is there a better way to do this?

let query;
let params;
switch (getWhat) {
case "posts":
query = api.user.userPosts;
params = { user: uid, what: "posts", cursor: at };
break;
case "likes":
query = api.user.userPosts;
params = { user: uid, what: "likes", cursor: at };
break;
case "following":
query = api.user.followedPosts;
}

//@ts-ignore
const { data, isPlaceholderData } = query.useQuery(params, {
//@ts-ignore
placeholderData: (prevRes) => prevRes ?? initPosts,
});
let query;
let params;
switch (getWhat) {
case "posts":
query = api.user.userPosts;
params = { user: uid, what: "posts", cursor: at };
break;
case "likes":
query = api.user.userPosts;
params = { user: uid, what: "likes", cursor: at };
break;
case "following":
query = api.user.followedPosts;
}

//@ts-ignore
const { data, isPlaceholderData } = query.useQuery(params, {
//@ts-ignore
placeholderData: (prevRes) => prevRes ?? initPosts,
});
so i have a component that renders a post list according to varying api calls however, this requires the two ts-ignore at the bottom. is there a way to tell ts that the two api calls result in the exact same type?

your implementation is against the laws of hooks. Hooks should not be called conditionally. Instead, you can make use of the enabled option of react query. I think this is the good way of doing what you want.
const { data: posts, isPlaceholderData: isPlaceholderPosts } = api.user.userPosts.useQuery({
user: uid, what: getWhat as 'posts' | 'likes', cursor: at
}, {
enabled: getWhat === 'posts' || getWhat === 'likes',
placeholderData: (prevRes) => prevRest ?? initPosts
})

const { data: following, isPlaceholderData: isPlaceholderFollowing } = api.user.followedPosts.useQuery(undefined, {
enabled: getWhat === 'following',
placeholderData: (prevRes) => prevRest ?? initPosts
})
const { data: posts, isPlaceholderData: isPlaceholderPosts } = api.user.userPosts.useQuery({
user: uid, what: getWhat as 'posts' | 'likes', cursor: at
}, {
enabled: getWhat === 'posts' || getWhat === 'likes',
placeholderData: (prevRes) => prevRest ?? initPosts
})

const { data: following, isPlaceholderData: isPlaceholderFollowing } = api.user.followedPosts.useQuery(undefined, {
enabled: getWhat === 'following',
placeholderData: (prevRes) => prevRest ?? initPosts
})
If you want to use only one variable for any of the data you can do this:
const data = posts || following
const isPlaceholderData = isPlaceholderPosts || isPlaceholderFollowing
const data = posts || following
const isPlaceholderData = isPlaceholderPosts || isPlaceholderFollowing
This issue is more of react-query related rather than trpc.
