velopack / velopack.fusion

Velopack client libraries for a variety of programming langauges

---

Velopack is an installation and auto-update framework for cross-platform applications. It's opinionated, extremely easy to use with zero config needed. With just one command you can be up and running with an installable application, and it's lightning fast for your users, too.

Features

• 😍 Zero config – Velopack takes your compiler output and generates an installer, updates, delta packages, and self-updating portable package in just one command.
• 🎯 Cross platform – Velopack supports building packages for Windows, OSX, and Linux, so you can use one solution for every target.
• 🚀 Automatic migrations - If you are coming from other popular frameworks (eg. Squirrel), Velopack can automatically migrate your application.
• ⚡️ Lightning fast – Velopack is written in Rust for native performance. Delta packages mean your user only downloads what's changed between versions.
• 📔 Language agnostic - With support for C#, C++, JS, Rust and more. Use a familiar API for updates no matter what language your project is.

Testimonials

I have now got my external facing application using velopack. I am very impressed. Seems to work fabulously well and be much faster both in the initial build and in the upgrading of the software on the end user's machine than Squirrel was. It's amazing and the best installer I've ever used in over 30 years of development. Thanks so much! You are doing some great work! - Stefan (Discord)

Just wanted to say a huge thank you. I've been using Clowd.Squirrel for a couple of years now since Squirrel.Windows wasn't working for me. Just popped into that repository today to look for some documentation and noticed the release of Velopack. How unexpected! It works fantastic and is so much faster, wow! Thank you again, the amount of work that went into both Clowd.Squirrel and Velopack is staggering. It's very appreciated. - Kizari (Discord)

I've used a lot of installer frameworks and Velopack is by far the best. Everything is like magic: you run the installer, and then the app is just open, ready to use. Updates apply and relaunch in ~2 seconds with no UAC prompts. The installer creation process is painless and integrates easily with code signing, and the command-line tool makes it simple to upload your updater files. You don't need to futz with separate installer scripts in some weird language; you can build all those hooks into your main app! The support is also phenominal; every concern I've had has been addressed. This is the future of desktop installers. - RandomEngy (Discord)

velopack.fusion's Issues

Fusion API feed rework

In order to fully support the CLI and expose some more fine grained control, we should modify the API

• new "get_feed()" function to return all available releases (both Rust & CLI)
• "download" cli function needs to take a release name, and download that specific release.
• new "get-packages-dir" function to return the path to the current app packages dir (CLI only)

With these changes, it will be possible for an application developer to list all available releases, then choose a specific release to download and apply, rather than being forced to rely on the default version selection behavior.

Support delta packages

At the moment, fusion only supports downloading full releases. The delta logic needs to be replicated here.

Support GitHub Releases

Since update source is now passed by string (From fusion to the cli) we should implement a GithubUpdateSource in rust and then add some regex matching to see if that should be used instead of HttpSource.

Improvements to C++ lib

Future improvements:

• Qt should have some special support, eg. AutoUpdate from the Qt sample built in
• Eventually, the Vfusion binary logic is going to get moved into Update.exe, which is already distributed with your app automatically, so you don't need to bring that binary yourself.
• Add CMake scripts and distribute it on vcpkg so it's easy for developers to install and update.

Compile the sample:

• Qt installed somewhere on your computer (use this: https://github.com/miurahr/aqtinstall)
• configure with cmake giving it instructions where Qt libs are
• build
• "install"
• vpk pack
• test

In a c++ cmake project, extending it with libraries is pretty much:

1. add library repo as submodule
2. Add 1-2 commands in parent cmake to embed/compile library statically or dynamically
3. #include <Library.h>
4. PROFIT!

With vcpkg it's the same except without the first step.

Tauri Support

Does Velopack support Tauri?

I'm hitting the NSIS 2GB limit and was wondering if Velopack could be a solution.

Latest build not available anymore

Hey, the build artifacts appear to have expired. I'm trying to build an integration just using the Fusion CLI so would be great to have access to the latest build without having to build it myself. Would probably be best to have the latest build as a Github Release.

Statically link VCRedist

VFusion.exe needs to statically link the runtime to be fully portable

Fusion should replace Update.exe when downloading packages

To maintain feature parity with the NuGet package, Update.exe should be auto-updated when downloading packages
