Questions about a web client library, or how to integrate Storj as an app developer?

[Alexey]

Hello @Wes,
Welcome to the forum!

Currently you cannot use only client (browser) libraries to use a native protocol due to browser’s limitations:

JS library for the browser

Hey friends! We currently do not have client-side in-browser Javascript (or WASM) bindings on the 2020 roadmap, but we have made some exciting and relatively unexpected progress just this week that make it much more feasible. At a high level, there are a couple of challenges we need to overcome for this to work: We need the code running inside the browser. This is relatively straightforward these days to be honest - even though the Uplink library is large, Go natively can target WASM modules…

However we have some web assembly implementations

New Project using Storj

Hi @zesantos! We have a couple of layers of things - An API Key is the credential the Satellite needs to authorize a request. This can be restricted in a variety of ways. An Access Grant is a client-side only serialized envelope that contains an API Key and encryption keys for what the API Key allows for. The access grant actually keeps what’s called an “encryption store” which is a serialized database of mappings of path prefixes to derived encryption key roots. This allows you to restrict a…

But generally server-less is possible only for S3 protocol at the moment:

Is there a tool to upload direct to Storj from my browser client?

AFAIK satellite UI uses S3 protocol, satellite backends are metadata only services. Here is the aws sdk which is used by our UI (but any other S3 compatible JS library should work as well): “@aws-sdk/signature-v4”: “3.78.0”, It’s initialized and used in this file. The only Storj specific part is the secret handling. As a reminder: native Storj upload (which is not supported from the browser) requires an access grant (includes the API key + the encryption secret). This can be registere…

So, for the native protocol you need to have a backend and there you may use any of bindings: SDKs - Storj Docs
Even if some are outdated they still works.
Most customers uses our Storj-hosted S3-Gateway and/or presigned URLs, especially for light mobile apps to make their implementation easier, but they of course loose the CDN-like behavior in this case.
However we have implementations of a native protocol in the Mobile app for Android: Storj Mobile App - what would you like to see?
I would also add:

• Photos+, an app like Google photos, is now offering a free upgrade
