User Login

Call the newSession function: API Reference

SuperTokens.newSession(ctx, userId).create();

• This will attach all relevant cookies and header to the res object.

Add session data

// sessionData is a Map<String, Object>
SuperTokens.newSession(ctx, userId).withSessionData(sessionData).create();

• sessionData is stored in your database and can contain any information.

Add JWT payload

// jwtPayload is a Map<String, Object>
SuperTokens.newSession(ctx, userId).withJWTPayload(jwtPayload).create();

• jwtPayload should not contain any sensitive information.

Example

import io.supertokens.javalin.*;

app.post("/login", ctx -> {
    // ...check for user credentials

    String userId = "User1";
    
    Map<String, Object> jwtPayload = new HashMap<>();
    jwtPayload.put("role", "admin");

    Map<String, Object> sessionData = new HashMap<>();
    sessionData.put("awesomeThings", "programming");

    SuperTokens.newSession(ctx, userId).withSessionData(sessionData)
        .withJWTPayload(jwtPayload).create();
    
    ctx.result("logged in");
});
