applyConverter missing?

[allmondjoy87]

How do I use the applyConverter tool with the latest release?

[jgravois]

import { applyConverter } from '@terraformer/spatial'
// Runs the passed function against every Coordinate in the geojson object. 
// Your function will be passed a Coordinate and will be expected to return a Coordinate.
applyConverter(geojson, yourFunction);

if someone is interested in adding JSDoc for the method to ensure it shows up in the documentation, that'd be welcome.

[allmondjoy87]

aha!! I was getting "TypeError: Object(...) is not a function" errors and assumed it was an issue with my converter function.

After digging a little deeper applyConverter is missing in the exports section in the t-spatial.esm.js and t-spatial.umd.js files. I added it in my source code and everything's gravy.

[jgravois]

if someone wants to export the utility function in the file below and add JSDoc, i'd be more than happy to publish the change.

looks like this hasn't been updated yet, any chance someone can make the fix? is this something i can do? i've never contributed to a project before, unsure what the rules are.

absolutely. to do this you'd just need to:

1. clone the repo
2. run npm install && npm test locally to ensure all is well
3. add the relevant export in packages/spatial/src/index.js
4. supplement that export with the JSDoc below
5. run npm run doc to update the README for the spatial package to mention the new method
6. run npm test again to confirm all is still well
7. commit the result in your own branch and open up a PR

/**
 * Runs the passed function against every Coordinate in the geojson object.
 * @function
 * @param {object} GeoJSON - The input [GeoJSON](https://tools.ietf.org/html/rfc7946) Geometry, Feature, GeometryCollection or FeatureCollection.
 * @param {function} function - Your function will be passed a Coordinate and will be expected to return a Coordinate.
 * @return {object} GeoJSON - [GeoJSON](https://tools.ietf.org/html/rfc7946) with altered coordinates.

 *
 * >> { type: "Point", coordinates: [ 46, 59 ] }

Well I'm having issues with npm-install. Getting tarball and ultimately EINTEGRITY errors when it tries to install jison@git+ssh.

However I saw you very recently made a branch "patch-68" that looks like it handles the fix! Whats up with that?

[jgravois]

if you use Node.js 16x or 17x, the install should succeed.

patch-68 can't be merged as is. it has a bunch of unrelated whitespace changes.

[allmondjoy87]

node --version
v16.14.0

Failing w/ 16x. npm cache verify and npm cache clean --force didn't help either.

I'll update to 17x and give it a shot.

[jgravois]

Failing w/ 16x

hmmm, that's a surprise.

Well I'm having issues with npm install

i think what i did in #87 will fix your issue.
