A proof of concept of a tree shakable Zod alternative. This library aims to have a 1:1 Zod compatible API, but with fine grain control over the final bundle size. This was done by a combination of Proxies and type-level programming.

🤓 You can read the blog post to learn how it works.
// 1. import `initCorrettore` and features (validator) you want to use import { initCorrettore, string, email, min, object } from "correttore"; // 0.54 kB // 2. init the entrypoint variable `c`. It corresponds to Zod's `z`. export const c = initCorrettore([string, email, min, object]); // 3. create schemas. Autocompletion will only show methods passed to `initCorrettore`. // the `object` method is always available const loginSchema = c.object({ email: c.string().email(), password: c.string().min(5), }); // 4. Infer type from schema: import type { Infer } from "correttore"; type LoginSchema = Infer<typeof loginSchema>; // ^? { // email: string; // password: string; // } // 5. Parse unknown data const parsed = loginSchema.parse({ email: "hello@test.com", password: "password123", }); // this will throw loginSchema.parse({ email: "hello@test.com", // missing field });
Note: This library is not production ready, I implemented only a handful of parsers as a PoC. If you're interested in this project, check out the contributing section.
# choose your package manager
pnpm add correttore
yarn add correttore
npm install correttoreimport { z } from "zod"; // 12.8 kB const LoginSchema = z.object({ email: z.string().email(), password: z.string().min(8), }); // Throws error LoginSchema.parse({ email: "", password: "" }); // Returns data as { email: string; password: string } LoginSchema.parse({ email: "jane@example.com", password: "12345678" });
import { email, min, initCorrettore, string, object } from "correttore"; // 0.54 kB export const c = initCorrettore([string, email, min, object]); const LoginSchema = c.object({ email: c.string().email(), password: c.string().min(8), }); // Throws error LoginSchema.parse({ email: "", password: "" }); // Returns data as { email: string; password: string } LoginSchema.parse({ email: "jane@example.com", password: "12345678" });
If you're interested in helping to bring this project to a production ready state, feel free to open a PR with changes that will bring it closer to a 1:1 Zod compatible API.
