useQueries passing ctx data to splitLink not working
When tRPC is implemented with splitLink using useQueries does not pass cxt parameters to splitLink.
Current implementation:
Implementation of
const trpcClient = trpc.createClient({
links: [
splitLink({
condition(opts: any) {
console.log("OPTS", opts.context.useOnline) // <= NO DATA IF useQueries used
return opts.context.useOnline
},
true: httpBatchLink({
url: "http://localhost:45835/api", // TODO: replace with online URL
headers: async () => {
const token = await getAccessTokenSilently()
return {
authorization: token,
user: JSON.stringify({
name: user?.name,
org: user?.org,
}),
application: activeApp,
}
},
}),
false: httpBatchLink({
url: "http://localhost:45835/api",
headers: async () => {
return {
authorization: "offline",
user: JSON.stringify({
name: "offline",
org: "OFFL",
}),
application: activeApp,
}
},
}),
}),
],
})
const trpcClient = trpc.createClient({
links: [
splitLink({
condition(opts: any) {
console.log("OPTS", opts.context.useOnline) // <= NO DATA IF useQueries used
return opts.context.useOnline
},
true: httpBatchLink({
url: "http://localhost:45835/api", // TODO: replace with online URL
headers: async () => {
const token = await getAccessTokenSilently()
return {
authorization: token,
user: JSON.stringify({
name: user?.name,
org: user?.org,
}),
application: activeApp,
}
},
}),
false: httpBatchLink({
url: "http://localhost:45835/api",
headers: async () => {
return {
authorization: "offline",
user: JSON.stringify({
name: "offline",
org: "OFFL",
}),
application: activeApp,
}
},
}),
}),
],
})
useQueries usage
const data = trpc.useQueries((t) =>
machines.map((machine) =>
t.heatmap(
{
machine,
kpis: ["lossTime"],
},
{ trpc: getMachineMode(machine) } // <= This function returns { ctx: { useOnline: true/false } }
)
)
)
const data = trpc.useQueries((t) =>
machines.map((machine) =>
t.heatmap(
{
machine,
kpis: ["lossTime"],
},
{ trpc: getMachineMode(machine) } // <= This function returns { ctx: { useOnline: true/false } }
)
)
)

Note: This way of passing data to splitLink works on
useQueryIf you think it's a bug, open an issue with a small reproduction 🙏
