How to modify Liveblocks Storage from the server

In realtime applications, Liveblocks Storage is generally modified from the browser with useMutation or through conflict-free data methods. However, it can also be useful to modify your realtime storage from server-side Node.js too.

What we’re doing

In this guide, we’ll demonstrate how to easily modify storage from the server. We’ll do this using @liveblocks/node.

Start modifying storage

We can now start modifying storage from the server!

// Creating a node client (centrally)const liveblocks = new Liveblocks({ secret: "sk_prod_xxxx…xxxxxxsk_prod_xxxxxxxxxxxxxxxxxxxxxxxx",});
export async function POST() { console.log("Updating storage");
 // Mutate storage await liveblocks.mutateStorage( "my-room",
 ({ root }) => { root.get("list").push("item3"); } );
 console.log("Storage update complete!");}
