Performance Issue at loading time

[manwithsteelnerves]

There is a significant delay(3-4secs) when loading the schema.
Is there any chance to cache the ajv instance so that addKeywords will be called once? AddKeywords seems to happen for every rest end point.

Please suggest.

Would you be able to also paste your code example of how you are using https://github.com/PayU/api-schema-builder could go a long way.

We are using as a dependency with in openapi-validator-middleware.
To give a quick overview, openapi-validator takes the schema path and internally uses this module for processing the schema.

I tried caching ajv instances for a quick test as and the performance got increased by 2x!!!
But i'm not sure if its fine to cache the below instances. Please correct me.

if(!ajv) {
        ajvOptions = Object.assign({}, defaultAjvOptions, options.ajvConfigParams);
        ajv = new Ajv(ajvOptions);
    
        ajvUtils.addCustomKeyword(ajv, options.formats, options.keywords);    
    }
