Automating the process

Sharing a tip after it has been added should be automated.

I've done a little research and came up with this pseudo(javascript)code to use with GitHub Webhooks. It only includes Twitter status updates because AFAIK Instagram does not have a public API to allow posting images. I can build a fully functional script to run on Amazon Lambda or similar if it is indeed what you guys need.

// const repo = magical GitHub API object

async function handleGithubPushEvent(pushEventData) {

    // See [1] below
    const masterWantsUsToShare = pushEventData.commits.some(commit =>
        commit.message.contains('!share')
    );

    if (!masterWantsUsToShare) {
        return;
    }

    // See [2] below
    const tree = await repo.getTree('/');

    const latestCodeDirectory = tree.sortByNameDesc()
        .find(directory => directory.isCodeDirectory);

    // See [3] below
    const meta = await.repo.getFile(latestCodeDirectory.path + '/meta.json');
    const image = await.repo.getFile(latestCodeDirectory.path + '/screenshot.png');

    // See [4] below
    const mediaID = await twitterAPI.uploadMedia(image);

    // See [5] below
    await twitterAPI.postTweet({
        tweet: meta.tweet,
        media: mediaID,
    });
}

Note on Instagram: There are private API implementations around but I don't know what risks they might bring up. See for yourself and take your chances if you'd like 😛 https://github.com/huttarichard/instagram-private-api
