Package Exports
- detect-indent
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (detect-indent) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

var fs = require('fs');
var detectIndent = require('detect-indent');
/*
{
"ilove": "pizza"
}
*/
var file = fs.readFileSync('foo.json', 'utf8');
// tries to detect the indentation and falls back to a default if it can't
var indent = detectIndent(file) || ' ';
var json = JSON.parse(file);
json.ilove = 'unicorns';
fs.writeFileSync('foo.json', JSON.stringify(json, null, indent));
