Releases: Turfjs/turf
Fix turf-line-slice snapping bug
- removes vendored point-on-line implementation in favor of a local dependency
- add test fixture for vertical linestrings passed to turf-line-slice
Fix turf-along using raw geometry
Fix turf-collect
This publishes turf-collect, which was previously incorrectly named turf-aggregate
Initial 3.x release
This is a big change in Turf! 3.0.0 is a release that targets the development
cycle of Turf, letting us work on it more and release more often.
Monorepo
Turf 3.x and forward is a monorepo project. We publish lots of little modules
as usual, but there's one repo - turfjs/turf - that contains all the code
and the issues for the Turf source code. We use lerna
to link these packages together and make sure they work.
Why? We already had internal turf modules, like turf-meta
, and development
was harder and harder - we had a bunch of custom scripts to do releases and
tests, and these were just written for Turf. Lerna is from the very popular
and very well-maintained babel project, and it
works really well, and reduces maintainer sadness.
Simplicity
Turf grew a bunch of modules that weren't totally necessary, or were
expressing only a line or two of JavaScript. We want to make things easier,
but these modules didn't make code more expressive and they hid complexity
where it didn't need to be hidden. Turf 3.x focuses on the core
functionalities we need, making sure they're tested and performant.
Removed modules: merge, sum, min, max, average, median, variance, deviation, filter, remove, jenks, quantile.
See the upgrade guide below for replacements.
Upgrading from v2
If you were using turf-merge
turf-merge repeatedly called turf-union on an array of polygons. Here's
how to implement the same thing without the special module
var clone = require('clone');
var union = require('turf-union');
function merge(polygons) {
var merged = clone(polygons.features[0]), features = polygons.features;
for (var i = 0, len = features.length; i < len; i++) {
var poly = features[i];
if (poly.geometry) merged = union(merged, poly);
}
return merged;
}
If you were using turf-sum, min, max, average, median, variance, deviation
The turf-collect
method provides the core of these statistical methods
and lets you bring your own statistical library, like simple-statistics
,
science.js
, or others.
If you were using turf-filter, turf-remove
These modules were thin wrappers around native JavaScript methods: use
Array.filter instead:
var filteredFeatures = features.filter(function(feature) {
return feature.properties.value > 10;
});
If you were using turf-jenks, turf-quantile
Use Array.map to get values, and then bring your own statistical calculation,
like simple-statistics or science.js.
var values = features.map(function(feature) {
return feature.properties.value;
});
v2.0.0
- turf-grid renamed turf-point-grid (turf.grid => turf.pointGrid)
- turf-hex renamed turf-hex-grid (turf.hex => turf.hexGrid)
- turf-hex-grid now has a required
unit
parameter - remove turf-isobands; use turf-isolines instead
- added turf-square-grid (turf.squareGrid)
- added turf-triangle-grid (turf.triangleGrid)
- constrain turf-point-grid to the bbox

unit
parameter to turf.concave
v1.3.5

v1.3.4
- fix issue with turf-along
v1.3.3
