Before Alexa Live 2020, I’m using ssml-tsx library to write a SSML as JSX(TSX).

But, the library is conflict to ask-sdk-jsx-for-apl.

So, I’ve made a alt library to me.

@talkyjs/ssml

It’s a lightweight library to do it. Includes just a type definition for Alexa SSML and a helper function to render SSML to string.

Install

We can use it almost the same as ask-sdk-jsx-for-apl.

$ npm install -S @talkyjs/ssml react react-dom

# (Optional) with ask-sdk-jsx-for-apl
$ npm install -S ask-sdk-jsx-for-apl

# (Optional) with TypeScript
$ npm install -D @types/react @types/react-dom

(Optional) check the tsconfig.json

We need to update these attributes like this.

...
    "jsx": "react",
    "esModuleInterop": true,
...

Write a JSX for Alexa!

Using @talkyjs/ssml and ask-sdk-jsx@for-apl, we can use JSX to make a response for Alexa request both SSML and APL.

ssml.jsx

import React from 'react'
import '@talkyjs/ssml'

export const LaunchRequestSpeech = () => {
    return (
        <speak>
            hello It's a great thing,
            and there is test. 
            <emphasis level="reduced">hello</emphasis>
            <w role="amazon:NN">aaaa</w>
            <amazon-domain name="music">Music</amazon-domain>
            <amazon-effect name="whispered">aaaa</amazon-effect>
            <amazon-emotion name="disappointed" intensity="high">aaaa</amazon-emotion>
        </speak>
    )
}

apl.jsx

import React from 'react';
import { APL, MainTemplate, Container, Text, AplDocument } from 'ask-sdk-jsx-for-apl';

export const LaunchAplDocumentFC = () => {
    const launchMessage = 'Welcome to my first JSX for APL skill!';
    return (
        <APL theme="dark">
            <MainTemplate>
                <Container
                    alignItems="center"
                    justifyContent="spaceAround">
                    <Text
                        text={launchMessage}
                        fontSize="50px"
                        color="rgb(251,184,41)" />
                </Container>
            </MainTemplate>
        </APL>
    );
}

LaunchRequest.jsx

import React from 'react'
import { renderSSMLToString } from "@talkyjs/ssml";
import { AplDocument } from "ask-sdk-jsx-for-apl";

import { LaunchAplDocumentFC } from "./apl";
import { LaunchRequestSpeech } from "./ssml";

export const LaunchRequestHandler = {
    canHandle(input) {
        return input.requestEnvelope.request.type === 'LaunchRequest'
    },
    async handle(input) {
        return input.responseBuilder
            .speak(
                renderSSMLToString(
                    <LaunchRequestSpeech />
                )
            )
            .addDirective(
                new AplDocument(
                    <LaunchAplDocumentFC />
                ).getDirective()
            )
            .getResponse()
    }
}

The response
