Get real image path from json response

Question

I have a local express server that serves a json file. I also have many image files inside a local folder. The image paths are parts of the json object which I want to show in my DOM. However I get string representation of these image paths as part of response which I can't use. What is the best way to server local images to the frontend from a local server.

A picture of the issue :

My server side config:

 app.use(express.static(path.join(__dirname, 'public'))) app.use(express.static(path.join(__dirname, 'server/img'))) 

My JSON file

 { "Images": [{ "title": "First Block", "images": ["server/img/bijay.jpg", "server/img/dance.png", "server/img/ocean.jpg"] }, {obj2}, {obj3}, {obj4}] } 

My client-side code to print image

 <ul> <li ng-repeat="obj in objArray"><img ng-src="{{obj.images[0]}}"></li> </ul> // just testing first image 

My folder structure:

Images are inside the img folder. not shown here to save space

Answer 1

Finally after a lot of rethinking, I found the solution.

I had defined the 'static' folder in the server as 'server/img'. However, inside the json object, I was assigning the absolute path for the image files again. All I needed to do was ' server/image/ imgFileName.jpg' to resolve the conflict :))

Based on the comments of @Tolsee:

Place the images in a 'public' folder. (/public/img/dance.png) Then in your express app add the following line:

let app = express();
app.use(express.static(path.join(__dirname, 'public')));

The images will be available with the following url:

localhost:port/img/dance.png

You could just serve /server/img and then just use the following:

let app = express();
app.use(express.static('/server/img'));

localhost:port/dance.png

Some configuration might be needed depending on your project structure.
