library0.1.0jsnpmunverified

Doba is a TypeScript schema registry for type-safe data transformations and migrations between different schema variants (e.g., database, frontend, AI contexts). Built on Standard Schema, it supports any Zod, Valibot, or ArkType schemas. Version 0.1.0 is early-stage but functional: O(1) lookup for schemas, graph-based migration path finding, and errors as values. It distinguishes itself from manual transform functions by providing automatic path finding, hops scaling at ~140ns each, and hook support for logging/validation. Release cadence is unknown (pre-1.0).

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

createRegistry

✓ import { createRegistry } from 'doba'

✗ const { createRegistry } = require('doba')

ESM-only package; requires Node 20+ or bundler with ESM support.

Registry

✓ import type { Registry } from 'doba'

✗ import { Registry } from 'doba'

Registry is exported as a type only. Do not use at runtime.

Schema

✓ import type { Schema } from 'doba'

Type representing an inferrable Standard Schema; useful for parameter annotations.

TransformResult

✓ import type { TransformResult } from 'doba'

Result type from transform(): { ok: boolean, value?: T, error?: StandardSchemaV1Error }

Creates a registry with two schemas and a migration, transforms data from 'db' to 'pub' (stripping secret), and logs the result.

import { createRegistry } from 'doba' import { z } from 'zod' const dbSchema = z.object({ id: z.string(), name: z.string(), secret: z.string() }) const pubSchema = z.object({ id: z.string(), name: z.string() }) const registry = createRegistry({ schemas: { db: dbSchema, pub: pubSchema }, migrations: { 'db->pub': (user) => ({ id: user.id, name: user.name }), }, }) const input = { id: '1', name: 'Alice', secret: 'shh' } const result = await registry.transform(input, 'db', 'pub') if (result.ok) { console.log(result.value) // { id: '1', name: 'Alice' } }

Debug

Known issues

gotchaMigrations must be explicitly registered between every pair you intend to use. Automatic path finding only works if intermediate schemas exist.

fix

Add all required migration edges, or ensure a path exists via intermediate schemas.

affects: >=0.1.0

gotchaThe package ships only ESM. CommonJS require() will fail.

fix

Use dynamic import() or switch to an ESM-compatible project.

affects: >=0.1.0

deprecatedVersion 0.1.0 is pre-release and API may break. Not recommended for production use.

fix

Pin to exact version and test after each upgrade.

affects: >=0.1.0

gotchaThe transform() function is async even if migrations are synchronous. This allows future hook support.

fix

Always await or use .then() on transform calls.

affects: >=0.1.0

Errors

Common errors & fixes

Cannot find module 'doba' or its corresponding type declarations.

Package not installed, or TypeScript cannot resolve ESM exports.

fix

Run 'npm install doba' and ensure 'moduleResolution' is 'bundler' or 'node16' in tsconfig.

SyntaxError: Unexpected token 'export'

Node.js version <20 or CommonJS context does not support ESM syntax.

fix

Upgrade Node to 20+ or use a bundler (esbuild, webpack) with ESM output.

TypeError: registry.transform is not a function

Incorrect import (e.g., imported Registry type instead of createRegistry function).

fix

Use 'import { createRegistry } from 'doba'' and call createRegistry(), then use the returned registry instance.

Error: No migration path from 'schemaA' to 'schemaB'

No direct migration edge or path via intermediate schemas exists.

fix

Register a migration like 'schemaA->schemaB' or ensure intermediate schemas are connected.
