This value is very important, because we will send our file to a server under this key. We are providing an ‘ image’ value to it. The new one is more specific with additional configuration for a single image upload. We are exporting our upload object that we’ve created before and creating a new one from it. We need to expose this functionality to them. We are almost done, but users of our app still don’t have access to the image upload. Uploaded file with a current time nameĪfter all the setup, we are exporting the upload object in order to use it in other files. This way our filename will always be unique, but you can choose whatever name you want. In our case, we are making a timestamp of a current time and saving this file under this name. key: callback function to set the key property (under which key your file will be saved in your bucket). You can see this data on the image bellow.ĥ. Here, I am setting additional metadata for a fieldName. metada: callback function to set metadata of uploaded files.acl: access control for the file (‘public read’ means that anyone can view files), you can check all the available types here: amazon link.bucket: name of our bucket (in my case: “medium-test”).s3: instance of Amazon S3 we created before.We need to provide function to the multer object with the following properties. Now, we can set up a solution for a multer upload. Now, let’s see the second part of this implementation. We need to provide our secret keys and region from the URL bar I showed you before.Īfter AWS configuration, we can create an instance of our Amazon S3. įirst, we are importing all our installed packages. Best solution would be to use aws-profiles. Important note: Never expose your secret credentials directly into file! Never share your secret credentials! Consider to setup environment variables in your local environment or in case of deployed projects, variables in your cloud provider. Create your file-upload service with the following implementation (first part):.(You can find links at the end of this blog post). If you are interested in the whole project implementation, check my GitHub repository or watch the full tutorial. This tutorial is focused only on the file upload. I will not explain the basics of Node or Express here. Never share your keys with anyone! Temporary save these keys to some file or download the Key File, because we need keys in order to set up a file upload.Īll right.

Amazon offers an amazing free tier you can use for the 1st year. Signup for AWSįirst, let’s create an account on.

Multer-s3: multer extension for an easy file upload to Amazon S3 service. Multer: middleware for handling data files. What we need to install & a short description. You can find a link in the resources at the bottom of this article. I prepared a video tutorial on YouTube as well. This is the first part of a tutorial in which we will handle the server (Node.js) part of the code. do any upload stuff here with the JS-File-Object return Promise.By Filip Jerga How to set up simple image upload with Node and AWS S3 A step-by-step guide explaining how to upload an image or any file to Amazon S3 service. Resolves to the full URL of the uploaded image. This hook is called with the JS-File-Object as parameter and has to return a Promise which Installation: npm i plugin uses a hook which can be configured like shown below.
