geojsonhint: complete, fast, standards-based validation for geojson

Important: development of geojsonhint is currently paused. Until development restarts, please refrain from adding non-critical issues or PRs.

A lint tool for the GeoJSON standard. geojsonhint is written to the standard, with no missing or additional opinions about structure.

Thanks to jsonlint-lines, GeoJSON that is also not valid JSON can return informative, line-oriented parsing errors.

Specification

The basis of this tool is the published GeoJSON specification.

API

errors = geojsonhint.hint(string or object, options)

Lint a file, given as a string or object. This call detects all aberrations from the GeoJSON standards and returns them as an array of errors. An example of the output:

[{
  "message": "\"features\" property should be an array, but is an object instead",
  "line": 1
}]

The options argument is optional. It has these options:

noDuplicateMembers.

By default, geojsonhint will treat repeated properties as an error: you can set noDuplicateMembers to false to allow them. For instance:

geojsonhint.hint('{"type":"invalid","type":"Feature","properties":{},"geometry":null}', {
    noDuplicateMembers: false
});

The repeated type property in this input will be ignored with the option, and flagged without it.

precisionWarning.

GeoJSON now recommends six decimal places of accuracy for coordinates (Section 11.2). This option adds a warning message when coordinates contain over 6 decimal places of accuracy, up to 10 coordinates before the warning message is truncated for performance.

geojsonhint.hint('{ "type": "Point", "coordinates": [100.0000000001, 5.0000000001] }', {
    precisionWarning: false
});

With this option enabled, geojsonhint will produce these warnings:

[{
  line: 1,
  level: 'message',
  message: 'precision of coordinates should be reduced'
}, {
  line: 1,
  level: 'message',
  message: 'precision of coordinates should be reduced'
}]

Without this option, this input will pass without errors.

Line Numbers

Note that the GeoJSON can be given as a string or as an object. Here's how to choose which input to use:

  • string inputs receive line numbers for each error. These make errors easier to track down if the GeoJSON is hand-written.
  • object inputs don't have line numbers but are evaluated faster, by up to 10x. GeoJSONHint is very fast already so unless you have identified it as a bottleneck in your application, don't prematurely optimize based on this fact.

If you're really trying to save space and don't care about JSON validity errors - only GeoJSON errors - you can require('geojsonhint/lib/object') to get a version of this library that bypasses jsonlint-lines and provides only the object interface.
