Upload images in Angular and Node.js using Multer

[@FunOfHeuristic]

To access the uploaded files in server we need a static serving from node.js, for that just write "app.use(express.static('upload'))" ( upload is your folder name where you are storing your files/images), now we can access the images/files thought localhost://. 08:39 For multiple files, upload

[@patrickniyogitare]

if "app.use(express.static('upload'))" is not working and you are still getting 404 error code please try this "app.use('/upload', express.static('upload'));" it is all about giving public access to your uploads in upload directory.

Yes, you can either use the same image you have uploaded to show in the UI once you get the response from server that file is uploaded, or you can create a small thumbnail in the server and just send the url back in response

Sir, Your video is awesome but I have a query regarding it, how I send some extra data with file. Like I have created a reactive form where multiple fields like name of the user and other data. So how can I send the these data along with file.. Please suggest.....

[@FunOfHeuristic]

If you check in app.component.ts we are calling the BE with formdata, so you can append your fields and make a call to BE, and in BE you can access with the same key you have provided in the formdata

[@FunOfHeuristic]

You can append different parameters in the form data.

[@roccodenicolo3921]

@@FunOfHeuristic I append an object ( like product = { name: ' Hammer' } ) with FormData.append('product', product); but then I'm not able to retrieve the object in Express. for example if in express i print 'req.body' it returns [Object: null prototype] { product: '[object Object]' } how can I access to the field 'name' of product ?

[@FunOfHeuristic]

If you are sending an object with the formdata along side with the file then stringify the object and then append with key and in express fetch with the same key.

[@FunOfHeuristic]

Multer is used in node.js, so you can use a blob storage and can give access to the storage from your node app.

Hello , how can we save the images to mongodb and retrieve them back to angular for download option

[@FunOfHeuristic]

If your total files size per field in a document is greater then equal to 16MB then use GridFS if it's less then that then you can directly store using BinData / BufferData for the images. And to download you can send the buffer data from node to client and download the image in client.

[@FunOfHeuristic]

Hey, the easiest way is to create a JWT token and save it in the user database. You can send it via email with URL parameters. When the user clicks the link, you can extract the token from the URL and verify it with your database to ensure it's valid for that user. You can also set an expiration date and time while creating a JWT token.

If you check in the video I am sending the file in a form data and that is a kind of key-value pair, so you can give another name as key and put your field in the value and you can send multiples fields like that.

Basicly like this? const formData = new FormData(); formData.append('title', this.articleForm.get('title').value); formData.append('subtitle', this.articleForm.get('subtitle').value); formData.append('content', this.articleForm.get('content').value); formData.append('articleImage', this.articleImage); EDIT: Ok it works!
