Logging

The CLI uses pino for structured logging with pretty-printed output by default.

Output Modes

Pretty Print (Default)

Human-readable output with colors, suitable for interactive terminal use:

[18:31:58] INFO: Deploying cartridges...
[18:31:59] INFO: Upload complete

JSON Lines (--jsonl)

Machine-readable output for scripting, CI/CD pipelines, and log aggregation:

b2c code deploy --jsonl

{"level":"info","time":1764113529411,"command":"code deploy","msg":"Deploying cartridges..."}
{"level":"info","time":1764113529412,"command":"code deploy","msg":"Upload complete"}

Log Levels

Control verbosity with --log-level or -D for debug:

Level	Description
trace	Maximum verbosity
debug	Detailed operational info
info	Normal messages (default)
warn	Warnings
error	Errors only
silent	No output

b2c code deploy --log-level debug
b2c code deploy -D  # shorthand for --log-level debug

In debug/trace mode, context objects are displayed:

[18:31:58] INFO: Upload complete
    command: "code deploy"
    file: "cartridge.zip"
    bytes: 45678
    duration: 1234

Flags

Flag	Environment Variable	Description
--log-level	SFCC_LOG_LEVEL	Set log verbosity
-D, --debug	SFCC_DEBUG	Enable debug logging
--jsonl, --json-logs	SFCC_JSON_LOGS	Output log messages as JSON lines
--json		Output command result as JSON

Environment Variables

Variable	Description
SFCC_LOG_LEVEL	Log level (trace, debug, info, warn, error, silent)
SFCC_DEBUG	Enable debug logging
SFCC_LOG_TO_STDOUT	Send logs to stdout instead of stderr
SFCC_REDACT_SECRETS	Set to false to disable secret redaction
NO_COLOR	Industry standard to disable colors
DEBUG	Set to oclif* for CLI framework debug logs

CLI Framework Debugging

For low-level debugging of the CLI parser and command loading, use the oclif debug flag:

DEBUG=oclif* b2c code deploy

This outputs internal oclif framework logs, useful for troubleshooting command resolution, plugin loading, and argument parsing issues.

Output Streams

By default, logs go to stderr so that command output (data, IDs, etc.) can be piped cleanly:

# Logs go to stderr, JSON output goes to stdout
b2c sites list --json 2>/dev/null | jq '.sites[0].id'

To send logs to stdout instead:

SFCC_LOG_TO_STDOUT=1 b2c code deploy

Secret Redaction

Sensitive fields are automatically redacted from log output:

• password, secret, token
• client_secret, access_token, refresh_token
• api_key, authorization

[18:31:58] INFO: Authenticating
    client_id: "my-client"
    client_secret: "[REDACTED]"

To disable redaction (for debugging):

SFCC_REDACT_SECRETS=false b2c code deploy --debug

CI/CD Usage

For CI/CD pipelines, use JSON lines log output and disable colors:

NO_COLOR=1 b2c code deploy --jsonl 2>&1 | tee deploy.log

Or explicitly set the log level:

SFCC_LOG_LEVEL=info b2c code deploy --jsonl
