GitHub Action - Releases API

This GitHub Action uploads release assets using Upload a release asset. actions/upload-release-asset is great, but it is no longer maintained. So, I create this action.

FEATURE

The action is compatible with actions/upload-release-asset, however it has some additional features.

• You can upload multiple assets in one step by using glob patterns
• The actions guesses the content-type from the extensions

SYNOPSIS

Upload assets when a release has been created

You can upload assets when a release has been created.

on:
  release:
    types:
      - created

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      # steps for building assets
      - run: echo "REPLACE ME!" > assets.txt

      - uses: shogo82148/actions-upload-release-asset@v1
        with:
          upload_url: ${{ github.event.release.upload_url }}
          asset_path: assets.txt

Upload assets when a tag has been created

If you want to create a release in your workflow, you can use shogo82148/actions-create-release GitHub Action.

on:
  push:
    tags:
      - "v*"

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      # steps for building assets
      - run: echo "REPLACE ME!" > assets.txt

      - name: Create a Release
        id: create_release
        uses: shogo82148/actions-create-release@v1

      # A release created by shogo82148/actions-create-release is alway draft here.
      # So users may not see an empty release.

      - name: Upload Assets
        uses: shogo82148/actions-upload-release-asset@v1
        with:
          upload_url: ${{ steps.create_release.outputs.upload_url }}
          asset_path: assets.txt

      # shogo82148/actions-create-release publishes the release in the end of the job.
      # Users now can download `assets.txt` from the release page.

Inputs

The URL for uploading assets to the release.

The path to the asset you want to upload. You can use glob patterns here.

asset_name

The name of the asset you want to upload. The file name of asset_path is used by default.
