Scrapy Settings Log

An extension that allows a user to display all or some of their scrapy spider settings at runtime. It will add a logline with some or all settings for your spider in JSON compatible format.

Install

pip install scrapy-settings-log

Quick-Start

Add the following to your settings:

EXTENSIONS = {
    'scrapy_settings_log.SpiderSettingsLogging': 999,
}

SETTINGS_LOGGING_ENABLED = True

When you run your spider you will see a log like below when spider is closing:

[scrapy_settings_log] INFO: {"SETTINGS_LOGGING_ENABLED": true, ...}

Additional Options

• SETTINGS_LOGGING_REGEX - Add a regular expression to only show some settings - for example SETTINGS_LOGGING_REGEX = "SPIDERMON" will show settings with SPIDERMON in their name.
• SETTINGS_LOGGING_INDENT - Add indentation to make log more human-readable.
• MASKED_SENSITIVE_SETTINGS_ENABLED - Default is True - if settings logging is enabled it will mask the value of settings that may be sensitive (password, apikey). For example AWS_SECRET_ACCESS_KEY will have their value shown as **********

Advanced

Subclass and override the output_settings method if you want the settings to be reported in another way.

from scrapy_settings_log import SpiderSettingsLogging

class CustomSettingsLogger(SpiderSettingsLogging):

    def  output_settings(self, settings: dict, spider: scrapy.Spider):
        # custom code here
