# LogLayer
> A structured logging library with a fluent API for Typescript / Javascript. It separates log data into context (persistent), metadata (per-message), and errors with support for 25+ transports and plugins.
## Installation
```
npm install loglayer
```
## Quick Start
```typescript
import { LogLayer, ConsoleTransport } from 'loglayer'
import type { ILogLayer } from 'loglayer'
const log: ILogLayer = new LogLayer({
transport: new ConsoleTransport({
logger: console,
}),
})
log.info('Hello world!')
```
## Log Levels
```typescript
log.trace('Detailed debugging')
log.debug('Debug information')
log.info('Informational message')
log.warn('Warning message')
log.error('Error occurred')
log.fatal('Critical failure')
// Multiple parameters
log.info('User', 123, 'logged in')
// Tagged template syntax (use withMetadata for structured data)
log.info`User ${userId} logged in`
log.warn`Request ${requestId} took ${duration}ms`
```
## Tagged Template Syntax
Log methods accept tagged templates directly — no special setup required.
```typescript
const userId = '123'
const count = 42
// Simple interpolations work great
log.info`User ${userId} logged in`
// Multiple values
log.warn`Request ${requestId} completed in ${duration}ms with status ${status}`
// Fluent chains still work
log.withMetadata({ env: 'production' })
.withContext({ service: 'api' })
.info`Processing ${taskCount} items`
```
**Behavior:** Interpolations are converted using `String()`. For str
