openpkg-ts
TypeScript API extraction and documentation toolkit. Extract complete API specifications from source code, then generate docs for any framework.
Deep dive: Read content/new-standard-who-dis/index.mdx for Standard JSON Schema and runtime introspection details.
Why
- Zero manual docs — Extract everything from TypeScript source
- Framework agnostic — Fumadocs, Docusaurus, Mintlify, or custom
- Schema library support — Zod, Valibot, ArkType, TypeBox (requires
--runtimeflag) - Version tracking — Diff specs and get semver recommendations
Install
npm install -g @openpkg-ts/cli
# or use directly
npx @openpkg-ts/cli <command>
CLI Commands
list — List exports from entry point
openpkg list src/index.ts
# Output: JSON array of { name, kind, file, line, description }
get — Get detailed spec for single export
openpkg get src/index.ts createClient
# Output: JSON with { export, types }
snapshot — Generate full spec
openpkg snapshot src/index.ts -o openpkg.json # Write to file
openpkg snapshot src/index.ts -o - # Stdout (pipeable)
openpkg snapshot src/index.ts --runtime # Enable Zod/Valibot extraction
openpkg snapshot src/index.ts --only "use*,create*" # Filter exports
openpkg snapshot src/index.ts --ignore "*Internal" # Exclude exports
openpkg snapshot src/index.ts --max-depth 4 # Type depth limit
openpkg snapshot src/index.ts --verify # Exit 1 if any fail
| Flag | Description |
|---|---|
-o, --output <file> |
Output file (default: openpkg.json, - for stdout) |
--max-depth <n> |
Max type depth (default: 4) |
--skip-resolve |
Skip external type resolution |
--runtime |
Enable Standard Schema runtime extraction (Zod, Valibot) |
--only <exports> |
Filter exports (comma-separated, wildcards) |
--ignore <exports> |
Ignore exports (comma-separated, wildcards) |
--verify |
Exit 1 if any exports fail |
docs — Generate documentation from spec
openpkg docs openpkg.json -o api.md # Markdown (default)
openpkg docs openpkg.json -f html -o api.html # HTML
openpkg docs openpkg.json -f json # JSON (simplified)
openpkg docs openpkg.json --split -o docs/api/ # One file per export
openpkg snapshot src/index.ts -o - | openpkg docs - -f md # Pipeline
diff — Compare specs for breaking changes
openpkg diff old.json new.json
openpkg diff old.json new.json --summary
# Output: breaking, added, removed, changed, docsOnly, summary.semverBump
Static vs Runtime Extraction
CRITICAL: Static analysis misses runtime constraints from schema libraries.
// Source: z.string().email().min(3)
Static only (no --runtime):
{ "type": "string" }
With --runtime:
{ "type": "string", "format": "email", "minLength": 3 }
The --runtime flag:
- Detects TypeScript runtimes (bun, tsx, Node 22+)
- Executes entry file
- Finds Standard JSON Schema exports (
schema['~standard'].jsonSchema) - Merges runtime schemas with static analysis
Always use --runtime when documenting packages with Zod, Valibot, ArkType, or TypeBox.
How It Works
TypeScript Source → [snapshot] → OpenPkg Spec (JSON) → [docs] → Markdown/HTML/JSON
The spec is the intermediate format—validate it, diff it, or feed it to any renderer.
Packages
| Package | Description |
|---|---|
| @openpkg-ts/cli | CLI: list, get, snapshot, docs, diff |
| @openpkg-ts/sdk | Programmatic SDK for extraction, rendering, querying |
| @openpkg-ts/spec | Spec types, validation, normalization, diffing, semver |
| @openpkg-ts/react | React components (headless + styled with Tailwind v4) |
| @openpkg-ts/ui | Low-level UI primitives (CodeHike, Radix) |
| @openpkg-ts/adapters | Framework adapters (Fumadocs) |
SDK Primitives
import { listExports, getExport, extractSpec, diffSpecs, createDocs } from '@openpkg-ts/sdk';
// List exports
const { exports } = await listExports({ entryFile: './src/index.ts' });
// Get single export
const { export: spec, types } = await getExport({ entryFile: './src/index.ts', exportName: 'myFunc' });
// Extract full spec
const { spec, diagnostics } = await extractSpec({
entryFile: './src/index.ts',
maxTypeDepth: 4,
only: ['use*'],
ignore: ['*Internal'],
});
// Generate docs
const docs = createDocs(spec);
const markdown = docs.toMarkdown();
const html = docs.toHTML();
Spec Utilities
import { validateSpec, normalize, diffSpec, recommendSemverBump } from '@openpkg-ts/spec';
validateSpec(spec); // Returns { ok, errors? }
const normalized = normalize(spec); // Consistent structure
const diff = diffSpec(old, new); // Compare specs
const { bump, reason } = recommendSemverBump(diff); // 'major' | 'minor' | 'patch'
React Components
// Styled (Tailwind v4)
import { FullAPIReferencePage, FunctionPage, ClassPage } from '@openpkg-ts/react/styled';
// Headless (unstyled)
import { CollapsibleMethod, ParamTable, Signature } from '@openpkg-ts/react';
Fumadocs Adapter
import { loader } from 'fumadocs-core/source';
import { openpkgSource, openpkgPlugin } from '@openpkg-ts/adapters/fumadocs';
export const apiSource = loader({
baseUrl: '/docs/api',
source: openpkgSource({ spec }),
plugins: [openpkgPlugin()],
});
Use Cases
- Generate API documentation from TypeScript
- Detect breaking changes between versions
- Build custom doc sites with React components

Install
bun add -g @secondlayer/cli
CLI Commands
# Generate from local .clar files
secondlayer generate ./contracts/token.clar -o ./src/generated.ts
# Generate from deployed contracts (network inferred from address)
secondlayer generate SP3K8BC0PPEVCV7NZ6QSRWPQ2JE9E5B6N3PA0KBR9.alex-vault -o ./src/generated.ts
# Glob patterns
secondlayer generate "./contracts/*.clar" -o ./src/generated.ts
# With config file
secondlayer init # creates secondlayer.config.ts
secondlayer generate
Config File
// secondlayer.config.ts
import { defineConfig } from '@secondlayer/cli'
import { clarinet, actions, react } from '@secondlayer/cli/plugins'
export default defineConfig({
out: 'src/generated.ts',
plugins: [
clarinet(), // parse local Clarinet project
actions(), // add read/write helpers
react(), // generate React hooks
],
})
Generated Usage
Contract Calls
import { token } from './generated/contracts'
import { makeContractCall, fetchCallReadOnlyFunction } from '@stacks/transactions'
// Works with @stacks/transactions directly
await makeContractCall({
...token.transfer({ amount: 100n, recipient: "SP..." }),
network: 'mainnet',
})
await fetchCallReadOnlyFunction({
...token.getBalance({ account: "SP..." }),
network: 'mainnet',
})
Read/Write Helpers (requires actions plugin)
// Read-only
const balance = await token.read.getBalance({ account: "SP..." })
// Write (uses STX_SENDER_KEY env var)
await token.write.transfer({ amount: 100n, recipient: "SP..." })
// Or pass senderKey explicitly
await token.write.transfer({ amount: 100n, recipient: "SP..." }, "<sender-key>")
Contract State
// Maps
const balance = await token.maps.balances.get("SP...")
// Variables
const supply = await token.vars.totalSupply.get()
// Constants
const max = await token.constants.maxSupply.get()
React Hooks (requires react plugin)
import { useTokenTransfer, useTokenBalances } from './generated/hooks'
function App() {
const { transfer, isRequestPending } = useTokenTransfer()
const { data: balance } = useTokenBalances("SP...")
return (
<button onClick={() => transfer({ amount: 100n, recipient: "SP..." })}>
Transfer
</button>
)
}
Plugins
| Plugin | Description |
|---|---|
| clarinet() | Parse local Clarinet project |
| actions() | Add read/write helpers |
| react() | Generate React hooks |
| testing() | Generate Clarinet SDK test helpers |
Network Inference
Address prefix determines network:
SP/SM→ mainnetST/SN→ testnet
Use Cases
- Type-safe Clarity contract interactions
- Generate React hooks for dApps
- Testing with Clarinet SDK
- Direct integration with @stacks/transactions
