NuGet Gallery — Where packages are found

This project powers nuget.org, the home for .NET's open-source ecosystem. For information about NuGet, visit the Home repository.

This project has adopted the Microsoft Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact opencode@microsoft.com with any additional questions or comments.

Getting started

First install prerequisites:

  1. Visual Studio 2022 - Install the following Workloads and individual components:
    • ASP.NET and web development
    • Azure development
    • Just web UI functional tests: "Web performance and load testing tools" individual component

Visual Studio 2019 may work but Visual Studio 2022 is recommended.

The "Azure development" workload installs SQL Server Express LocalDB which is the database configured for local development.

Run the gallery website locally

This repository contains both the gallery web app (what runs www.nuget.org) as well as background jobs and shared libraries.

Let's focus on running the gallery web app locally, first.

  1. Clone the repository with git clone https://github.com/NuGet/NuGetGallery.git
  2. Navigate to .\NuGetGallery
  3. Build with .\build.ps1
  4. Create the database and enable HTTPS with .\tools\Setup-DevEnvironment.ps1
  5. Open .\NuGetGallery.sln using Visual Studio
  6. Ensure the NuGetGallery project is the StartUp Project and press F5 to run the site

Refer to our documentation for information on how to develop the frontend, use AAD, and more.

Shared libraries

There are a set of shared libraries used across the NuGet server repositories, including:

  • NuGet.Services.Configuration
  • NuGet.Services.KeyVault
  • NuGet.Services.Logging
  • NuGet.Services.Owin
  • NuGet.Services.Cursor
  • NuGet.Services.Storage

To edit them, follow these steps:

  1. Build with .\build.ps1
  2. Open .\NuGet.Server.Common.sln using Visual Studio
  3. Create the validation database:
    • Open Package Manager Console, set NuGet.Services.Validation as default project, then run Update-Database.

Note that many of these shared projects are also referenced by the other solution (e.g. in NuGetGallery.sln) files in the root of the repository, to simplify modification.

Background jobs

This repository also contains nuget.org's implementation of the NuGet V3 API as well as many other back-end jobs for the operation of nuget.org.

  1. Open .\NuGet.Jobs.sln using Visual Studio

  2. Each job would be an exe with 2 main classes Program and Job

  3. Program.Main should simply do the following and nothing more

    var job = new Job();
JobRunner.Run(job, args).Wait();

  4. Job class must inherit JsonConfigurationJob. This job based provides some dependency injection setup and has you set configuration in a JSON file.

Most jobs can be run locally with a -Configuration {path_to_json} command line argument. Not all follow this pattern. Check the implementation in Program.cs or the README.md next to the .csproj project file for job-specific information.

Deploy

Deploy to Azure

You will find instructions on how to deploy the Gallery to Azure here.

Deploy locally

After you succeed in running the NuGet Gallery, you can create a publish profile to deploy locally (such as your local Windows computer).

The steps are:

  1. Select the NuGetGallery project in Solution Explore of Visual Studio.
  2. Right click the project, and then click Publish in the pop-up menu. Create a publish profile and make sure the Target is set to Folder.
  3. Copy the contents of the Target Location to any folder you want. For the following example, assume the folder is C:\ContosoSoftware\NuGetGallery.
  4. Execute the command below to start the web app (note that the parameter /path of iisexpress.exe only supports absolute paths on Windows). 
    "C:\Program Files\IIS Express\iisexpress.exe" /path:C:\ContosoSoftware\NuGetGallery

Now you can access the local website with a web browser. The URL is https://localhost.

After you deploy it, you don't need using Visual Studio to run it anymore.

Contribute

If you find a bug with the gallery, please visit the Issue tracker and create an issue. If you're feeling generous, please search to see if the issue is already logged before creating a new one.

When creating an issue, clearly explain

  • What you were trying to do.
  • What you expected to happen.
  • What actually happened.
  • Steps to reproduce the problem.

Also include any information you think is relevant to reproducing the problem such as the browser version you used. Does it happen when you switch browsers. And so on.

Submit a patch

Before starting work on an issue, either create an issue or comment on an existing issue to ensure that we're all communicating. We have a list of items that are up for grabs and you can start working on (but always ping us beforehand).

To contribute to the gallery, make sure to create a fork first. Make your changes in the fork following the Git Workflow. When you are done with your changes, send us a pull request.

The Git Workflow

This is the Git workflow we're currently using:

Setting up

Clone and checkout the dev branch.

Visual Studio may modify the applicationhost.config file. You can force git to ignore changes to this file with:

git update-index --assume-unchanged .vs/config/applicationhost.config

You can undo this with this command:

git update-index --no-assume-unchanged .vs/config/applicationhost.config

This should help prevent unwanted file commits.

When starting a new feature/unit of work.

  1. Pull the latest. Begin by pulling to make sure you are up-to-date before creating a branch to do your work This assumes you have no local commits that haven't yet been pushed (i.e., that you were previously up-to-date with origin).

    git checkout dev
git pull dev

  2. Create a topic branch to do your work. You must work in topic branches to help us keep our features isolated and easily moved between branches. Our policy is to start all topic branches off of the 'dev' branch. Branch names should use the following format '[user]-[bugnumber]'. If there is no bug yet, create one and assign it to yourself!

    git checkout dev
git checkout -b billg-123

  3. Do your work. Now, do your work using the following highly accurate and efficient algorithm :)

    1. Make changes.

    2. Test your changes (you're practicing TDD, right?)

    3. Add your changes to git's index.

       git add -A

    4. Commit your changes.

       git commit -m "<description of work>"

    5. if (moreWorkToDo) go to #3.1 else go to #4.

  4. Start a code review. Start a code review by pushing your branch up to GitHub (git push origin billg-123) and creating a Pull Request from your branch to dev. Wait for at least someone on the team to approve the PR.

  5. Merge your changes in to dev. Click the bright green "Merge" button on your pull request! Don't forget to delete the branch afterwards to keep our repo clean.

    If there isn't a bright green button... well, you'll have to do some more complicated merging:

    git checkout dev
git pull origin dev
git merge billg-123
... resolve conflicts ...
git push origin dev

  6. Be ready to guide your change through our deployed environments. Your change will make its way through the DEV (dev.nugettest.org), INT (int.nugettest.org) and finally PROD (www.nuget.org). Be prepared to fix additional bugs!
