Presolve documentation · 0.2.0-beta.26

Learn the whole system.

Presolve is a compiler-founded, static-first framework for TypeScript and JSX. These guides connect the authoring model to the exact HTML, browser plans, resume records, diagnostics, and deployment inventory it produces.

Start here

Build an interactive route in minutes.

Create a project, learn the canonical application files, and watch one explicit action update compiler-owned state.

Follow the quickstart

pnpm create presolve@0.2.0-beta.26 my-appcd my-apppnpm dev

Learn by goal

Start a project

Install the beta, understand the scaffold, run locally, and make the first production build.

Quickstart →02

Own the application

Learn why document, shell, route, CSS, public, server, and generated files have distinct homes.

Structure guide →03

Build the interface

Define components, inputs, nested ownership, conditions, keyed lists, and teardown.

Component guide →04

Add behavior

Use state, actions, pure computed getters, effects, event parameters, and cleanup.

Reactivity guide →05

Style the publication

Use global CSS, Tailwind, public assets, and Vite without creating a second semantic authority.

Styling guide →06

Compose features

Project default and named slots, understand caller ownership, and use Context deliberately.

Composition guide →07

Handle application data

Model forms, validation, submission state, resource lifecycles, and endpoint boundaries.

Data guide →08

Prove and ship

Check diagnostics, inspect generated products, verify behavior, and deploy the full inventory.

Production guide →

Understand Presolve

Compiler ownership

Why the compiler—not a browser renderer—owns semantics, identity, order, and products.

Resumability

How a compatible snapshot restores exact state and bindings without replaying the tree.

Language boundary

Which TypeScript and JSX forms the beta admits, and why type-correct code may still fail closed.

Support matrix

What is production-proven in this beta, what is compatibility-only, and what is not a promise.

Know the boundary

Presolve 0.2 beta is not a generic SSR or arbitrary server runtime. Its Node host executes only compiler-proven loaders and Form-bound actions. Arbitrary TypeScript and package internals are not silently accepted; unsupported semantics produce a compiler diagnostic instead of falling back to a large client runtime.
