Is there any way to reuse compiled schema

[nomi-ramzan]

Hi
I am using AJV(latest) with express. here is current code

app.get('test', function (req, res, next) {
    var validate = ajv.compile(schema);
    if( !validate(req.body) ) return sendError(validate.errors)
    next();
})

Is there any way to do this. Like just compile it once and use clone/copy of it on each call.

var validate = ajv.compile(schema);

app.get('test', function (req, res, next) {
    if( !validate(req.body) ) return sendError(validate.errors)
    next();
})

I also tried clone, cloneDeep of lodash. But now working.
Thank you.

You should use your second code sample - that's exactly how it should be.

I tried this code. It will overwrite codes in case of multi calls at the same time. Let suppose two calls came and before sending errors of first call second call will overwrite errors then first call will send errors of second call instead of first call ( which i have lost now).

Can you please help me how can I clone deeply validate object ?

That's not correct. Validation is synchronous, JavaScript is single threaded. It could have only happened if you use the errors in the next execution block (in callback, nextTick, setTimeout etc.). Please see FAQ and #242 (comment)

So you don't need to clone, you just need to use your second sample, it doesn't have the problem you describe.
