Build a profanity filter API with GraphQL

Detecting and filtering profanity is essential for maintaining safe and age-appropriate communication spaces in various applications, such as social media apps and comment sections. A tutorial demonstrates how to create a GraphQL API using Python and Flask to detect and filter profanity, starting with a basic word-list approach and advancing to a more sophisticated solution using the better-profanity Python library. This library offers enhanced functionality, including custom word lists, detection of modified spellings, and multilingual capabilities. The guide provides detailed instructions on setting up the API, writing GraphQL schemas, and configuring the application server, culminating in a working API that can be tested via the GraphiQL interface. Additionally, the tutorial highlights common challenges in profanity detection, such as language subversions and false positives, while offering practical solutions to address these issues. The source code is available on GitHub, and tools like LogRocket are recommended for monitoring GraphQL requests in production to ensure reliability and efficient debugging.
