Name	Config Option	Description	default
baseUrl	with_base_url("https://config.ff.harness.io/api/1.0")	the URL used to fetch feature flag evaluations. You should change this when using the Feature Flag proxy to http://localhost:7000	https://config.ff.harness.io/api/1.0
eventsUrl	with_events_url("https://events.ff.harness.io/api/1.0"),	the URL used to post metrics data to the feature flag service. You should change this when using the Feature Flag proxy to http://localhost:7000	https://events.ff.harness.io/api/1.0
pollInterval	Config(pull_interval=60)	when running in stream mode, the interval in seconds that we poll for changes.	60
enableStream	with_stream_enabled(True),	Enable streaming mode.	true
enableAnalytics	with_analytics_enabled(True)	Enable analytics. Metrics data is posted every 60s	true
pollInterval	with_poll_interval(120)	When running in stream mode, the interval in seconds that we poll for changes.	60
maxAuthRetries	with_max_auth_retries(10)	The number of retry attempts to make if client authentication fails on a retryable HTTP error	10

Anonymous Target

If you do not want a Target to be sent to Harness servers, you can use the anonymous attribute.

    target = Target(identifier='my_identifier', name='my_name', anonymous=True)

Logging Configuration

The SDK provides a logger that wraps the standard python logging package. You can import and use it with:

from featureflags.util import log
log.info("Hello, World!")

If you want to change the default log level, you can use the standard logging levels

from featureflags.util import log
import logging

log.setLevel(logging.WARN)

Setting up your Feature Flags

Feature Flags Getting Started

Other Variation Types

String Variation

client.string_variation('identifier_of_your_string_flag', target, "default string")

Example

Number Variation

client.number_variation('identifier_of_your_number_flag', target, -1)

Example

JSON Variation

client.json_variation('identifier_of_your_json_flag', target, {})

Example

Cleanup

Call the close function on the client

client.close()

Example

Change default URL

When using your Feature Flag SDKs with a Harness Relay Proxy you need to change the default URL.

To do this you import the url helper functions

from featureflags.config import with_base_url
from featureflags.config import with_events_url

Then pass them with the new URLs when creating your client.

    client = CfClient(api_key,
                      with_base_url("https://config.feature-flags.uat.harness.io/api/1.0"),
                      with_events_url("https://event.feature-flags.uat.harness.io/api/1.0"))
