I think that would be great. The problem I'm trying to solve is that I have the validator chains already built and in a library I share between projects and I want to reuse them as much as possible, now I want to use the same chains to validate rows from a csv upload. And I would like every row in the CSV to be validated with the same chains I use for the post request.

do we want to make a shift allowing validations to run on express requests and on plain json objects too?

Yeah, I think this can be done.

I'm marking this issue as an enhancement then, but please note it might take a few weeks/months before I'm able to get around to working on it @syco

I may do that this week. It shouldn't take me more than a couple hours to get it working.

Hey,
In theory you can, it's how most of the tests are written, but all of express-validator assumes a request-like structure.

express-validator/src/express-validator.spec.ts

Lines 158 to 163 in 28a8d5f

 it('can be used on custom chains', async () => { 

 const req = { query: { foo: 1 } }; 

 const { check, matchedData } = createInstance(); 

 await check('foo').isAllowedDomain().run(req); 

 const data = matchedData(req);

...but this might be weird when you're not near the HTTP layer of your application (e.g. "why does this object have a body/cookie/query/header/param property")

You might like using pure validator.js instead: https://github.com/validatorjs/validator.js/
You'd need to validate each property you care about. And at of the time of writing, it'll throw if the input is not a string, which might or might not be annoying for you.

Then there are plenty other libraries for object validation out there.
