x-express-openapi-additional-middleware when not using JS APIDoc?

Is it possible to inject middleware that fires on all routes without using a JavaScript APIDoc?

I want to validate & load data based on the route provided (after req.params are initialized but before any services) while keeping the APIDoc in JSON or YAML for documentation generation.

As a work-around I’m keeping the API Doc separate then adding x-express-openapi-additional-middleware:

const fs = require('fs');
const path = require('path');
const validate = require('../middleware/validate');

let apiDoc = JSON.parse(fs.readFileSync(path.resolve(__dirname, './api-doc.json'), 'utf8'));
apiDoc['x-express-openapi-additional-middleware'] = [validate];

module.exports = apiDoc;

Is there an initialize setting I’m missing?

e.g.

    openapi.initialize({
        apiDoc: fs.readFileSync(path.resolve(__dirname, './api-doc.json'), 'utf8'),
        app: app,
        paths: path.resolve(__dirname, './routes'),
        middleware: {validate: validate}
    });

That sounds great -

Having to merge logic into JSON or YAML isn’t a deal-breaker. I’m very happy with how fully Swagger 2.0 is supported; thanks for all the hard work on this project!
