-|  [assertNever(x)](./kibana-plugin-core-public.assertnever.md) | Can be used in switch statements to ensure we perform exhaustive checks, see https://www.typescriptlang.org/docs/handbook/advanced-types.html\#exhaustiveness-checking |

-|  [isRelativeUrl(candidatePath)](./kibana-plugin-core-public.isrelativeurl.md) | Determine if a url is relative. Any url including a protocol, hostname, or port is not considered relative. This means that absolute \*paths\* are considered to be relative \*urls\* |
-|  [modifyUrl(url, urlModifier)](./kibana-plugin-core-public.modifyurl.md) | Takes a URL and a function that takes the meaningful parts of the URL as a key-value object, modifies some or all of the parts, and returns the modified parts formatted again as a url.<!-- -->Url Parts sent: - protocol - slashes (does the url have the //) - auth - hostname (just the name of the host, no port or auth information) - port - pathname (the path after the hostname, no query or hash, starts with a slash if there was a path) - query (always an object, even when no query on original url) - hash<!-- -->Why? - The default url library in node produces several conflicting properties on the "parsed" output. Modifying any of these might lead to the modifications being ignored (depending on which property was modified) - It's not always clear whether to use path/pathname, host/hostname, so this tries to add helpful constraints |
