Output
Outputs are seldom integral to an app but can be useful in specific situations.
An output is invoked after a query is completed. The output of the query along with the input and context are then passed to the output callback.
Example
fetchFruit: tsdl
.input(z.literal("banana"))
.use(() => "orange")
.query(() => "apple")
.output((res) => {
res.input; // "banana"
res.ctx; // "orange"
res.output; // "potato"
})
.output(console.log),Type
type Output = <TCtx, TInput, TOutput, TReturn>(res: {
ctx: TCtx;
input: TInput;
output: TOutput;
} => TReturn);The return value of the output is ignored
Outputs can throw errors and thereby modify the response. If one output throws, no further outputs will be invoked.
⚠️
All outputs will need to be resolved before a request is fulfilled, the output callbacks are run invoked parallel.
