I am trying to create an infinite scroll, list using
solid-infinite-scroll and solid-trpc (solid-start), there is little to no documentation on solid-trpcitself, as it uses different methods from the original, but using the original as the base
The following code is what im doing, this returns undefined and keeps loading the same data:
const query = trpc.eep.infiniteFeed.useInfiniteQuery(
() => ({}),
() => ({
getNextPageParam: (lastPage) => {
return () => ({
cursor: lastPage.nextCursor,
});
},
initialPageParam: () => ({}),
})
);
const query = trpc.eep.infiniteFeed.useInfiniteQuery(
() => ({}),
() => ({
getNextPageParam: (lastPage) => {
return () => ({
cursor: lastPage.nextCursor,
});
},
initialPageParam: () => ({}),
})
);
//...
infiniteFeed: procedure
.input(
z.object({
onlyFollowing: z.boolean().optional(),
limit: z.number().optional(),
cursor: z
.object({
id: z.string(),
createdAt: z.date(),
})
.optional(),
})
)
.query(
async ({
input: { limit = 10, onlyFollowing = false, cursor },
ctx,
}) => {
const currentUserId = ctx.session?.user?.id;
console.log('HERE', cursor);
let whereClause = undefined;
if (onlyFollowing) {
whereClause = {
user: {
followers: {
some: { id: currentUserId },
},
},
};
}
const eeps = await getInfiniteEeps({
whereClause,
limit,
cursor,
currentUserId,
ctx,
});
return eeps;
}
),
