Relaxed JSON

Are you frustrated that you cannot add comments into your configuration JSON Relaxed JSON is a simple solution. Small JavaScript library with only one exposed function RJSON.transform(text : string) : string (and few convenient helpers).

Relaxed JSON (modified BSD license) is a strict superset of JSON, relaxing strictness of valilla JSON. Valid, vanilla JSON will not be changed by RJSON.transform. But there are few additional features helping writing JSON by hand.

• Comments are stripped : // foo and /* bar */ →      . Comments are converted into whitespace, so your formatting is preserved.
• Trailing comma is allowed : [1, 2, 3, ] → [1, 2, 3]. Works also in objects { "foo": "bar", } → { "foo": "bar" }.
• Identifiers are transformed into strings : { foo: bar } → { "foo": "bar" }.
• Single quoted strings are allowed : 'say "Hello"' → "say \"Hello\"".
• More different characters is supported in identifiers: foo-bar → "foo-bar".
