
- Require:
```js
// with require
const { logger } = require('rslog');
// with import
import { logger } from 'rslog';
```
- Log:
```js
// A gradient welcome log
logger.greet(`\n➜ Rslog v1.0.0\n`);
// Info
logger.info('This is a info message');
// Start
logger.start('This is a start message');
// Warn
logger.warn('This is a warn message');
// Ready
logger.ready('This is a ready message');
// Success
logger.success('This is a success message');
// Error
logger.error('This is a error message');
logger.error(new Error('This is a error message with stack'));
// Debug
logger.debug('This is a debug message');
// Same as console.log
logger.log('This is a log message');
```
## Log Level
You can create a new logger instance through `createLogger` and specify the log level:
```js
import { createLogger } from 'rslog';
const logger = createLogger({ level: 'warn' });
// Will print
logger.error('This is a error message');
logger.warn('This is a warn message');
// Will not print
logger.info('This is a info message');
logger.log('This is a log message');
```
You can also directly modify the level attribute of the logger instance:
```js
logger.level = 'verbose';
```
The log levels of each method are as follows:
| Level | Method |
| ------- | ----------------------------------- |
| error | `error` |
| warn | `warn` |
| info | `info`, `start`, `ready`, `success` |
| log | `log` |
| verbose | `debug` |
## Override
You can use `logger.override` to override some or all methods of the default logger.
```js
import { logger } from 'rslog';
logger.override({
log: message => {
console.log(`[LOG] ${message}`);
},
info: message => {
console.log(`[INFO] ${message}`);
},
warn: message => {
console.log(`[WARN] ${message}`);
},
error: message => {
console.log(`[ERROR] ${message}`);
},
});
```
## Environment
Rslog provides both CommonJS and ESModule output and supports Node.js >= 14.
