Properties Filter

An auxiliary library that allows filtering objects by its properties using JSON-serializable expressions

Installation

# latest stable
$ npm install --save-dev @nextgis/properties-filter
# or
$ yarn add @nextgis/properties-filter

Usage

General view of expression

[ С , [E1] , [E2] , [EN] ]

• С - condition (optional). May be 'all' or 'any';

• E - expression:

  [key, operator, value]

  • key - property name;
  • operator - gt, lt, ge, le, eq, ne, in, notin, like, ilike;
  • value - anything to compare with property by operator

  in and notin:

    [['id', 'in', [1,2,3]], ['id', 'notin', [1,2,3]]]
  

  like and ilike:

    Place `%`-character after or before `key` string to determine the direction of search.
  
    - ['str%', 'like', 'hello']
    - ['%str%', 'ilike', 'Worl']
  

Nesting

[ [E1], ['any', [E2], [E3, E4] ], ['any', [E5], [E6] ] ] ]

import { propertiesFilter, featureFilter } from '@nextgis/properties-filter';

const properties = {
    place: 'Tofalaria',
    area: 21
};

propertiesFilter(properties, [['name', 'eq', 'Tofalaria']]);
propertiesFilter(properties, [['name', 'in', ['Tofalaria', 'Siberia']]]);
propertiesFilter(properties, [['name%', 'like', 'Tof']]);

propertiesFilter(properties, [['name', 'eq', 'Tofalaria'], ['area', 'ge', 21]]);
propertiesFilter(properties, ['any', ['name', 'eq', 'Siberia'], ['area', 'gt', 10]]);

BREAKING CHANGES

• Vector layer adapter types were renamed: circle > point; fill > polygon.

  The `type` parameter still optional, but it is better to specify explicitly.
  

  Especially when the layer is initiated empty.

// before
webMap.addLayer('GEOJSON', { data: geojson, type: 'fill' });
// after
webMap.addLayer('GEOJSON', { data: geojson, type: 'polygon' });

• Updated libraries for linting. Added new rule for worning when no set return type in TypeScript functions.
