VisualizaçõesGet real image path from json response
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 imageMy folder structure:
Images are inside the img folder. not shown here to save space

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.
