Returning images as mock

For some use cases, we need to able to return image responses as mocks. Like GET.json or GET.xml, GET.jpeg should be returned for an image request. There are some tricky parts for this:

• For response type, we have auto type that is checking request content-type header and falls-back to json. But for images we should check mock files for this path in any case for image mock files.
• Respect to wildcard support(#25), checking all possible mock files will be a bit more complex.
• We should able to extend this approach for other type of responses. (Video, yaml etc.)

So idea is:

• If request is GET /path with accept type application/json we should only check path/GET.json

Request method	Request path	Accept type	Mock file to be checked
GET	/path	application/json	path/GET.json
GET	/path	application/xml	path/GET.xml
GET	/path	image/*	path/GET.(jpeg|gif|png…)
GET	/path	*/*	path/GET.(json|xml|jpeg|gif|png…)

* Custom middlewares should have priority in any case ** If there is no prefered accept type and if there is a json mock file, it should be prioritised

Yes. I have find a solution (nearly your response). I have using GET.js rather than GET.jpg and sends a image through GET.js

Here is screenshot of my files (a little)

And its my GET.js file module.exports = function(req, res){ res.sendFile('img.jpg', {root: __dirname}); };

When i starts a dev-server and then implement the endpoint. Its going works… Thanks 👍 👍 👍

I just added 2 new helper functions(type and file) and published with v1.8.0. So Your custom response can be that much simple for this use case:

const { type, file } = require('connect-api-mocker/helpers');
 
// Assuming a file named GET.png exists next to this file
const filePath = path.join(__dirname, './img.jpg');
 
module.exports = [type('image/jpeg'), file(filePath)];

But still, I want to implement the idea that I mentioned in first comment. I think it would be more elegant solution.
