statikapi — Static API generator (CLI)

Build a folder of JSON endpoints from simple files, then preview them in a lightweight UI.

Requires Node 18+.

Install

Use without installing (recommended):

npx statikapi --help

Or add to a project
pnpm add -D statikapi
# npm i -D statikapi
# yarn add -D statikapi

Commands

statikapi <command> [options]

Commands:
  build       Build static JSON endpoints
  dev         Watch & rebuild on changes

Global:
  -h, --help      Show help
  -v, --version   Show version

##Quick start

# 1) Create a folder with API sources

mkdir src-api
echo "export default { hello: 'world' }" > src-api/index.js

# 2) Build

npx statikapi build --pretty

# 3) Preview (opens http://127.0.0.1:8788/_ui)

npx statikapi preview

Project layout

• src-api/: your source files (default; configurable)
• api-out/: generated JSON, one folder per route (default)

Examples of file → route mapping:

File Route Output file src-api/index.js / api-out/index.json src-api/blog/archive.js /blog/archive api-out/blog/archive/index.json src-api/users/[id].js /users/:id dynamic (see below) src-api/docs/[...slug].js /docs/*slug catch-all (see below)

Dynamic routes

For src-api/users/[id].js, export a paths() function that returns the concrete IDs to prebuild:

// src-api/users/[id].js
export async function paths() {
return ['1', '2', '3']; // builds /users/1, /users/2, /users/3
}

export async function data({ params }) {
return { id: params.id };
}

Catch-all works similarly:

// src-api/docs/[...slug].js
export async function paths() {
return [['a', 'b'], ['guide']]; // → /docs/a/b and /docs/guide
}
export async function data({ params }) {
return { slug: params.slug, path: params.slug.join('/') };
}

Producing data

Each module can export either:

• export async function data(ctx) { ... } → its return value is serialized, or
• export default <value|function> → if a function, it’s called and awaited.

Returned data must be JSON-serializable (plain objects/arrays, finite numbers, no functions, etc.).

Config

You can optionally add statikapi.config.js in your project root:

export default {
srcDir: 'src-api',
outDir: 'api-out',
};

You can override via flags: --srcDir <dir>, --outDir <dir>.

Flags (per command)

build

• --pretty (or --minify=false) — pretty-print JSON.
• --srcDir, --outDir — override config paths.

dev

• Rebuilds on changes, updates the preview UI via SSE.
• --previewHost, --previewPort — where to notify the preview server.
• --srcDir, --outDir — override config paths.
• --host (default 127.0.0.1)
• --port (default 8788)
• --open — try to open the browser
• UI source:
  • --uiDir <path> — serve a built UI from this directory
  • Otherwise, uses the embedded UI bundled with the CLI
  • If missing, proxies to a dev UI at http://127.0.0.1:5173 (override with --uiDevHost, --uiDevPort)

Examples

There are two example projects in this repo under example/:

# from repo root

pnpm -C example/basic dev
pnpm -C example/basic build

pnpm -C example/dynamic dev
pnpm -C example/dynamic build

pnpm -C example/showcase dev
pnpm -C example/showcase build

Troubleshooting

• Dynamic routes not emitted: make sure the file exports a valid paths() function returning strings (or arrays of strings for catch-all).
