API Specs - HackMD

# API Specs Assume that all nodes have direct connections to one another. (It simplifies the process a whole lot more) ## Post Propagation There are two types of posts that are propagated. ### Regular Posts The **source** post id should match the **origin** post id if we receive a post through the inbox that is not a shared post. In this case, we add a post with the same `id` and all other properties of the received post ### Shared Posts The **source** of the post gives the api url to the post that the share button was clicked. In our system, the author id and post id of the `source` is the author who SHARED the post and their copy post id. This way you can track who actually shared the post for the following feeds. (Since all other fields are of the original post that was shared with no ref to who shared the post) ## Likes I'm not totally set on this yet, and I'd love to hear how you guys would approach this. My approach is kinda like a proxy in a sense? ### Liking a Local Post Create a like object locally, and then that's it. ### Liking a Remote Post Send a like object to the post’s origin author inbox. The origin node is responsible for storing and sending out all likes. When a request is made on your node to fetch the likes of a post that originated from a remote node, it should internally send a request to the remote node and return the contents back to your original request. ## Comments This follows the same system as likes basically. Comments and stored on the original node that created the post. ## Friends/Following ### Following: - A remote author sends an inbox payload to the remote host. If the remote author accepts the request, a Following object is created on the remote node. ### Unfollowing: - When unfollowing an author, the author that was unfollowed should be sent an inbox message stating that they were unfollowed. (Should be of the type "Unfollow") - Additionally, after accepting/rejecting a friend request, the node should send back a "FollowResponse" inbox message. - See Friends/Follow Requests down below for more information as to the contents of the inbox message. - 1 Follow ```json { "type": "Follow", "summary":"Greg rejected your friend request.", "actor":{ "type":"author", "id":"http://127.0.0.1:5454/authors/1d698d25ff008f7538453c120f581471", "url":"http://127.0.0.1:5454/authors/1d698d25ff008f7538453c120f581471", "host":"http://127.0.0.1:5454/", "displayName":"Greg Johnson", "github": "http://github.com/gjohnson", "profileImage": "https://i.imgur.com/k7XVwpB.jpeg" }, "object":{ "type":"author", "id":"http://127.0.0.1:5454/authors/9de17f29c12e8f97bcbbd34cc908f1baba40658e", "host":"http://127.0.0.1:5454/", "displayName":"Lara Croft", "url":"http://127.0.0.1:5454/authors/9de17f29c12e8f97bcbbd34cc908f1baba40658e", "github": "http://github.com/laracroft", "profileImage": "https://i.imgur.com/k7XVwpB.jpeg" }, } ``` - Unfollow ```json { "type": "Unfollow", "summary":"Greg rejected your friend request.", "actor":{ "type":"author", "id":"http://127.0.0.1:5454/authors/1d698d25ff008f7538453c120f581471", "url":"http://127.0.0.1:5454/authors/1d698d25ff008f7538453c120f581471", "host":"http://127.0.0.1:5454/", "displayName":"Greg Johnson", "github": "http://github.com/gjohnson", "profileImage": "https://i.imgur.com/k7XVwpB.jpeg" }, "object":{ "type":"author", "id":"http://127.0.0.1:5454/authors/9de17f29c12e8f97bcbbd34cc908f1baba40658e", "host":"http://127.0.0.1:5454/", "displayName":"Lara Croft", "url":"http://127.0.0.1:5454/authors/9de17f29c12e8f97bcbbd34cc908f1baba40658e", "github": "http://github.com/laracroft", "profileImage": "https://i.imgur.com/k7XVwpB.jpeg" }, } ``` - FollowResponse ```json { "type": "FollowResponse", "summary":"Greg rejected your friend request.", "actor":{ "type":"author", "id":"http://127.0.0.1:5454/authors/1d698d25ff008f7538453c120f581471", "url":"http://127.0.0.1:5454/authors/1d698d25ff008f7538453c120f581471", "host":"http://127.0.0.1:5454/", "displayName":"Greg Johnson", "github": "http://github.com/gjohnson", "profileImage": "https://i.imgur.com/k7XVwpB.jpeg" }, "object":{ "type":"author", "id":"http://127.0.0.1:5454/authors/9de17f29c12e8f97bcbbd34cc908f1baba40658e", "host":"http://127.0.0.1:5454/", "displayName":"Lara Croft", "url":"http://127.0.0.1:5454/authors/9de17f29c12e8f97bcbbd34cc908f1baba40658e", "github": "http://github.com/laracroft", "profileImage": "https://i.imgur.com/k7XVwpB.jpeg" }, // Was the friend request rejected or accepted?

Remember, the way remote server becomes aware of local posts is by local server pushing those posts to inbox, not by remote server pulling. - Be aware that Posts can be images that need base64 decoding. - posts can also hyperlink to images that are public - Example format: ```json { "type":"post", // title of a post "title":"A post title about a post about web dev", // id of the post "id":"http://127.0.0.1:5454/authors/9de17f29c12e8f97bcbbd34cc908f1baba40658e/posts/764efa883dda1e11db47671c4a3bbd9e" // where did you get this post from?

But they are encoded as base64 data. You can inline an image post using a data url or you can use this shortcut to get the image if authenticated to see it. - URL/api/authors/{AUTHOR_ID}/posts/{POST_ID}/image - GET [local, remote] get the public post converted to binary as an iamge - return 404 if not an image - This end point decodes image posts as images.
