Direct answer

To use base64-url-encoder, start with a small representative input, encode a known input and verify round-trip behavior, and inspect the result before relying on it.

Key takeaways

  • Purpose: encode a known input and verify round-trip behavior.
  • Check: round-trip fidelity, encoding rules and Unicode handling.
  • Limitation: encoding does not encrypt or protect sensitive data.

Common mistakes

  • Assuming the output is correct because the operation completed. Instead, inspect round-trip fidelity, encoding rules and Unicode handling.
  • Using production or confidential material as the first test. Use a sample string containing a space, ampersand and non-ASCII character instead.
  • Ignoring compatibility: encoding does not encrypt or protect sensitive data.
