Sample Node.js App integrating SAWO for authentication
- Install
expressby running
npm install express- Make some endpoints in
index.jsfile and serve your html files
const express = require("express");
const app = express();
const path = require("path");
app.use(express.static(path.join(__dirname, "public")));
app.get("/", (req, res) => {
res.sendFile(__dirname + "/index.html");
});
app.get("/login", (req, res) => {
res.sendFile(__dirname + "/public/login.html");
});
app.get("/success", (req, res) => {
res.sendFile(__dirname + "/public/success.html");
});
app.listen("3000", console.log("Listening on port 3000."));- The body of the login page should look like this for showing the SAWO login form
<body>
<div id="sawo-container" style="height: 300px; width: 300px"></div>
<script src="https://websdk.sawolabs.com/sawo.min.js"></script>
<script>
// Fetching payload from sessionStorage
const payload = sessionStorage.getItem("payload");
if (payload) {
// If the payload is available, that means the user has logged in already.
// So redirecting back to "/login"
window.location.href = "/success";
}
var config = {
// should be same as the id of the container created on 3rd step
containerID: "sawo-container",
// can be one of 'email' or 'phone_number_sms'
identifierType: "email",
// Add the API key copied from 2nd step
apiKey: "Your API Key",
// Add a callback here to handle the payload sent by sdk
onSuccess: (payload) => {
// Storing the payload in sessionStorage
sessionStorage.setItem("payload", JSON.stringify(payload));
// Redirecting to "/success"
window.location.href = "/success";
},
};
var sawo = new Sawo(config);
sawo.showForm();
</script>
</body>- You can store the payload to the sessionStorage and can take actions according to that
- Demo body for the success.html file
<body>
<h2 id="login" style="text-align: center">
You Have Logged In Successfully !
</h2>
<script>
// Fetching payload from sessionStorage
const payload = sessionStorage.getItem("payload");
// Checking if the payload is available or not
if (payload) {
// If the payload is available then console.log the payload
console.log("Payload : " + payload);
} else {
// If the payload isn't available, that means the user hasn't logged in yet.
// So redirecting back to "/login"
window.location.href = "/login";
}
</script>
</body>
