Warp

Warp lets you create self-contained single binary applications making it simpler and more ergonomic to deliver your application to your customers. A self-contained binary is specially convenient when the technology you use, such as .NET Core, Java and others, contain many dependencies that must be shipped alongside your application.

Warp is written in Rust and is supported on Linux, Windows and macOS.

Quickstart with .NET Core

Linux

Create a simple console application

dgiagio@X1:~/Devel$ mkdir myapp
dgiagio@X1:~/Devel$ cd myapp
dgiagio@X1:~/Devel/myapp$ dotnet new console
dgiagio@X1:~/Devel/myapp$ dotnet run
Hello World!
dgiagio@X1:~/Devel/myapp$

Publish the application with native installer for linux-x64 runtime

dgiagio@X1:~/Devel/myapp$ dotnet publish -c Release -r linux-x64

The application should be published to bin/Release/netcoreapp2.1/linux-x64/publish/

Download warp-packer

If you save warp-packer in a directory in your PATH, you only need to download it once.

dgiagio@X1:~/Devel/myapp$ curl -Lo warp-packer https://github.com/dgiagio/warp/releases/download/v0.1.0/linux-x64.warp-packer
dgiagio@X1:~/Devel/myapp$ chmod +x warp-packer

Create your self-contained application

dgiagio@X1:~/Devel/myapp$ ./warp-packer --arch linux-x64 --input_dir bin/Release/netcoreapp2.1/linux-x64/publish --exec myapp --output myapp
dgiagio@X1:~/Devel/myapp$ chmod +x myapp

Run your self-contained application

dgiagio@X1:~/Devel/myapp$ ./myapp
Hello World!
dgiagio@X1:~/Devel/myapp$

More information about your self-contained application

Hello World!
Diegos-iMac:myapp dgiagio$

Publish the application with native installer for osx-x64 runtime

Diegos-iMac:myapp dgiagio$ dotnet publish -c Release -r osx-x64

The application should be published to bin/Release/netcoreapp2.1/osx-x64/publish/

Diegos-iMac:myapp dgiagio$ chmod +x warp-packer

Create your self-contained application

Diegos-iMac:myapp dgiagio$ ./warp-packer --arch macos-x64 --input_dir bin/Release/netcoreapp2.1/osx-x64/publish --exec myapp --output myapp
Diegos-iMac:myapp dgiagio$ chmod +x myapp

Run your self-contained application

Diegos-iMac:myapp dgiagio$ ./myapp
Hello World!
Diegos-iMac:myapp dgiagio$

More information about your self-contained application

Diegos-iMac:myapp dgiagio$ file myapp
myapp: Mach-O 64-bit executable x86_64

Diegos-iMac:myapp dgiagio$ du -hs myapp
 27M    myapp

Windows

Create a simple console application

PS C:\Users\Diego\Devel> mkdir myapp
PS C:\Users\Diego\Devel> cd myapp
PS C:\Users\Diego\Devel\myapp> dotnet new console
PS C:\Users\Diego\Devel\myapp> dotnet run
Hello World!
PS C:\Users\Diego\Devel\myapp>

Publish the application with native installer for win10-x64 runtime

PS C:\Users\Diego\Devel\myapp> dotnet publish -c Release -r win10-x64

The application should be published to bin/Release/netcoreapp2.1/win10-x64/publish/

Download warp-packer

If you save warp-packer in a directory in your PATH, you only need to download it once.

PS C:\Users\Diego\Devel\myapp> [Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls" ; Invoke-WebRequest https://github.com/dgiagio/warp/releases/download/v0.1.0/windows-x64.warp-packer.exe -OutFile warp-packer.exe

Create your self-contained application

PS C:\Users\Diego\Devel\myapp> .\warp-packer --arch windows-x64 --input_dir bin/Release/netcoreapp2.1/win10-x64/publish --exec myapp.exe --output myapp.exe

Run your self-contained application

PS C:\Users\Diego\Devel\myapp> .\myapp.exe
Hello World!
PS C:\Users\Diego\Devel\myapp>

Quickstart with Java

How it works

Warp is a multi-platform tool written in Rust and is comprised of two programs: warp-runner and warp-packer.

The final self-contained single binary application consists of two parts: 1) runner and 2) the compressed target application executable and dependencies.

warp-runner is a stub application that knows how to find the compressed payload within its own binary, perform extraction to a local cache and execute the target application.

The extraction process only happens the first time the application is ran, or when the self-contained application binary is updated.

warp-packer is a CLI application that's used to create the self-contained application binary by downloading the matching warp-runner for the chosen platform, compressing the target application and its dependencies, and generating the final self-contained binary.

Performance

The performance characteristics of the generated self-contained application is roughly the same of original application, except for the first time it's ran as the target application and its dependencies have to be decompressed to a local cache.
