Embed JSON readably in a URL

Ah, with more persistent googling, it looks like this is it: https://github.com/sage/jsurl

npm install jsurl

JSON:{"name":"John Doe","age":42,"children":["Mary","Bill"]}

JSURL:~(name~'John*20Doe~age~42~children~(~'Mary~'Bill))

JSON + URL encoding:%7B%22name%22%3A%22John%20Doe%22%2C%22age%22%3A42%2C%22children%22%3A%5B%22Mary%22%2C%22Bill%

In my case, that's:

console.log(jsurl.stringify({"version":"0.0.04","initSources":["init/nm.json",{"catalog":[{"name":"Thing 1","items":[{"name":"Fnerp","items":[{"name":"Background","nowViewingIndex":0,"isEnabled":true,"isShown":true,"isLegendVisible":true,"opacity":0.6}]}]}],"catalogOnlyUpdatesExistingItems":true},{"initialCamera":{"west":149.8687452406318,"south":-27.849159445374482,"east":154.32276951323334,"north":-24.936526601352618,"position":{"x":-5351310.197047934,"y":2833880.2585505643,"z":-2987073.4882188127},"direction":{"x":0.7925475007291486,"y":-0.4197074423977381,"z":0.44239588818605585},"up":{"x":-0.3909589511624161,"y":0.20703917597862256,"z":0.8968198693807059}},"homeCamera":{"west":105.00000000000001,"south":-45,"east":155,"north":-5}}]}));~(version~'0.0.04~initSources~(~'init*2fnm.json~(catalog~(~(name~'Thing*201~items~(~(name~'Fnerp~items~(~(name~'Background~nowViewingIndex~0~isEnabled~true~isShown~true~isLegendVisible~true~opacity~0.6))))))~catalogOnlyUpdatesExistingItems~true)~(initialCamera~(west~149.8687452406318~south~-27.849159445374482~east~154.32276951323334~north~-24.936526601352618~position~(x~-5351310.197047934~y~2833880.2585505643~z~-2987073.4882188127)~direction~(x~0.7925475007291486~y~-0.4197074423977381~z~0.44239588818605585)~up~(x~-0.3909589511624161~y~0.20703917597862256~z~0.8968198693807059))~homeCamera~(west~105.00000000000001~south~-45~east~155~north~-5))))
