Vani SSR and Hydration

Instructions for rendering on the server and hydrating on the client with explicit activation.

When to Use

Use this when a project needs SSR or SSG, or when hydration must be selective.

Steps

1. Render on the server with renderToString(App()) (arrays also work).
2. On the client, call hydrateToDOM(App(), root) (arrays also work) to bind handles to anchors.
3. Activate interactivity by calling handle.update() on the handles you want to run.
4. For selective hydration, update only specific handles (e.g., header) and leave others inert.

Arguments

• rootId - DOM id that contains server HTML (defaults to app)
• activateAll - whether to update all handles immediately (defaults to true)
• selectiveRefs - list of component refs to activate (defaults to [])

Examples

Example 1 usage pattern:

SSR a page, hydrate on the client, then call handle.update() for all handles.

Example 2 usage pattern:

Hydrate a page but activate only the header using a ComponentRef.

Output

Example output:

Created: server/render.ts
Updated: client/entry.ts
Notes: Hydration binds to anchors; update() activates UI.

Present Results to User

Summarize the SSR/hydration flow, note which handles are activated, and list file changes.

Vani SSR and Hydration Command

When to use

Use this skill when implementing SSR, SSG, hydration, or client-only islands.

Instructions

Follow these steps:

1. For SSR/SSG, render with renderToString() on the server (single or array).
2. Bind on the client with hydrateToDOM() (single or array); do not expect it to render.
3. Activate UI by calling handle.update() on chosen handles.
4. Use clientOnly: true for islands that should skip SSR.
5. Keep hydration order identical to the server render order.

Output expectations

• Use only @vanijs/vani or other public packages.
• Do not assume hydration runs effects before handle.update().
• If $ARGUMENTS is provided, pick the correct render/hydration strategy.
