TS SDK v6.0.0 Migration Guide

This guide is to provide information about breaking changes and how to migrate to the Social Plus TS SDK 6.0.0 version.

Installation

Using NPM

npm i @amityco/ts-sdk@^6.0.0

Using Yarn

yarn add @amityco/ts-sdk@^6.0.0

Deprecation of RunQuery / CreateQuery

Starting from 6.0.0 we recommend using API's asynchronously. As it will soon be deprecated. Example:

// before
import { updatePost, runQuery, createQuery } from '@amityco/ts-sdk';

const query = createQuery(updatePost, 'postId', { ...updatedPost });

runQuery(query, callback);

// after v6.0.0
import { PostRepository } from '@amityco/ts-sdk'

const updatedPost = await PostRepository.updatePost('postId', { ...updatedPost });

Real Time Events

The real time events are supported via MQTT, which has a crucial difference in how it works compared to web sockets. This is, events are not broadcast-ed to all users. So this means that you only get real time event updates to those topics that you subscribe to.

Note: Some exceptions to this are message events and smart feed events. If you are unsure if subscription is required for a particular topic, check the code-snippet for that particular API for details.

There are also other limitations to getting RTE's, example: you cannot subscribe to events for a community that you are not a member of. Check documentation for full details.

You can read more about MQTT here: https://mqtt.org/

/*
 * Whenever you notice similar code block in the code snippets it indicates that you 
 * subscribing to a particular topic, which in turn let's the server know that you
 * would require real time events for this topic
*/

subscribeTopic(getUserTopic(user, SubscriptionLevels.POST), () => {
    // use callback to handle errors with event subscription
}),

Live Object

Although live objects were introduced prior to v6. All getter methods for singular objects (example getPost) will now return a subscribe-able object.

This means that if an object gets updated and you have subscribed to real time events, the object will get updated automatically via real time events.

If for your use case you don't require any real time updates, you can unsubscribe immediately. For further information about Live Object, please visit Live Object page.

Getting Real Time Updates for an Object

import { PostRepository, subscribeTopic, getPostTopic } from '@amityco/ts-sdk';
import { FC, useEffect, useState } from 'react';

const disposer: Amity.Unsubscriber[] = [];

const GetPost: FC<{ postId: string }> = ({ postId }) => {
  const [post, setPost] = useState<Amity.Post>();

  useEffect(() => {

    const unsubscribePost = PostRepository.getPost(postId, ({ data }) => {
     const { post, loading, error } = data
     
     if (post) {
       /*
       * This step is important if you wish to recieve real time updates
       * Here, you are letting the server know that you wish to recieve real time
       * updates regarding this post
       */
       disposers.push(subscribeTopic(getPostTopic(post)))
       
       setPost(post)
     }
    });
    
    disposers.push(unsubscribePost);
  }, [postId]);

  return null;
};

Getting the object only once

import { PostRepository } from '@amityco/ts-sdk';
import { FC, useEffect, useState } from 'react';

const GetPostOnce: FC<{ postId: string }> = ({ postId }) => {
  const [post, setPost] = useState<Amity.Post>();

  useEffect(() => {
    const unsubscribePost = PostRepository.getPost(postId, ({ data }) => {
     const { post, loading, error } = data
     
     if (post) {       
       setPost(post)
     }
    });
    
    unsubscribePost()
  }, [postId]);

  return null;
};

Live Collection

Although live collections were introduced prior to v6. All query methods for collection of objects (example getPosts) will now return a subscribe-able collection.

This means that if an object in the collection gets updated and you have subscribed to real time events, the collection will get updated automatically via real time events.

If for your use case you don't require any real time updates, you can unsubscribe immediately. Similar to live objects above. For further information about Live Object, please visit Live Collection page.

Getting Real Time updates for a collection

import {
  PostRepository,
  subscribeTopic,
  getUserTopic,
  getCommunityTopic,
  SubscriptionLevels,
} from '@amityco/ts-sdk';
import { FC, useEffect, useState } from 'react';

const disposers: Amity.Unsubscriber[] = [];

const GetPosts: FC<{ targetId: string; targetType: string }> = 
({ targetId, targetType }) => {
  const [posts, setPosts] = useState<Amity.Post[]>();

  useEffect(() => {
    const unsubscribe = PostRepository.getPosts(
      { targetId, targetType },
      ({ data: posts, onNextPage, hasNextPage, loading, error }) => {
        setPosts(posts);
        /*
         * this is only required if you want real time updates for each
         * post in the collection
         */
        subscribePostTopic(targetType, targetId);
      },
    );

    disposers.push(unsubscribe);

    return () => {
      disposers.forEach(fn => fn());
    };
  });

  return null;
};

const subscribePostTopic = (targetType: string, targetId: string) => {
  if (isSubscribed) return;

  if (targetType === 'user') {
    const user = {} as Amity.User; // use getUser to get user by targetId
    disposers.push(
      subscribeTopic(getUserTopic(user, SubscriptionLevels.POST), () => {
        // use callback to handle errors with event subscription
      }),
    );
    return;
  }

  if (targetType === 'community') {
    // use getCommunity to get community by targetId
    const community = {} as Amity.Community; 
    disposers.push(
      subscribeTopic(getCommunityTopic(community, SubscriptionLevels.POST), () => {
        // use callback to handle errors with event subscription
      }),
    );
  }
};

Getting paginated collection without and real time updates

import {
  PostRepository,
  subscribeTopic,
  getUserTopic,
  getCommunityTopic,
  SubscriptionLevels,
} from '@amityco/ts-sdk';
import { FC, useEffect, useState } from 'react';

const GetPosts: FC<{ targetId: string; targetType: string }> = 
({ targetId, targetType }) => {
  const [posts, setPosts] = useState<Amity.Post[]>();

  useEffect(() => {
    const unsubscribe = PostRepository.getPosts(
      { targetId, targetType },
      ({ data: posts, onNextPage, hasNextPage, loading, error }) => {
        if (posts)
          setPosts(posts);
        
        // to get next page use onNextPage()
      },
    );

    unsubscribe()
  });

  return null;
};
