Add the download URL of an asset of your latest release
Often there is the question to get the download URL for an asset (e.g. a setup-file) of the latest release of a project. In my case I provide an executable, which includes the version number in its name together with the source as ZIP- and Tarball-archive. Others provide versioned source tarballs or executables, which are different from the Git repository source tarballs.
project-X.Y.Z-setup.exe project-X.Y.Z-src.tar.gz
Now to get the download URL(s) for the asset(s) using the GitHub API one can get and process this URL (replacing USER and PROJECT/var> with the GitHub user account and projectname accordingly):
Note, that the assets download URL is provided by the The content provided by the API is also available to Jekyll sites hosted on GitHub pages via the You'll find, that you can even access detailed author and project information. Now to get the download URL of my asset, I just access the first list entry using this: or this approach (less typing): I use this to create structured data in JSON-LD for a software application. I can even access the file size, the creation and publication date of my asset. The following shows the JSON-LD snippet I add to one of my GitHub project pages (I replaced fixed content with dots): If there is more than one asset (the GitHub repository source tarball and zipball are not assets) one probably has to use a more flexibale approach then accessing the first list entry via and create the download URL like this Because it is common to tag the version as Using the approach above one can even loop over https://api.github.com/repos/USER/PROJECT/releases/latest
browser_download_url object in the assets objects list:
{
...
"assets": [
{
...
"browser_download_url": "...",
...
}
]
}
site.github namespace. You can easily check all the content of this namespace using this approach (somewhere in your code):{{ site.github | inspect }}
{{ site.github.latest_release.assets[0].browser_download_url }}
{% assign release = site.github.latest_release %}
{{ release.assets[0].browser_download_url }}
{% assign release = site.github.latest_release %}
{
"@context": "http://schema.org/",
"@type": "SoftwareApplication",
"name": "...",
"softwareVersion": "{{ release.tag_name | strip | remove: 'v' }}",
"alternateName": [
"...",
"{{ release.name }}"
],
"description": "...",
"applicationCategory": "...",
"inLanguage": ["..", ".."],
"operatingSystem": [
"...",
"..."
],
"downloadUrl": "{{ release.assets[0].browser_download_url }}",
"fileSize": "{{ release.assets[0].size | divided_by: 1024 }}",
"releaseNotes": "{{ release.html_url }}",
"license": "...",
"url": "{{ site.github.repository_url }}",
"datePublished": "{{ release.published_at }}",
"dateCreated": "{{ release.created_at }}",
"author": {%- include json/person.json -%},
"publisher": {%- include json/publisher.json -%}
}
asset[0] as shown above. If there are several assets and the asset file name is created the same way for every release but includes the version number (see the file name examples from the beginning of this post), there is another approach, that might be to used. One can process:
{{ site.github.latest_release.tag_name }}
{{ site.github.releases_url }}/download/latest/foo-{{ site.github.latest_release.tag_name | strip | remove 'v' }}-setup.exe
{{ site.github.releases_url }}/download/latest/foo-{{ site.github.latest_release.tag_name | strip | remove 'v' }}-src.tar.gz
vX.Y.Z the leading v is removed from the version tag in the examples above.site.github.releaes and create a changelog/news page automatically for all releases! Maybe you can share your ideas about the suggested approaches on my GIST page.
