When handling URLs in web applications, consistently normalize path formats to prevent routing and service communication issues. This is especially important when working with services like Istio that expect specific URL formats (e.g., trailing slashes).
When handling URLs in web applications, consistently normalize path formats to prevent routing and service communication issues. This is especially important when working with services like Istio that expect specific URL formats (e.g., trailing slashes).
Key implementation practices:
Example:
// Ensure trailing slash for service URLs that require it (e.g., Istio)
function normalizeServiceUrl(url: string): string {
return url?.endsWith('/') ? url : url + '/';
}
// When comparing URLs, normalize paths first
function equalUrlPaths(firstUrl: string, secondUrl: string): boolean {
// Handle sometimes missing '/' from URLs for consistent comparison
const normalizedFirst = firstUrl?.endsWith('/') ? firstUrl : firstUrl + '/';
const normalizedSecond = secondUrl?.endsWith('/') ? secondUrl : secondUrl + '/';
return normalizedFirst === normalizedSecond;
}
