geojson-schema

library1.0.5jsnpmunverified

Generates standalone JSON Schema documents for GeoJSON object types (Feature, Point, Polygon, etc.) as defined by RFC 7946. Current stable version is 1.0.5, released infrequently. Each schema is self-contained (no $ref dependencies), allowing consumers to fetch only what they need. Key differentiator: provides complete, non-referenced schemas ideal for offline or selective validation. Cannot validate linear ring closure or right-hand rule, requiring custom logic. Used for validating GeoJSON structures in any JSON Schema compliant validator.

Code

Verified usage

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

PointSchema

✓ const PointSchema = require('geojson-schema/Point.json')

✗ import { PointSchema } from 'geojson-schema'

Package provides raw JSON files. Use require or fetch. No ESM exports.

FeatureSchema

✓ const FeatureSchema = require('geojson-schema/Feature.json')

✗ import FeatureSchema from 'geojson-schema/Feature.json'

Use CommonJS require. ESM import with assert { type: 'json' } may work in some bundlers.

GeoJSONSchema

✓ const GeoJSONSchema = require('geojson-schema/GeoJSON.json')

✗ const GeoJSONSchema = require('geojson-schema')

Main entry point includes all types via $ref, but individual files are preferred.

Validates a GeoJSON Point using AJV with the standalone Point schema from geojson-schema.

const Ajv = require('ajv'); const ajv = new Ajv(); const PointSchema = require('geojson-schema/Point.json'); const validate = ajv.compile(PointSchema); const validPoint = { "type": "Point", "coordinates": [102.0, 0.5] }; const invalidPoint = { "type": "Point", "coordinates": [102.0] }; console.log(validate(validPoint) ? 'Valid' : 'Invalid'); // Valid console.log(validate(invalidPoint) ? 'Valid' : 'Invalid'); // Invalid console.log(JSON.stringify(validate.errors));

Debug

Known issues

gotchaCannot validate linear ring closure or right-hand rule.

fix

Implement custom validation for closed rings and right-hand rule as per RFC 7946.

affects: >=1.0.0

gotchaSchemas are self-contained; avoid combining them if you need cross-references.

fix

Use individual schemas directly; do not rely on $ref to other schemas.

affects: >=1.0.0

gotchaPackage exports raw JSON files, not JavaScript modules. ESM import may require assertions or bundler configuration.

fix

Use CommonJS require or configure your bundler to handle JSON imports.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'geojson-schema'

Importing the package as a module without specifying a JSON file path.

fix

Use require('geojson-schema/Point.json') with the specific schema file.

Error [ERR_REQUIRE_ESM]: require() of ES Module not supported

Using ESM imports with Node.js and assuming the package exports JavaScript modules.

fix

Use require() with the .json extension, or if using ESM, use createRequire or import assertion.
