Express JS is a web application framework that aids in the development of both single and multiple web applications.

Businesses require web applications to run business operations. A well-developed Express JS application requires a programmer who has extensive programming background, using specialized programming frameworks with many robust features. As a business owner, you need not understand technical programming behind the development of a web application. This does not prevent you from benefiting from the work the application will help you achieve. For this to be possible, you will need the services of an Express JS specialist to handle the programming for you while you focus your attention on what you understand better. This is where Freelancer.com comes in handy.

Experts in the use of Express JS frame understand the ins and outs of the frame. With your level of experience and expertise, you should be able to demonstrate to the clients that they can rely on your knowledge in handling their projects. Your profile should represent what you can offer. As the role depends solely on your competencies, it is easy to handle different clients at the same time and keep delivering quality service. As a freelancer, you will never be out of work.

    Hey, This is my concern about login Currently, in the project the user logs in with it's username and password, it gets an access token only. When the access token expires the user is not authorized anymore. In the task I want to have a refresh token, which will be stored in the cookies. When user loggs in, it gets the Access token and the refresh token. When the access token expires the client side sends a request (with the refresh token in the cookies) for a new "access token". If the refresh token is valid the server responds with a new access token and a new refresh token. - type vfrewq before your praposal then after I'll check your praposal Thanks

    I currently have a website that runs very slow. I need all pages to operate under 3 seconds load time. Currently, average load time is around 4.2 seconds. At times login and registration can take a long time, and the website hangs throughout the users experience. I currently have a react / node.js developer, but they are unable to make any further speed chances. We have sped up the site big time, but still have some room to go. Developer would need to work with my developer. I will not respond to anybody who doesn't write "NGIX" in the beginning of their application.

You will work on my code repository and do regular standups (every day first week, then every other day or as needed). As mentioned, there will most li...
