Get Building

create-t3svelte-app is completely modular. Choose the components you need!

✅ Elegant full-stack framework powered by SvelteKit
✅ Static typing support with TypeScript
✅ End-to-end typesafe APIs with tRPC
✅ Enjoyable database interaction with Prisma
✅ Efficient styling with Tailwind CSS

``bash
npx create-t3svelte-app@latest
`

If you choose not to init DB on first build, you can initialize prisma db at any time by editing the DATABASE_URL in .env and then running npx prisma db pull and npx prisma generate. You can read more about Prisma on their docs.

Available Templates

A simple CLI with highly opinionated, out-of-the-box ready SvelteKit/tRPC/Prisma/Tailwind application. CLI options include 'Standard' and 'Custom' (modular build). Just run and start building.

- SvelteKit
- TypeScript
- tRPC - preconfigured with example API call in +page.svelte
- Tailwind CSS - preconfigured with eslint/prettier & 'tailwind prettier plugin' integration
- Prisma ORM - CLI option to initialize DB on run - no need to run prisma db pull or prisma db generate

Contributing

See a bug? Want to help? Easiest way is to clone the main repo and run npm link in the cloned directory. You can code and then run create-t3svelte-app in any directory.

`bash
git clone https://github.com/zach-hopkins/create-t3svelte-app
cd create-t3svelte-app
npm i
npm link
mkdir test-project
cd test-project
create-t3svelte-app
`

Run npm unlink create-t3svelte-app to undo.

Caveats & Addendums

If you need to use the tRPC client in SvelteKit's load() function for SSR, make sure to initialize it like so:

`ts
// $lib/trpcClient.ts

import { browser } from '$app/env';
import type { Router } from '$lib/trpcServer';
import * as trpc from '@trpc/client';
import type { LoadEvent } from "@sveltejs/kit";

const url = browser ? '/trpc' : 'http://localhost:3000/trpc';
export default (loadFetch?: LoadEvent['fetch']) =>
trpc.createTRPCClient({
url: loadFetch ? '/trpc' : url,
transformer: trpcTransformer,
...(loadFetch && { fetch: loadFetch as typeof fetch })
});

`

Then use it like so:

`ts
// src/routes/+authors.svelte

import trpcClient from '$lib/trpcClient';
import type { Load } from '@sveltejs/kit';

export const load: Load = async ({ fetch }) => { // 👈 make sure to pass in this fetch, not the global fetch
const authors = await trpcClient(fetch).query('authors:browse', {
genre: 'fantasy',
});
return { props: { authors } };
};
`

Your server responses must satisfy some criteria in order for them to be cached on Vercel's Edge Network. tRPC's responseMeta() comes in handy here since you can initialize your handle in src/hooks.server.ts like so:

`ts
// src/hooks.server.ts

import { router } from '$lib/trpcServer';
import { createTRPCHandle } from 'trpc-sveltekit';

export const handle = async ({ event, resolve }) => {
const response = await createTRPCHandle({
url: '/trpc',
event,
resolve,
responseMeta({ type, errors }) {
if (type === 'query' && errors.length === 0) {
const ONE_DAY_IN_SECONDS = 60 60 24;
return {
headers: {
'cache-control': s-maxage=1, stale-while-revalidate=${ONE_DAY_IN_SECONDS}
}
};
}
return {};
}
});

return response;
};
``
