One method includes operations for receiving at a server a request for an update to the UI of a client device, and for determining, by an orchestrator at the server, modules associated with the request, each module being presented on the UI. Further, the method includes operations for invoking domain services based on the determined modules (each domain service returning respective domain service data), and for synthesizing the domain service data to generate module data for each module. The synthesizing includes selecting from the domain service data and combining the selected domain service data to generate the module data. The module data is transmitted to the client device for all the modules, the module data being processable by the client device to update modules of the UI. ## Claims ### Claim 1 A method comprising: receiving at a server, from a client device, a request for an update to a user interface (UI) of the client device, the request being part of a single call to one orchestrator for multiple domain services, the one orchestrator at the server; determining, based on the request, by the one orchestrator, one or more modules of the UI; invoking, by the orchestrator, one or more domain services of the multiple domain services based on the determined modules, each domain service of the one or more domain services returning respective domain service data; synthesizing the domain service data returned by the one or more domain services to generate module data for each module, the synthesizing including selecting selected domain service data from the domain service data and combining the selected domain service data to generate the module data; and transmitting to the client device the module data for updating the modules of the UI. ### Claim 2 (depends on 1) The method as recited in claim 1, wherein the determining of the one or more modules further includes: selecting an entry in a module selection table based on the request, wherein the module selection table includes a plurality of fields that include a marketplace field, a device type field, and a modules field; and selecting the modules identified in the modules field of the selected entry. ### Claim 3 (depends on 2) The method as recited in claim 2, wherein the plurality of fields in the module selection table further include a view field, a user-segment field, and an experimentation field. ### Claim 4 (depends on 2) The method as recited in claim 2, wherein the determining the one or more modules further includes: detecting a device type and a device-operating-system type based on the request, wherein the selecting the entry of the module selection table is based on the detected device type and device-operating-system type. ### Claim 5 (depends on 1) The method as recited in claim 1, further including: detecting an error returned by one of the domain services; and performing error recovery at the server based on the detected error. ### Claim 6 (depends on 1) The method as recited in claim 1, wherein the one or more domain services include one or more of a user-information service, a marketplace service, a seller information service, a search service, and a messaging service. ### Claim 7 (depends on 1) The method as recited in claim 1, wherein the synthesizing the domain service data further includes: identifying data from the domain service data needed for generating the module data; and extracting the identified data, wherein domain service data unnecessary for the generating the module data is not transmitted to the client device. ### Claim 8 (depends on 1) The method as recited in claim 1, wherein a first module is presentable on two or more client device types, wherein the synthesizing the domain service data includes creating the module data for the first module based on the two or more client device types. ### Claim 9 (depends on 1) The method as recited in claim 1, wherein a second module is configured to present on the UI of the client device an item for sale, wherein the module data for the second module includes an image of the item for sale, a price of the item for sale, and a description of the item for sale. ### Claim 10 (depends on 1) The method as recited in claim 1, wherein the server further includes an experimentation component, the method further including: sending, from the experimentation component at the server to the client device, experimentation data identifying an experiment for the client device, wherein the experimentation data is transmitted to the client device to test a service feature. ### Claim 11 A server comprising: a communications interface for receiving a request for an update to a user interface (UI) of a client device; a memory including instructions of an orchestrator program; and one or more computer processors, wherein the instructions, when executed by the one or more computer processors, cause the one or more computer processors to perform operations comprising: determining one or more modules based on the request and a module selection table stored in the memory, each module being part of the UI;
