Propose new module (save & read)

I seem to constantly have to write the following functions to read & save GeoJSON files (.geojson).

var truncate = require('@turf/truncate')
function read (filename) {
  return JSON.parse(fs.readFileSync(filename, 'utf8'))
}

function save (filename, features) {
  fs.writeFileSync(filename, JSON.stringify(truncate(features), null, 2))
}

An easy solution was to change the GeoJSON filename extension to (.json), but there’s many times where the data comes in as (.geojson) and I need to write this helper function.

Solution

Create a FILE SYSTEM group of functions @turf/file-system (I dunno… just throwing that out there).

For start it would have both read & save functions.

var read = require('@turf/file-system').read
var save = require('@turf/file-system').save

For people who only need fs to read & write GeoJSON this would replace require('fs') for GeoJSON purposes.

var fs =require('@turf/file-system')
fs.save('example.geojson', featureCollection)

👍 This sounds useful, I guess the big question is whether save should, by default, use truncate to limit coords.

I just used load-json-file & write-json-file in the test.js for @turf/truncate without any issues, those libraries are very easy to use and solves read & write issue I had.
