gopkg.in/chi.v3 (go): Package chi is a small, idiomatic and composable router for building HTTP services.  chi requires Go 1.7 or newer.  Example:  See github.com/go-chi/chi/_examples/ for more in-depth examples.  URL patterns allow for easy matching of path components in HTTP requests. The matching components can then be accessed using chi.URLParam(). All patterns must begin with a slash.  A simple named placeholder {name} matches any sequence of characters up to the next / or the end of the URL. Trailing slashes on paths must be handled explicitly.  A placeholder with a name followed by a colon allows a regular expression match, for example {number:\\d+}. The regular expression syntax is Go's normal regexp RE2 syntax, except that regular expressions including { or } are not supported, and / will never be matched. An anonymous regexp pattern is allowed, using an empty string before the colon in the placeholder, such as {:\\d+}  The special placeholder of asterisk matches the rest of the requested URL. Any trailing characters in the pattern are ignored. This is the only placeholder which will match / characters.  Examples:
