Continuous
Deep Code Review

AppMap finds critical code quality problems by analyzing
application runtime data, right in your code editor.

  1. # Returns true if the given token matches the digest

  2. def authenticated?(attribute, token) AppMap map icon

  3. if attribute == :reset

  4. token = YAML.load(Base64.urlsafe_decode64(token))

    squiggle
  5. end

  6. valid_token?(token)

  7. end
