ftd gives a way for its platform,
fastn, to define some functions known as
processors. These functions, then, can be used in the
ftd, and their
execution is handled by the platform.
fastn contains the following processors:
fastn/processorwhich must be imported to use any of these processors.
fastnin static site mode, then how the page looked when
fastn buildwas called will be shown to everyone. But if you are using dynamic mode then this page would be regenerated on every page load.
$processor$key is used.
-- import: fastn/processors as pr -- person list people: $processor$: pr.package-query db: db.sqlite SELECT * FROM user;
As you see
$processor$ key was used when defining the variable called
$processor$ is used, the rest of the section is in determined
bu the specific processor used. Like in this case the processor
pr.package-query expects a key named
db, which refers to the database file,
and the body of the section is the SQL query to execute against the database.
A processor must be used on a variable or a list with matching type as the
output of the processor. In this case we are using
SELECT * FROM user; so the
columns of the
user table must match the fields of the record
data will be ignored, but all required data must be passed for processor to
fastnis planning to use wasmtime to let anyone write their own custom processors, which will allow much more functionalities.
