JSON.stringify is very slow for large objects
I have a very big object in javascript (about 10MB).
And when I stringify it, it takes a long time, so I send it to backend and parse it to an object( actually nested objects with arrays), and that takes long time too but it's not our problem in this question.
The problem:
How can I make JSON.stringify faster, any ideas or alternatives, I need a javaScript solution, libraries I can use or ideas here.
What I've tried
I googled a lot and looks there is no better performance than JSON.stringify or my googling skills got rusty!
Result
I accept any suggestion that may solve me the long saving (sending to backend) in the request (I know its big request).
Code Sample of problem (details about problem)
Request URL:http://localhost:8081/systemName/controllerA/update.html;jsessionid=FB3848B6C0F4AD9873EA12DBE61E6008
Request Method:POST
Status Code:200 OK
Am sending a POST to backend and then in JAVA
request.getParameter("BigPostParameter")
and I read it to convert to object using
public boolean fromJSON(String string) {
if (string != null && !string.isEmpty()) {
ObjectMapper json = new ObjectMapper();
DateFormat dateFormat = new SimpleDateFormat(YYYY_MM_DD_T_HH_MM_SS_SSS_Z);
dateFormat.setTimeZone(TimeZone.getDefault());
json.setDateFormat(dateFormat);
json.configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);
WebObject object;
// Logger.getLogger("JSON Tracker").log(Level.SEVERE, "Start");
try {
object = json.readValue(string, this.getClass());
} catch (IOException ex) {
Logger.getLogger(JSON_ERROR).log(Level.SEVERE, "JSON Error: {0}", ex.getMessage());
return false;
}
// Logger.getLogger("JSON Tracker").log(Level.SEVERE, "END");
return this.setThis(object);
}
return false;
}
Like This
BigObject someObj = new BigObject();
someObj.fromJSON(request.getParameter("BigPostParameter"))
P.S : FYI this line object = json.readValue(string, this.getClass());
is also very very very slow.
Again to summarize
Problem in posting time (stringify) JavaScript bottle nick.
Another problem parsing that stringified into an object (using jackson), and mainly I have svg tags content in that stringified object as a style column, and other columns are strings, int mainly

As commenters said - there is no way to make parsing faster.
If the concern is that the app is blocked while it's stringifying/parsing then try to split data into separate objects, stringily them and assemble back into one object before saving on the server.
If loading time of the app is not a problem you could try to ad-hoc incremental change on top of the existing app.
- ... App loading
- Load map data
- Make full copy of the data
- ... End loading
- ... App working without changes
- ... When saving changes
- diff copy with changed data to get JSON diff
- send changes (much smaller then full data)
- ... On server
- apply JSON diff changes on the server to the full data stored on server
- save changed data
I used json-diff https://github.com/andreyvit/json-diff to calc changes, and there are few analogs.
