Installation

npm install @speechify/api-sdk

Usage

Server-Side Audio Generation

import { Speechify } from "@speechify/api-sdk";

const speechify = new Speechify({
	apiKey: "YOUR_API_KEY",
});

const text = "Hello, world!";
const response = await speechify.audioGenerate({
	input: text,
	voiceId: "george",
	audioFormat: "mp3",
});
const audio = response.audioData;

someStorage.saveFile("audio.mp3", audio);

Server-Side Auth Token Generation

import { Speechify } from "@speechify/api-sdk";

const speechify = new Speechify({
	apiKey: "YOUR_API_KEY",
});

webServer.post("/speechify-token", async (req, res) => {
	const user = req.user;
	if (!user) {
		res.status(401).send("Unauthorized");
		return;
	}
	const tokenResponse = await speechify.accessTokenIssue("audio:all");
	res.json(tokenResponse);
});

Client-Side Audio Generation

import { Speechify } from "@speechify/api-sdk";

const speechify = new Speechify();

authSystem.on("login", async () => {
	const res = await fetch("/speechify-token", {
		method: "POST",
	});
	const tokenResponse = await res.json();

	speechify.setAccessToken(tokenResponse.accessToken);
});

generateButton.addEventListener("click", async () => {
	const text = "Hello, world!";
	const response = await speechify.audioGenerate({
		input: text,
		voiceId: "george",
		audioFormat: "mp3",
	});
	const audio = response.audioData;

	const audioElement = new Audio();
	audioElement.src = URL.createObjectURL(
		new Blob([audio], { type: "audio/mpeg" }),
	);
	audioElement.play();
});

Client-Side Access Token Auto-Management

You can use the provided SpeechifyAccessTokenManager class to have the access token fully managed, including the auto-refresh before it expires.

import { Speechify, SpeechifyAccessTokenManager } from "@speechify/api-sdk";

const speechify = new Speechify();

const getToken = async () => {
	const res = await fetch("/speechify-token", {
		method: "POST",
	});
	return res.json();
};

const tokenManager = new SpeechifyAccessTokenManager(speechify, getToken, {
	isAuthenticated: authSystem.isAuthenticated,
});

authSystem.on("login", () => {
	tokenManager.setIsAuthenticated(true);
});

authSystem.on("logout", () => {
	tokenManager.setIsAuthenticated(false);
});

With this setup in place, you can use the speechify client without worrying about the access token management.
