Add SvelteKit support to `fedify init` by Palcimer · Pull Request #971 · fedify-dev/fedify

Palcimer · 2026-07-27T10:40:27Z

Summary

Fedify already has a SvelteKit integration package and an example app, but fedify init command could not scaffold a SvelteKit project. Added a SvelteKit web framework option to @fedify/init.

closes Add SvelteKit support to fedify init #892

Changes

Added webframeworks/sveltekit.ts which defines the WebFrameworkDescription and scaffolding command for SvelteKit.
Added a template file(hooks.server.ts) that integrates Fedify into a SvelteKit app.
Updated @fedify/init README.md and a tutorial document to include SvelteKit support.
Skipped the deno lookup test for SvelteKit, matching Astro, Nuxt and SolidStart, since Vite can't resolve @fedify/* packages that are only linked through Deno's local workspace links.

Benefits

Users can generate a SvelteKit app using fedify init.

📝 Walkthrough

Walkthrough

fedify init now supports SvelteKit project scaffolding, including package-manager commands, Fedify hook generation, registry wiring, test handling, dependency updates, and documentation.

Changes

SvelteKit init support

Layer / File(s)	Summary
SvelteKit scaffolding and registration `packages/init/src/const.ts`, `packages/init/src/types.ts`, `packages/init/src/webframeworks/`, `packages/init/src/templates/sveltekit/`, `packages/init/src/json/*`	Adds SvelteKit to the framework registry. It defines project creation commands, dependencies, tasks, and a Fedify `hooks.server.ts` integration.
Test and configuration handling `packages/init/src/test/*`	Updates SvelteKit port replacement, records the unsupported Deno remote-package case, and adjusts import typing.
Documentation and release notes `packages/init/README.md`, `docs/tutorial/microblog.md`, `CHANGES.md`	Documents SvelteKit in supported options, the interactive prompt, and the 2.4.0 changelog.

vite does not inject environment variables from .env into process.env, which causes errors during testing using mysql. You can test it with mise test:init -w sveltekit -p pnpm -m mysql -k mysql --no-dry-run. Add dotenvx as a dependency and ensure that if the package manager is not Deno, the task is modified to dotenvx run -- <command>. For example, if dev: "vite dev" is automatically generated, it should be changed to dev: "dotenvx run -- vite dev".

fedify-dev#892

Vite does not inject `.env` variables into `process.env`, so non-Deno SvelteKit projects failed during `mise test:init` runs that need KV/MQ connection settings (e.g. with `mysql`). Add `@dotenvx/dotenvx` as a dev dependency and wrap the `dev`/`build`/`preview` tasks with `dotenvx run --` for every non-Deno package manager. fedify-dev#892 Assisted-by: Claude Code:claude-sonnet-5
