passing route specific arguments to body parser plugin

[amitguptagwl]

I was trying to write a body parser to support multiple content types. To parse nimn to json, I need to pass simplified object structure to the parser which is accepted by particular route.

var nimnInstance = new nimn();
nimnInstance.addSchema(schema);
//some code here
var nimndata = nimnInstance.encode(jObj);
var jObj2 = nimnInstance.decode(nimndata);

I do not understand what is the problem, what do you want to achieve, and how we can help. Can you please articulate further?

Sorry for the confusing language. I've got the answer while exploring other examples. Many thanks for your quick response.

Reopening and updating the question

I'm trying to write a body parser which converts nimn data format to js object. For this, I need to know the object structure of target json which can be different for each route. So how can I pass options with every route so that body parser can parse request payload to js obj accordingly?

const opts = {
  schema: {}
};
fastify.get('/', opts, (request, reply) => {
  //write some code here
})

As per above snippets, I want to access opts in body parser plugin.

You should really post this issue in the Fastify repo. This is just a little utility to help writing plugins.

[amitguptagwl]

sure thanks. I'll do

[amitguptagwl]

should I ask in fastify or fastify/help?

I would go for the main repo, this functionality is not there. We only support schema-based behavior through https://github.com/fastify/fastify/blob/master/docs/Validation-and-Serialization.md#schema-compiler, but it's JSON-only.

[amitguptagwl]

Exactly. I believe both functionalities should be implemented in the same way, so it can facilitate 3rd party plugins too.
