海外TECH	DEV Community	Node.js server-side authentication: Tokens vs. JWT	https://dev.to/logrocket/nodejs-server-side-authentication-tokens-vs-jwt-9bd	Node js server side authentication Tokens vs JWTWritten by Destiny Erhabor️In modern web development authentication is a critical part of securing applications The two most popular approaches include server side authentication using tokens and client side authentication using JSON Web Tokens JWT Both methods have their own unique advantages and disadvantages and deciding which one to use depends on the requirements of your specific application In this article we ll compare both methods and highlight the benefits and drawbacks of each Let s get started Jump ahead Stateless vs stateful authentication What are server side tokens Advantages of using server side authentication Disadvantages of server side authentication Server side authentication with a Node js application Server side authentication Use cases What is JWT authentication Advantages of JWT authentication Disadvantages of JWT authentication JWT authentication with a Node js application JWT Use cases Server side tokens vs JWT Summary Stateless vs stateful authenticationIn web applications authentication is the process of verifying the identity of a user who wants to access a restricted resource You can use several different kinds of authentication like username and password authentication social login or biometric authentication Stateless authenticationIn stateless authentication the server doesn t store any session information about the user Instead each request that the user makes to the server contains all the necessary information for authentication typically in the form of a JWT The server then validates the token and responds accordingly Stateless authentication is popular in modern web applications because it is scalable and can be used with the microservices architecture Stateful authenticationIn stateful authentication the server stores session information about the user in a database or an in memory cache When the user logs in the server creates a session ID and stores it on the server side This session ID is then used to authenticate subsequent requests made by the user Stateful authentication is less scalable than stateless authentication because it requires the server to maintain state which can become an issue with large user bases What are server side tokens Using server side tokens which is also called session based authentication is an example of stateful authentication that involves storing user authentication data on the server Upon successful authentication the server generates a unique token for the user which is then stored in the server s memory or database The token is then sent back to the client either as a cookie or in the response body Server side authentication with tokens involves creating a unique session token for each user when they log in The token is stored on the server side and used to authenticate subsequent requests from the same user In contrast client side authentication using JWT involves issuing a signed token to the client upon successful login which is then stored on the client side and sent back to the server with each subsequent request Advantages of using server side authentication Easy to invalidateServer side authentication is easy to invalidate because we have complete control over the session data stored on the server If we suspect any fraudulent activity we can quickly terminate a user s session or revoke a token thereby providing an additional layer of security No storage limitationsUnlike client side authentication where storage space is limited to cookies or local storage we can store any amount of session data on the server with server side authentication This makes it easier to store large amounts of data like user preferences or history Better for complianceTo meet compliance regulations some regulatory bodies require that session data be stored on the server side This is aimed at enhancing data security privacy and control over sensitive information within a controlled and secure environment In these cases server side authentication is a better option Some examples include the Payment Card Industry Data Security Standard PCI DSS and the Health Insurance Portability and Accountability Act HIPAA No need for re authenticationWith server side authentication you don t need to re authenticate the user on every request which can improve your application s performance Disadvantages of server side authentication Scalability issuesAs the number of users and sessions increases storing all the session data on the server can cause scalability issues It requires more memory and CPU resources which can cause slower response times and decrease performance overall ComplexityServer side authentication can be complex to implement and maintain especially if you need to store the session data across multiple servers or instances It requires more code configuration and infrastructure CostBecause it requires more resources and infrastructure server side authentication can be more expensive than client side authentication No offline accessSince all the session data is stored on the server there is no offline access available which can be a disadvantage in some scenarios Server side authentication with a Node js application Let s review a simple code implementation of the server side authentication method First we need to install express session and the Express package for Node js We can do so by running the code below npm install express express sessionNext we ll create a simple index js file const express require express const session require express session const app express Dummy user object to demonstrateconst users id username john password password id username jane password password Array to hold blacklisted user IDsconst blacklistedUsers Middleware to parse JSON request bodiesapp use express json Middleware to initialize the sessionapp use session secret mysecretkey resave false saveUninitialized true Login endpointapp post login req res gt const username password req body Find the user by username and password const user users find u gt u username username amp amp u password password if user if blacklistedUsers includes user id return res status send User is blacklisted Save the user ID in the session req session userId user id Send the user object back to the client res json user else Send an error response if the user is not found res status json message Invalid username or password Logout endpointapp post logout req res gt Destroy the session to log the user out req session destroy Send a success response res json message Logged out successfully Protected endpointapp get profile req res gt console log req session userId Check if the user is logged in by checking if the user ID is present in the session if req session userId Find the user by ID const user users find u gt u id req session userId Send the user object back to the client res json user else Send an error response if the user is not logged in res status json message Unauthorized Blacklist endpoint app post blacklist req res gt const userId req body blacklistedUsers push userId res send User ID userId blacklisted Start the serverapp listen gt console log Server started on port The code above implements server side authentication using Express and the express session middleware It defines a simple login and logout endpoint and a protected profile endpoint that can only be accessed by authenticated users When a user logs in with a valid username and password their user ID is saved in the session This user ID retrieves the user object from the array of dummy users and sends it back to the client When the user logs out their session is destroyed The protected profile endpoint checks if the user is logged in by checking if their user ID is present in the session If the user is not logged in an error response is sent Otherwise the user object is retrieved from the array of dummy users and sent back to the client One drawback of this implementation is that the session and blacklisted user is stored server side in memory which can become a scalability issue as the number of users increases Additionally if the server crashes or restarts all active sessions will be lost To avoid these issues you could use a distributed caching system like Redis to store sessions instead of storing them in memory Server side authentication Use cases Let s review the scenarios where server side authentication using tokens is generally preferable Security is a top priorityBecause the server has full control over the creation and management of session tokens it s easier to implement advanced security measures like IP blocking rate limiting and token revocation The application requires real time updatesIf your application requires real time updates or notifications server side authentication can be more efficient because the server can push updates to the client based on the session ID Scalability is a concernIn server side authentication the session state is stored on the server side which can be scaled horizontally across multiple servers using tools like Redis or Memcached What is JWT authentication JWT authentication is a stateless token based authentication method It involves generating a token containing the user s identity information which is then sent to the client to be stored The client then sends this token with every request to the server to authenticate the user To ensure that the user is authorized to access the requested resource the token is verified on the server To implement client side authentication using JWT you ll need to issue a signed token to the client upon successful login and store it on the client side You ll also need to include the token with each subsequent request to authenticate the user Advantages of JWT authentication StatelessSince the token contains all the necessary information to authenticate the user the server doesn t need to maintain any session data or database queries JWT is a stateless authentication method that can simplify server maintenance and reduce resource usage ScalabilityJSON Web Tokens allow for scaling out server resources because the server doesn t need to maintain any state data Cross domainThe token is self contained and doesn t require accessing the server for validation so JWT can be used across different domains Disadvantages of JWT authentication Token sizeIn JWT authentication the token size can be large This can impact performance negatively especially if the token is sent with every request Security risksIf a token is compromised an attacker can impersonate the user and gain access to protected resources Additionally if the token is not properly signed an attacker can modify the data contained in the token Token expirationIf the token doesn t expire it can be used indefinitely However if the token expires too frequently it can inconvenience the users who would have to log in frequently Balancing the token expiration time is a critical aspect to consider JWT authentication with a Node js application The code below shows an example implementation of JWT authentication using Node js and the Express framework const express require express const jwt require jsonwebtoken const app express Dummy user object to demonstrateconst users id username john password password id username jane password password Secret key to sign and verify JWTsconst secretKey mysecretkey Login endpointapp post login req res gt const username password req body Find the user by username and password const user users find u gt u username username amp amp u password password if user Create a JWT token with the user ID as the payload const token jwt sign userId user id secretKey Send the token back to the client res json token else Send an error response if the user is not found res status json message Invalid username or password Protected endpointapp get profile req res gt Get the authorization header from the request const authHeader req headers authorization if authHeader Extract the JWT token from the authorization header const token authHeader split try Verify the JWT token with the secret key const decodedToken jwt verify token secretKey Get the user ID from the decoded token const userId decodedToken userId Find the user by ID const user users find u gt u id userId Send the user object back to the client res json user catch error Send an error response if the token is invalid res status json message Invalid token else Send an error response if the authorization header is not present res status json message Unauthorized Start the serverapp listen gt console log Server started on port The code uses the jsonwebtoken library to generate and verify JSON Web Tokens It provides two endpoints login and profile The login endpoint expects a POST request with the username and password of a user in the request body It finds the user in the users array and creates a JWT token with the user ID as the payload It then sends the token back to the client as a JSON object The profile endpoint expects a GET request with an authorization header containing a valid JWT token It extracts the token from the header and verifies it with the secret key If the token is valid it extracts the user ID from the payload and finds the user in the users array It then sends the user object back to the client as a JSON object JWT Use cases Authentication and authorizationWe can use JWTs to securely transmit authentication and authorization data between the client and server By including a user s identity and permissions in a JWT a server can verify that a user is authorized to access certain resources Single sign on SSO JWTs are a great choice to implement single sign on SSO where a user logs into a single application and is then able to access other applications without having to log in again The JWT can securely transmit the user s identity and authentication state between applications Mobile applicationsWhere traditional session based authentication methods may not be feasible you can use JWTs to authenticate and authorize users in mobile applications The JWT can be stored on the device and used to authenticate the user with the server on subsequent requests MicroservicesYou can use JWTs to authenticate and authorize requests between microservices in a distributed system Each microservice can use the JWT to verify that requests are coming from a trusted source and that the user is authorized to access the requested resource Server side tokens vs JWT Summary TokensJWTStored server sideStored client sideEasily revokedDifficult to revokeRequire server side storageStatelessSuitable for real timeBetter for mobile or SPAUpdatesMultiple domains or microservicesScalable with Redis or MemcachedRequires distributed signing or validationMore secureFaster and easier to implement ConclusionIn summary JWT authentication is a stateless approach that uses digitally signed tokens for secure communication It offers easy integration cross domain compatibility and additional security features However it s important to keep an eye on the token size and revocation Server side token authentication involves storing session information on the server It offers easy session management quick invalidation and control over simultaneous logins However it requires server side storage which may pose scalability challenges Choosing between JWT and server side token authentication depends on your use case security needs and scalability requirements JWT is suitable for stateless scenarios and APIs while server side tokens work best for session based authentication in web applications I hope you enjoyed this article and be sure to leave a comment if you have any questions

Bluetooth speakers under Usually it s down to for Prime members which is a discount that matches the lowest price It gives bright dynamic finesse to music and delivers a significant amount of bass for its size It s about the size of a clutch bag and even has a small loop strap to further the comparison And of course it s IP rated so it can handle the elements Ultimate Ears Wonderboom The Wonderboom from Ultimate Ears is currently percent off for Prime Day dropping it down to instead of the usual That s the lowest price we ve seen in a while matching the all time low it hit just before Black Friday last year In our tests the Wonderboom delivered the biggest sound of any speakers in its size range plus it has a cute design with a strap and comes in bright blue hot pink or a more sedate gray note that the black colorway isn t discounted Anker Soundcore Motion Anker s Soundcore Motion is normally but is discounted to for Prime members as a Lightning Deal In our guide we said it produces good sound for the price which is even more true now It s a little heavier than you d expect and the soft touch exterior shows fingerprints but if those aren t deal breakers for you you ll enjoy bright and bassy output a connected app with EQ customization and IPX water resistance Anker Soundcore With over k positive ratings Anker s tiny but mighty Soundcore is a great buy at its usual but Prime Day savings bring it down to just for Prime members It has a IPX rating so it can handle an accidental dunk in water and the battery will deliver a claimed hours of play time Two Soundcore s can pair up for stereo sound so if the price tempts you to get a set you may as well go for it JBL Charge JBL s Charge is usually but is down to for Prime members It also made Engadgets speaker guide and has a separate tweeter and dual bass radiators for bigger sound and of course can handle a dunk in water It s got a long hour battery life and can even share some of that juice with your phone via the USB C port JBL Boombox JBL s Boombox is for Prime Day which is off the list price We recommend the third generation of JBL s Boombox speaker in our guide because it s loud and comes in a take anywhere package This previous model offers hours of playback has a waterproof design and can recharge your phone At pounds it s big but still portable Sony SRS XPSony s party sized SRS XP Bluetooth speaker is down to after a discount for Prime Day It pumps out loud thumping beats stands over two feet tall and emits lighting effects that sync with what s playing It weighs pounds so the grab bars on the top and bottom make a lot of sense It can go for hours on a charge and offers a bit of water resistance to accidental splashes but its size and build make it less rough and tumble than other portable Bluetooth speakers Sony SRS XB EXTRA BASSThe SRS XB speaker stands a little over four inches tall and is going for just for Prime Day which is percent off its list price This is the previous model which was replaced this year by the SRS XB But if you don t have to live on the cutting edge you ll get a portable unit that s rated IP for water and dust resistance and uses Sony s Sound Diffusion Processor which is designed to deliver “rich dynamic sound Plus you can pair two for stereo effects Samsung HW QBSamsung s HW QB soundbar is currently for Prime members after a steep percent discount off its MSRP It s the runner up midrange soundbar in Engadget s guide and supports Dolby Atmos and Q Symphony which allows you to play sound from both the soundbar and your late model Samsung TV Other Samsung tech like SpaceFit and Adaptive Sound help automatically calibrate the speaker to sound better in your space Vizio Vt JThe Vizio Vt J carries a list price of but is presently for Prime Day which isn t an all time low and just off but we think this is the best budget soundbar you can buy even when it s full price It doesn t take up a lot of space and supports Bluetooth HDMI ARC eARC mm and optical connections but not WiFi It also employs DTS Virtual X which promises more three dimensional sound without requiring a bunch of extra speakers Your Prime Day Shopping Guide See all

mainstream A III Resolution is up considerably to megapixels and image quality is much improved overall Video is now on par with rivals with K at up to p with bit quality Autofocus is incredible for both video and stills and the in body stabilization does a good job The biggest drawbacks are rolling shutter that limits the use of the electronic shutter and the relatively high price ーbut the discount helps ease the latter a bit Sony A IIIAt launch I said that Sony s megapixel A III was a near perfect all around camera That still applies The already excellent point hybrid phase detect autofocus system has been updated via firmware with the real time eye and animal AF features introduced with the A A models On top of that you can shoot bursts at up to fps with continuous autofocus
