You can use GitHub API to get the sloc like the following function

function getSloc(repo, tries) {

    //repo is the repo's path
    if (!repo) {
        return Promise.reject(new Error("No repo provided"));
    }

    //GitHub's API may return an empty object the first time it is accessed
    //We can try several times then stop
    if (tries === 0) {
        return Promise.reject(new Error("Too many tries"));
    }

    let url = "https://api.github.com/repos" + repo + "/stats/code_frequency";

    return fetch(url)
        .then(x => x.json())
        .then(x => x.reduce((total, changes) => total + changes[1] + changes[2], 0))
        .catch(err => getSloc(repo, tries - 1));
}

Personally I made an chrome extension which shows the number of SLOC on both github project list and project detail page. You can also set your personal access token to access private repositories and bypass the api rate limit.
