json-schema-strictly-typed

library0.0.14jsnpmunverified

A TypeScript library that provides a strictly-typed implementation of JSON Schema 7, disallowing nonsense combinations of fields. Current version 0.0.14, early-stage development with limited release cadence. Key differentiators: defines logical sub-types (e.g., JSSTIntegerWithBounds) for precise validation and includes optional faker field for strings. Alternatives like ajv focus on runtime validation, while this library emphasizes compile-time type safety with TypeScript.

Code

Verified usage

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

JSSTInteger

✓ import { JSSTInteger } from 'json-schema-strictly-typed'

✗ const JSSTInteger = require('json-schema-strictly-typed').JSSTInteger

ESM-only package; named export.

JSSTTopLevelString

✓ import { JSSTTopLevelString } from 'json-schema-strictly-typed'

✗ import { TopLevelString } from 'json-schema-strictly-typed'

Top-level types have 'TopLevel' suffix, e.g., JSSTTopLevelString.

JSSTObject

✓ import { JSSTObject } from 'json-schema-strictly-typed'

✗ import { JSSTObject } from 'json-schema-strictly-typed'

Named export, not default.

Demonstrates basic type checking for integer, string with faker, and top-level object schemas.

import { JSSTInteger, JSSTString } from 'json-schema-strictly-typed'; // Validate an integer schema const integerSchema = { type: 'integer' }; JSSTInteger.is(integerSchema); // true // Validate a string schema with faker const stringSchema = { type: 'string', faker: 'name.findName' }; JSSTString.is(stringSchema); // true // Check a top-level schema import { JSSTTopLevelObject } from 'json-schema-strictly-typed'; const topSchema = { $id: 'https://example.com/schema', type: 'object', properties: { name: { type: 'string' } } }; console.log(JSSTTopLevelObject.is(topSchema)); // true

Debug

Known issues

breakingPackage is pre-1.0; API may change without major version bump.

fix

Pin to exact version and test upgrades.

affects: <1.0

deprecatedSome JSON Schema 7 features not yet implemented (e.g., if/then/else). Use alternative libraries for full spec.

fix

Monitor GitHub for updates or switch to ajv for runtime validation.

affects: >=0.0.1

gotchaTop-level types are prefixed with 'JSSTTopLevel', not 'TopLevel' alone.

fix

Use JSSTTopLevel* names like JSSTTopLevelString, JSSTTopLevelObject.

affects: >=0.0.1

gotchaEnum types are suffixed (e.g., JSSTIntegerEnum) not generic JSSTInteger with enum values.

fix

Use JSSTIntegerEnum for integer enums, JSSTStringEnum for string enums.

affects: >=0.0.1

Errors

Common errors & fixes

Module not found: Can't resolve 'json-schema-strictly-typed'

Package not installed or ESM-only environment without proper module resolution.

fix

Install package: npm install json-schema-strictly-typed. Ensure use of ES module imports.

Property 'is' does not exist on type 'typeof import...'

Using CommonJS require() incorrectly in a TypeScript project.

fix

Change to ES module import: import { JSSTInteger } from 'json-schema-strictly-typed'.

Cannot find name 'JSSTTopLevelObject'

Importing from wrong path or forgetting the 'TopLevel' prefix.

fix

Import as: import { JSSTTopLevelObject } from 'json-schema-strictly-typed'.
