The article uses the Express framework for easing the generation of a simple webserver. Although it’ll focus on a barebones Node.js application, the process can be applied to Node.js running in any environment - including on Heroku or in a serverless deployment. The rest of this article covers the process of building in direct-to-B2 uploading in a Node.js application. This means that the browser does the uploading directly to your B2 bucket without files having to go through your server. These factors are particularly relevant to apps deployed on Heroku or on a serverless architecture.Īs such, this article covers the concept of direct uploading to B2. these can be largely outweighed by the fact that the server must consume more resources (both CPU and RAM), which means that the approach becomes less scalable.įurthermore, not all application deployments allow for local filesystem storage, and processing large files server-side may cause requests to timeout. Whilst this approach may offer some advantages - such as the ability to run on-the-fly processing, image resizing, watermarking, etc. This may be by writing the contents to a local filesystem, or passing on the object to some other storage mechanism.

In these cases, the server-side code must receive the file, process it, and then proceed to persist it somehow. Some apps accept file uploads through a standard POST request as part of a form submission. In particular, Backblaze’s pricing model makes B2 stand out amongst its competitors. Object storage often considered a good solution for storing user-uploaded content as it is cost-effective, scalable, robust, and can be used to store a wide range of file types. This is important for deploying to a PaaS such as Heroku due to the ephemeral file system.ī2 is an S3-compatible object storage service, which means that the approach described in this article can largely be applied to other S3-compatible services too, such as Amazon S3, Linode Object Storage, and DigitalOcean Spaces. This article describes how to use Node.js file uploads to power direct upload functionality to a Backblaze B2 bucket.
