## Minimize Serialization at RSC Boundaries
|
|
|
|
The React Server/Client boundary serializes all object properties into strings and embeds them in the HTML response and subsequent RSC requests. This serialized data directly impacts page weight and load time, so **size matters a lot**. Only pass fields that the client actually uses.
|
|
|
|
**Incorrect (serializes all 50 fields):**
|
|
|
|
```tsx
|
|
async function Page() {
|
|
const user = await fetchUser(); // 50 fields
|
|
return <Profile user={user} />;
|
|
}
|
|
|
|
("use client");
|
|
function Profile({ user }: { user: User }) {
|
|
return <div>{user.name}</div>; // uses 1 field
|
|
}
|
|
```
|
|
|
|
**Correct (serializes only 1 field):**
|
|
|
|
```tsx
|
|
async function Page() {
|
|
const user = await fetchUser();
|
|
return <Profile name={user.name} />;
|
|
}
|
|
|
|
("use client");
|
|
function Profile({ name }: { name: string }) {
|
|
return <div>{name}</div>;
|
|
}
|
|
```
