Like JSON.stringify, but doesn't blow up on circular refs.
npm install json-stringify-unsafeLike JSON.stringify, but doesn't throw on circular references.
Takes the same arguments as JSON.stringify.
``javascript`
var stringify = require('json-stringify-safe');
var circularObj = {};
circularObj.circularRef = circularObj;
circularObj.list = [ circularObj, circularObj ];
console.log(stringify(circularObj, null, 2));
Output:
`json`
{
"circularRef": "[Circular]",
"list": [
"[Circular]",
"[Circular]"
]
}
`
stringify(obj, serializer, indent, decycler)
The first three arguments are the same as to JSON.stringify. The last
is an argument that's only used when the object has been seen already.
The default decycler function returns the string '[Circular]'.function(k,v){}
If, for example, you pass in (return nothing) then itfunction(k,v){ return {foo: 'bar'}}
will prune cycles. If you pass in ,{"foo":"bar"}
then cyclical objects will always be represented as in
the result.
`
stringify.getSerialize(serializer, decycler)
Returns a serializer that can be used elsewhere. This is the actual
function that's passed to JSON.stringify.
Note that the function returned from getSerialize` is stateful for now, so
do not use it more than once.
