# json-stringify-safe
|
|
|
|
Like JSON.stringify, but doesn't throw on circular references.
|
|
|
|
## Usage
|
|
|
|
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]"
|
|
]
|
|
}
|
|
```
|
|
|
|
## Details
|
|
|
|
```
|
|
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]'`.
|
|
If, for example, you pass in `function(k,v){}` (return nothing) then it
|
|
will prune cycles. If you pass in `function(k,v){ return {foo: 'bar'}}`,
|
|
then cyclical objects will always be represented as `{"foo":"bar"}` 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.
