Redirects
Setting up HTTP redirects is simple with SVR.JS. You can add a 301 or 302 code (with scode property set to 301 or 302) entry to the nonStandardCodes property in config.json. The entry should specify the source URL for the redirect in the url or regular expression string for the redirect in regex property (for example "/\\/blog($|[#?\\/].*)/"), and the destination URL in the location property (for regular expressions, you can use for example "$1" for contents of first capturing group). Destination location can be relative to current site (for example /blogs) or a full URL (for example https://blog.example.com).
Please be cautious when setting up redirects to avoid redirect loops, as they can cause unintended behavior and potentially impact the performance of your server.
From SVR.JS 3.8.0 onwards, you can specify a hostname for which this redirect applies in host property. If you want to move your website to new address, you can add redirect to new website and specify host property to be host name of the old website (for example oldsite.example), location property to be a location of new website with "$1" appended (for example "https://newsite.example$1") and regex property to be "/(.*)/" (regular expression, which matches everything to capturing group).
URL rewriting
You can set up URL rewriting by adding entries to rewriteMap property in config.json file. See "config.json properties" section for URL rewrite rules syntax.
Log viewing
To make log viewing easier, SVR.JS 3.x and later included it's log viewer utility under logviewer.js. SVR.JS log viewer is interactive.
You can also manually view logs, and highlight them using SVR.JS log highlighter utility under loghighlight.js (SVR.JS 3.0.0 or newer). Usage: <some process> | node loghighlight.js [-h] [--help] [-?] [/h] [/?].
SVR.JS stores it's logs in log directory. Server logs look like this:
