Fable.Package.SDK 1.3.0

Fable.Package.SDK

Fable.Package.SDK is a set of MSBuild targets and tasks that help you build and package Fable projects.

Features 🚀

• Automatically add Fable specific tags to PackageTags based on the FablePackageType property
• Automatically include F# source files in the package if needed
• Check that at least one Fable target is defined in the PackageTags property
• Set GenerateDocumentationFile to true
• Set up your package for improving IDE experiences by setting:
  • DebugType to embedded
  • EmbedUntrackedSources to true

Installation

.NET CLI

dotnet add package Fable.Package.SDK

This will add the package to your project file.

<PackageReference Include="Fable.Package.SDK" Version="x.y.z" />
    <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    <PrivateAssets>all</PrivateAssets>
</PackageReference>

These rules are necessary to ensure that the package is not included in the final package, you don't want you package to depend on Fable.Package.SDK at runtime.

Paket

# In your paket.dependencies
nuget Fable.Package.SDK copy_local: true

# In your paket.references
Fable.Package.SDK

Usage

1. Set the FablePackageType property

Set the FablePackageType property in your project file to one of the following values:

• library: If your package is a library that can be used by Fable.

  Examples of libraries could be Fable.Promise, Elmish, Thoth.Json, Feliz

  This will include the source files in the package.

• binding: If your package consist of a set of API to make a native library available

  For example:

  • A package which makes an NPM package API available
  • A package which makes the Browser API available
  • A package which makes a cargo package API available

  <br/>

  Only the DLL will be included in the package, allowing for a faster build and smaller package size.

2. Specify the targets

Choose one or more of the following tags:

• fable-dart: Dart is supported by the package
• fable-dotnet: .NET is supported by the package
• fable-javascript: JavaScript is supported by the package
• fable-python: Python is supported by the package
• fable-rust: Rust is supported by the package
• fable-all: Package is compatible with all Fable targets.

[!WARNING] A package can be compatible with all targets if it depends only on packages that are also compatible with all targets.

A package compatible with all targets cannot be a binding, as these are target-specific.

Example:

If your package supports only JavaScript you need to use fable-javascript

If your package supports both JavaScript and Python, you need to use fable-javascript and fable-python

Example of use case

If your package is a binding which target JavaScript you need to write:

<PropertyGroup>
    <PackageTags>fable-javascript</PackageTags>
    <FablePackageType>binding</FablePackageType>
</PropertyGroup>

If your package is a library which targets JavaScript and Python you need to write:

<PropertyGroup>
    <PackageTags>fable-javascript;fable-python</PackageTags>
    <FablePackageType>library</FablePackageType>
</PropertyGroup>
