How to get list of trending github repositories by github api?

GitHub seems to use their API to write the trending page and don't present it back as a particular API. You need to use the Repository Search API. I've followed the examples on this page, which could solve your needs by:

# We'll use the `date` command to get the date for "7 days ago"
$ date -v-7d '+%Y-%m-%d'
# => 2013-07-15

curl -G https://api.github.com/search/repositories --data-urlencode "sort=stars" --data-urlencode "order=desc" --data-urlencode "q=language:java"  --data-urlencode "q=created:>`date -v-7d '+%Y-%m-%d'`"

And then go from there. You can also make your life a lot easier by installing jq on OS X or other platforms to get prettier output:

curl -G https://api.github.com/search/repositories --data-urlencode "sort=stars" --data-urlencode "order=desc" --data-urlencode "q=language:java"  --data-urlencode "q=created:>`date -v-7d '+%Y-%m-%d'`" | jq ".items[0,1,2] | {name, description, language, watchers_count, html_url}"

}

Currently there is no GitHub API to get list of trending repositories. The only way is to crawl items from web page by selectors. You can open https://github.com/trending in Chrome and run the following code in devtools console:

$$('ol.repo-list li h3').forEach(el => console.log(el.innerText));

This will output the list of trending repositories names. To make it more automated consider Headles Chrome or other similar tools.

Also there are several projects that already have solved this task in different languages. For example:

• vitalets/github-trending-repos
• andygrunwald/go-trending
• sheharyarn/github-trending
• etc
