json.dump appears to add extraneous spaces before newline characters. By specifying the separators option, we can remove these whitespaces, reducing the diff noise. Solution taken from https://stackoverflow.com/questions/16311562/python-json-without-whitespaces DISABLE_THIRD_PARTY_CHECK=Fix whitespace in node_modules Change-Id: I26556e5053f19a9021ad41779319bdfe3f8c2b6c Reviewed-on: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/2013154 Commit-Queue: Tim van der Lippe <tvanderlippe@chromium.org> Commit-Queue: Mathias Bynens <mathias@chromium.org> Auto-Submit: Tim van der Lippe <tvanderlippe@chromium.org> Reviewed-by: Mathias Bynens <mathias@chromium.org>
Run Async
Utility method to run a function either synchronously or asynchronously using a series of common patterns. This is useful for library author accepting sync or async functions as parameter. runAsync will always run them as an async method, and normalize the multiple signature.
Installation
npm install --save run-async
Usage
Here's a simple example print the function results and three options a user can provide a function.
var runAsync = require('run-async');
var printAfter = function (func) {
var cb = function (err, returnValue) {
console.log(returnValue);
};
runAsync(func, cb)(/* arguments for func */);
};
Using this.async
printAfter(function () {
var done = this.async();
setTimeout(function () {
done(null, 'done running with callback');
}, 10);
});
Returning a promise
printAfter(function () {
return new Promise(function (resolve, reject) {
resolve('done running with promises');
});
});
Synchronous function
printAfter(function () {
return 'done running sync function';
});
runAsync.cb
runAsync.cb supports all the function types that runAsync does and additionally a traditional callback as the last argument signature:
var runAsync = require('run-async');
// IMPORTANT: The wrapped function must have a fixed number of parameters.
runAsync.cb(function(a, b, cb) {
cb(null, a + b);
}, function(err, result) {
console.log(result)
})(1, 2)
If your version of node support Promises natively (node >= 0.12), runAsync will return a promise. Example: runAsync(func)(arg1, arg2).then(cb)
