Change it in one place, update it in all. A simple and powerful way. The best way to save money and time if you have elements that change often and use them in several sites.
How many times have you brought functionality from one project to another? Now you can save those functionalities in a single site ready to include them easily where you need them. Try using Web Components in the cloud.
Create basic pieces (css, js, html), common pieces (header, footer, menu, ...) and page pieces. Include in each other. Now your site is dynamic, modular and maintainable. Manage each element from wpiece as if it were a cms.
Generates content for third parties. Modify it without having to do anything other than modify your piece.
Changes analytic services, advertising, geolocation or any widget ... but without spending money or development time. Do not touch your code.
If you have third-party elements, or browsers change, update the piece but not your application.
If a page has several areas. If an area is a piece and each piece is managed by an author. Do something great with all of them and everyone can manage their part without intermediaries.
Develops useful functionality. Have you tried the Web Components ? Decide who can use it (by IP, domain or user wpiece). Create different versions for different clients. Get usage reports. Sell it.
If you need a dynamic piece. If the url that generat your content may change in the future. If you do not want that address known. Wpiece encapsulates you.
Create a single access point to your system that allows wpiece to read the information. Manage access to that information from the platform without having to open more doors to your system.
Publisher: Put areas of your site available to customers. Control the use of the space provided (number of expositions).
Advertiser: create your piece with the ad and modify it whenever you need it.
Generate versions and program them over time. Advance your work.
wpiece as a private cloud platform. Duplication and / or adaptation of the application to the needs of the client. Custom development of functionalities.
