Handling different baseUrl when using firebase functions

[larssn]

Think I have the same problem. validate does absolutely nothing. I'm thinking it doesn't match the path.

@manwithsteelnerves Did you find a solution?

[manwithsteelnerves]

@larssn Are you using cloud functions? If so, you can try this hack.

import  { init, validate as internalValidate }  from    'openapi-validator-middleware';
init(path-to-schema, options);

export const validator = {
    validate  : () => (req: any, res: any, next: Function) => {
        req.baseUrl = req.baseUrl.replace(req.baseUrlPrefix , ""); //This is the patch

        console.time("Validate Request");
        internalValidate(req, res, next);
        console.timeEnd("Validate Request");

    }
}

We call validator.validate from our routes as a middleware call.

Thanks for the quick response!

We are indeed using cloud functions. However our Request object does not have a baseUrlPrefix, and the baseUrl is an empty string. Googling baseUrlPrefix doesn't yield much, is it a custom field you've made?

[larssn]

Figured it out, we had to do:

   validate  : () => (req: any, res: any, next: Function) => {
        req.baseUrl = '/v1';

        console.time("Validate Request");
        internalValidate(req, res, next);
        console.timeEnd("Validate Request");
    }

Thanks for the hint. Saved us some time!

I forgot to add how we have the baseUrlPrefix

router.use("/", async (req : express.Request, res : express.Response, next : express.NextFunction) => {
    req.locals = { context : {}};
    req.baseUrlPrefix = req.baseUrl; //Save this
    next();
});

We saved it in at very first router to avoid hardcoding :)
Sorry for not mentioning it!

@larssn @manwithsteelnerves glad to see you've managed.

Adding a baseUrlPrefix sounds like a legitimate feature and we'll consider adding that.

[manwithsteelnerves]

Great!
Just a small change.
Would be good if its req.locals.baseUrlPrefix
