Unified routing and caching logic for applications utilizing a content delivery network
Disclosed are systems and methods for providing unified routing and caching logic for applications utilizing a CDN. First, the system maintains access to one or more edge servers for a CDN, with the one or more edge servers being configured to execute edge logic. The system receives code for an application in a specified application framework, with the code and/or application framework including a unified set of routing and caching logic for dynamic data to be applied to a number of caches, and with the unified set of routing and caching logic being derived from a centralized definition. For each of the caches, the system first analyzes the set of routing and caching logic to determine a subset of the routing and caching logic to be executed by the cache, and then atomically sends the determined subset of the routing and caching logic to the cache.

(1) the one or more caches, of the plurality of caches of the web application, to which at least some of the set of routing and caching logic apply, and
(2) for each cache of the one or more caches, a subset of the routing and caching logic applicable to the respective cache; and
for each cache of the one or more caches, triggering configuration of the respective cache with the subset of the routing and caching logic identified in the analyzing as applicable to the respective cache, wherein the triggering configuration for each cache of the plurality of caches comprises sending the subset of the routing and caching logic to the respective cache.
2. The method of claim 1 , wherein the plurality of caches comprises at least one of: a browser cache, a service worker cache, or one or more CDN caches.
3. The method of claim 1 , wherein the routing and caching logic comprises one or more of: cache expiration times, stale-while-revalidate time, cache key computation logic, associated application version, private and public cache behaviors, browser and edge cache behaviors, or prefetch behaviors.
4. The method of claim 1 , further comprising:
in response to a request in the web application, directing the request to a version of edge logic corresponding to a version of the code of the web application.
5. The method of claim 4 , further comprising:
receiving a cache policy associated with at least one of the plurality of caches; and
atomically binding the cache policy and the code for the web application such that the cache policy executes only in conjunction with the version of the code of the web application.
6. The method of claim 1 , further comprising:
selecting the web application from a plurality of application versions of the web application, wherein each application version comprises a different version of the code of the web application and of the routing and caching logic for each of the plurality of caches based on a past deployment of the web application.
7. The method of claim 1 , wherein the web application is executed such that dynamic web pages and/or API data are pre-fetched and served from one or more edge servers according to the set of routing and caching logic.
8. The method of claim 1 , further comprising:
providing the code of the web application and the routing and caching logic for each of the plurality of caches to local storage of a client device,
wherein the code of the web application and the routing and caching logic for each of the plurality of caches is processed and/or executed locally at the client device when the CDN is not accessible by the client device.
9. The method of claim 1 , wherein the set of routing and caching logic for the web application is a unified set of routing and caching logic for the plurality of caches of the web application.
10. The method of claim 1 , wherein, for each cache of the one or more caches, sending the subset of the routing and caching logic to the cache comprises, for each cache of the one or more caches, atomically sending the subset of the routing and caching logic to the respective cache.
11. At least one non-transitory computer-readable medium containing instructions that, when executed by at least one processor, cause the at least one processor to carry out a method of configuring one or more caches of a web application to be used with a content delivery network (CDN), the web application being in an application framework and comprising a plurality of caches, the method comprising:
analyzing code for the web application in the application framework to identify, from a set of routing and caching logic for the web application,
(1) the one or more caches, of the plurality of caches of the web application, to which at least some of the set of routing and caching logic apply, and
(2) for each cache of the one or more caches, a subset of the routing and caching logic applicable to the respective cache; and
for each cache of the one or more caches, triggering configuration of the respective cache with the subset of the routing and caching logic identified in the analyzing as applicable to the respective cache, wherein the triggering configuration for each cache of the plurality of caches comprises sending the subset of the routing and caching logic to the respective cache.
12. The at least one non-transitory computer-readable medium of claim 11 , wherein the plurality of caches comprises at least one of: a browser cache, a service worker cache, or one or more CDN caches.
13. The at least one non-transitory computer-readable medium of claim 11 , wherein the routing and caching logic comprises one or more of: cache expiration times, stale-while-revalidate time, cache key computation logic, associated application version, private and public cache behaviors, browser and edge cache behaviors, or prefetch behaviors.
14. The at least one non-transitory computer-readable medium of claim 11 , wherein the method further comprises: in response to a request in the web application, directing the request to a version of edge logic corresponding to a version of the code of the web application.
15. The at least one non-transitory computer-readable medium of claim 14 , wherein the method further comprises:
receiving a cache policy associated with at least one of the plurality of caches; and
atomically binding the cache policy and the code for the web application such that the cache policy executes only in conjunction with the version of the code of the web application.
16. The at least one non-transitory computer-readable medium of claim 11 , wherein the method further comprises:
selecting the web application from a plurality of application versions of the web application, wherein each application version comprises a different version of the code of the web application and of the routing and caching logic for each of the plurality of caches based on a past deployment of the web application.
17. The at least one non-transitory computer-readable medium of claim 11 , wherein the web application is executed such that dynamic web pages and/or API data are pre-fetched and served from one or more edge servers according to the set of routing and caching logic.
18. The at least one non-transitory computer-readable medium of claim 11 , wherein the method further comprises:
providing the code of the web application and the routing and caching logic for each of the plurality of caches to local storage of a client device,
wherein the code of the web application and the routing and caching logic for each of the plurality of caches is processed and/or executed locally at the client device when the CDN is not accessible by the client device.
19. A communication system comprising:
one or more processors; and
