const { createWriteStream, watch, readFileSync } = require('fs');
const doc = '{ "a": 1 }';
const filename = '/tmp/reproducer.txt';
const outStream = createWriteStream(filename);
setTimeout(() => outStream.write(doc), 2000);
const watcher = watch(filename, function(eventType) {
assert.equal(eventType, 'change');
var fileContents = readFileSync(filename, 'utf8');
try {
var parsedFileContents = JSON.parse(fileContents);
assert.equal(parsedFileContents.a, 1);
console.log('success');
} catch (e) {
console.log(e);
console.log(`JSON contents: \`${fileContents}\``);
} finally {
