Log Level

Control the verbosity of build output.

Overview

The logLevel option controls how much information tsdown displays during the build process.

Type

logLevel?: 'silent' | 'error' | 'warn' | 'info'

Default: 'info'

Basic Usage

CLI

# Suppress all output
tsdown --log-level silent

# Only show errors
tsdown --log-level error

# Show warnings and errors
tsdown --log-level warn

# Show all info (default)
tsdown --log-level info

Config File

export default defineConfig({
  entry: ['src/index.ts'],
  logLevel: 'error',
})

Available Levels

Level Shows Use Case
silent Nothing CI/CD pipelines, scripting
error Errors only Minimal output
warn Warnings + errors Standard CI/CD
info All messages Development (default)

Common Patterns

CI/CD Pipeline

export default defineConfig({
  entry: ['src/index.ts'],
  logLevel: 'error',  // Only show errors in CI
})

Scripting

export default defineConfig({
  entry: ['src/index.ts'],
  logLevel: 'silent',  // No output for automation
})

Fail on Warnings

The failOnWarn option controls whether warnings cause the build to exit with a non-zero code. Defaults to 'ci-only' — warnings fail the build in CI but not locally.

export default defineConfig({
  failOnWarn: 'ci-only', // Default: fail on warnings only in CI
  // failOnWarn: true,   // Always fail on warnings
  // failOnWarn: false,  // Never fail on warnings
})

See CI Environment for more about CI-aware options.
