For SUSI Web Chat, I needed a query parameter which can be passed to the components directly to activate the SUSI dreams in my textarea using just the URL which is not easy when one is using react-router. React URL Query is a package for managing state through query parameters in the URL in React. It integrates well with React Router and Redux and provides additional tools specifically targeted at serializing and deserializing state in URL query parameters. So for example, if one wants to pass some parameters to populate in your component directly through the URL, you can use react-url-query. Eg. http://chat.susi.ai/?dream=fossasia will populate fossasia in our textarea section without actually typing the term textarea. So this in the URL, Will produce this in the textarea, To achieve this. the following steps are required: First we proceed with installing the packages (Dependencies  - history) npm install history --save npm install react-url-query --save   We then instantiate a history in our component where we want to listen to the parameters like the following code. Our class ChatApp is where we want to pass the params. ChatApp.react.js import history from '../history'; //Import the history object from the History package. // force an update if the URL changes inside the componentDidMount function componentDidMount() { history.listen(() => this.forceUpdate()); }  Next, we define the props of the parameters in our Message Section. For that we need the following props- urlPropsQueryConfig - this is where we define our URLConfig Static proptypes - the query param to which we want to pass the value, so for me it’s dream. The defaultProps when no such value is being passed to our param should be left a blank. And then we finally assign the props. This is then passed to the Message Composer Section from where we receive the value passed. MessageSection.react.js // Adding the UrlConfig const urlPropsQueryConfig = { dream: { type: UrlQueryParamTypes.string } }; // Defining the query param inside our ClassName static propTypes = { dream: PropTypes.string } // Setting the default param static defaultProps = { dream: '' } //Assigning the props inside the render() function const { dream } = this.props; //Passing the dream to the MessageComposer Section <MessageComposer threadID={this.state.thread.id} theme={this.state.darkTheme} dream={dream} /> //Exporting our Class export default addUrlProps({ urlPropsQueryConfig })(ClassName); Next we update the Message Composer section by the props we had passed. For this we first check if the props are null, we don’t populate it in our textarea if it is, otherwise we populate the textarea with the value ‘dream + props.dream’ so the value passed in the URL will be prepend by a word dream to enable the ‘dream value’ in our textarea. The full file is available at MessageComposer.js //Add Check to the constructor constructor(props) { super(props); this.state = {text: ''}; if(props.dream!==''){ //Setting the text as received ‘dream dreamPassed’ this.state= {text: 'dream '+ props.dream} } } // Populate the textarea <textarea name="message" value={this.state.text} onChange={this._onChange.bind(this)} onKeyDown={this._onKeyDown.bind(this)} ref={(textarea)=> { this.nameInput = textarea; }} placeholder="Type a message..." /> // Add props to…

SUSI can be taught to give responses from APIs as well. I made use of an API called Datamuse which is a premier search engine for English words, indexing 10 million unique words and phrases in more than 1000 dictionaries and glossaries. 1. First, we head towards creating our dream pad for creating rules for the skill. To do this we need to create a dream at dream.susi.ai and give it a name, say dictionary. 2. After that one needs to go to the API and check the response generated. 3. Going through the docs of the API, one can create various queries to produce informative responses as follows - Word with a similar meaning. define *| Meaning of *| one word for * !console: $word$ { "url":"https://api.datamuse.com/words?ml=$1$", "path":"$.[0]" } eol Word related to something that start with a given letter. word related to * that start with the letter * !console: $word$ { "url":"https://api.datamuse.com/words?ml=$1$&sp=$2$*", "path":"$.[0]" } eol Word that sound like a given word.. word that sound like *|sounding like * !console: $word$ { "url":"https://api.datamuse.com/words?sl=$1$", "path":"$.[0]" } eol Words that are spelled similarly to a given word. words that are spelled similarly to *| similar spelling to *| spelling of * !console: $word$ { "url":"https://api.datamuse.com/words?sp=$1$", "path":"$.[0]" } eol Word that rhyme with a given word. rhyme *| word rhyming with * !console: $word$ { "url":"https://api.datamuse.com/words?rel_rhy=$1$", "path":"$.[0]" } eol Adjectives that are often used to describe a given word. adjective to describe *|show adjective for *|adjective for * !console: $word$ { "url":"https://api.datamuse.com/words?rel_jjb=$1$", "path":"$.[0]" } eol Suggestions for a given word. suggestions for *| show words like *| similar words to * | words like * !console: $word$ { "url":"https://api.datamuse.com/sug?s=$1$", "path":"$.[0]" } eol This is a sample query response for define * To create more dictionary skills go to http://dream.susi.ai/p/dictionary and add skills from the API.

To embed SUSI’s API Service in a chat-like system, I needed a view which could populate the content dynamically and maintain the state of the Application at the same time. Flux follows a unidirectional data flow path and I used this feature to the advantage of the Chat Application to maintain the real time state of the Chat View. A Flowchart model of Flux looks like   src: https://github.com/facebook/flux Flux uses a dispatcher service to render its views, thus making the data flow in a unidirectional path. When a user reacts with a React view (here through the TextArea in the chat system), the view propagates an action through the dispatcher service, to the various stores that hold the application’s data and finally update the views that are affected. Here’s another flowchart model from the website which helps one understand the model in a better way. For the current Chat Application, I used a single Message Store which contained all the event listeners to detect any change in the view. For example, when I send a “Hey” to SUSI, an action is called to Dispatch this message to the Message Store with an ActionType  “CREATE_MESSAGE”. This store then renders the message in the Message Section View. Here is an example snippet from the Actions.js file which performs an action of type CREATE_MESSAGE and dispatches the messages to the MessageStore.js. export function createMessage(text, currentThreadID) { let message = ChatMessageUtils.getCreatedMessageData(text, currentThreadID); ChatAppDispatcher.dispatch({ type: ActionTypes.CREATE_MESSAGE, message }); ChatWebAPIUtils.createMessage(message); }; The response from the message is generated as soon as another ActionType named “CREATE_SUSI_MESSAGE” is dispatched to the store, thereby rendering the SUSI’s response generated in the view. The file ChatConstants.js which declares all the ActionTypes. import keyMirror from 'keymirror'; export default { ActionTypes: keyMirror({ CREATE_MESSAGE: null, RECEIVE_RAW_CREATED_MESSAGE: null, CREATE_SUSI_MESSAGE: null, RECEIVE_SUSI_MESSAGE: null, RECEIVE_RAW_MESSAGES: null }) }; To get the message up on the view, I have used the following utils to call the API, render the messages to the view and call the different actions. Here’s a code snippet from ChatMessageUtils.js export function createMessage(message) { ChatExampleDataServer.postMessage(message, createdMessage => { Actions.receiveCreatedMessage(createdMessage, message.id); }); ChatExampleDataServer.postSUSIMessage(message, createdMessage => { Actions.createSUSIMessage(createdMessage, message.threadID); }); }; To know more about the project join us on Gitter at gitter.im/fossasia/susi_webchat, or to contribute go to https://github.com/fossasia/chat.susi.ai/.
