SystemService::CommonSys

struct SystemService::CommonSys {
    const psibase::AccountNumber service; // "common-sys"

    serveSys(...); // This is a standard action that allows common-sys to serve http requests.
    storeSys(...); // This is a standard action that allows files to be stored in common-sys
};

Services that contains the common files and libraries used by apps on psibase.

SystemService::CommonSys::serveSys

std::optional<psibase::HttpReply> SystemService::CommonSys::serveSys(
    psibase::HttpRequest request
);

This is a standard action that allows common-sys to serve http requests..

common-sys responds to GET requests:

/applet/APPLET_NAME
/common/thisservice
/common/rootdomain
/common/tapos/head and to POST requests:
/common/pack/Transaction
/common/pack/SignedTransaction

When responding to the /applet/APPLET_NAME GET request, then common-sys returns the file stored at the root index. That file reads the URL bar, detects that an applet is being loaded, and request the applet to load inside an iframe.

Additionally, common-sys will serve content at any path stored using storeSys

SystemService::CommonSys::storeSys

void SystemService::CommonSys::storeSys(
    std::string       path,
    std::string       contentType,
    std::vector<char> content
);

This is a standard action that allows files to be stored in common-sys.

These files can later be retrieved using serveSys.
