Jake's documentation states that directory-tasks create a directory for use with for file-tasks. Jake checks for the existence of the directory, and only creates it if needed.
Example:
desc('This creates the bar directory for use with the foo-minified.js file-task.');
directory('bar');
I have not been able to get this to work inside or outside of a file-task. Anyone know what I'm doing wrong?
I was running Node v0.5.0-pre and updated to v0.6.6. Still no luck. I've filed an official ticket, but see if anyone knows if I've just been using it wrong.
In the meantime I just wrote and am using:
/* Checks if directory exists, creates if needed with optional created callback. */
function directory(dir, callback){
if (!path.existsSync(dir)){
console.log(dir + " folder doesn't exist. Creating...");
fs.mkdirSync(dir);
if (callback){
callback(dir);
}
}
}

Just wondering if anyone has ever attempted to copy a directory from an external drive (connected via USB) to a local folder.
I am using ElectronJS so I can use my JavaScript, HTML/CSS skills to create a desktop application without utilising a C language. (i.e. C# or C++) With ElectronJS there's a lot less to worry about.
Here is the list of things I've tried so far:
basic fs.copyFile (using copyFile intially and will then loop round the directory to copy all files)
var fs = require('fs');
window.test = () => {
fs.moveSync("targetFile","destDir", function(err) {
if(err){
console.log(err);
}else{
console.log("copy complete")
}
});
}
fs.moveSync is not a function even though Visual Studio Code brought up moveSync as a suggestion when I entered fs. (ctrl + space)
using child_process functions to copy files using the command line.
Code is:
var process = require('child_process')
window.test = function(){
process.exec('ipconfig', function(err, stdout, stderr){
if(err){
console.log(err);
}else{
console.log(stdout)
}
})
}
Then bundled with browserify. Bundle.js is then imported into the html file and the test function is called on the click of a button. I'm aware the command is ipconfig for now, this was merely used to see if a command could be executed. It appears it could because I was getting process.exec is not defined.
use the node-hid node module to read and trasfer data from the external drive.
The exposed functions within this module were also reported as being undefined. And I thought about the use case longer I thought a simple copy process would suffice because external drive can be accessed like any other folder in the file explorer.
Unfortunately, all of the above have failed and I've spent the most part of the day looking for alternative modules and/or solutions.
Thanks in advance because any help to achieve this would be much appreciated.
Thanks

The npm package fs-extra should solve your problem.
It has the move function, which
Moves a file or directory, even across devices
Ended up adding this to my preload.js for:
window.require = require;
It will work for now but is due to be depreciated.
I'll use this for now and make other updates when I have to.
I was wondering what's the best practice and if I should create:
a directory in which declare statically all the errors my application uses, like api/errors/custom1Error
declare them directly inside the files
or put the files directly inside the dir that needs that error, like api/controller/error/formInvalidError
other options!?
A neat way of going about this would be to simply add the errors as custom responses under api/responses. This way even the invocation becomes pretty neat. Although the doc says you should add them directly in the responses directory, I'm sure there must be a way to nest them under, say, responses/errors. I'll try that out and post an update in a bit.
Alright, off a quick search, I couldn't find any way to nest the responses, but you can use a small workaround that's not quite as neat:
Create the responses/errors directory with all the custom error response handlers. Create a custom response and name it something like custom.js. Then specify the response name while calling res.custom().
I'm adding a short snippet just for illustration:
api/responses/custom.js:
var customErrors = {
customError1: require('./errors/customError1'),
customError2: require('./errors/customError2')
};
module.exports = function custom (errorName, data) {
var req = this.req;
var res = this.res;
if (customErrors[errorName]) return customErrors[errorName](req, res, data);
else return res.negotiate();
}
From the controller:
res.custom('authError', data);
If you don't need logical processing for different errors, you can do away with the whole errors/ directory and directly invoke the respective views from custom.js:
module.exports = function custom (viewName, data) {
var req = this.req;
var res = this.res;
return res.view('errors/' + viewName, data);//assuming you have error views in views/errors
}
(You should first check if the view exists. Find out how on the linked page.)
Although I'm using something like this for certain purposes (dividing routes and so on), there definitely should be a way to include response handlers defined in different directories. (Perhaps by reconfiguring some grunt task?) I'll try to find that out and update if I find any success.
Good luck!
Update
Okay, so I found that the responses hook adds all files to res without checking if they are directories. So adding a directory under responses results in a TypeError from lodash. I may be reading this wrong but I guess it's reasonable to conclude that currently it's not possible to add a directory there, so I guess you'll have to stick to one of the above solutions.
Question is too broad / unclear. Anyone interested in this answer would be better served by visiting: Creating Callbacks for required modules in node.js
Basically I have included a CLI package in my node application. I need the CLI to spin up a new project (this entails creating a folder for the project). After the project folder is created, I need to create some files in the folder (using fs writeFile). The problem is right now, my writeFile function executes BEFORE the folder is created by the CLI package (This is detected by my console.log. This brings me to main main question.
Can I add an async callback function to the CLI.new without modifying the package I included?
FoundationCLI.new(null, {
framework: 'sites', // 'apps' or 'emails' also
template: 'basic', // 'advanced' also
name: projectName,
directory: $scope.settings.path.join("")
});
try{
if (!fs.existsSync(path)){
console.log("DIRECTORY NOT THERE!!!!!");
}
fs.writeFileSync(correctedPath, JSON.stringify(project) , 'utf-8');
} catch(err) {
throw err;
}
It uses foundation-cli. The new command executes the following async series. I'd love to add a callback to the package - still not quite sure how.
async.series(tasks, finish);
Anyone interested in this can probably get mileage out of:
Creating Callbacks for required modules in node.js
The code for the new command seem to be available on https://github.com/zurb/foundation-cli/blob/master/lib/commands/new.js
this code was not written to allow programmatic usage of the new command (it uses console.log everywhere) and does not call any callback when the work is finished.
so no there is no way to use this package to do what you are looking for. Either patch the package or find another way to do what you want to achieve.
This is probably a stupid one but I have tried all the things I can think of. I am currently getting the below error on my client side script when I try and execute it.
Error: ReferenceError acvt_serialNumber_saveRecord is not defined
On the Script record in Netsuite I have set the saveRecord function as follows:
acvt_serialNumber_saveRecord
The code in the file is:
function acvt_serialNumber_saveRecord(){
/**do stuff */
}
I have reuploaded to code to make sure the right version was in NetSuite. I have added one character to both the script fn name and the fn name on the Script record (as a shot in the dark). I have seen in the Javascript console at runtime that the correct code is in there and I can see the exact function name (I did a ctrl+f for the "undefined" function in the code in the console to make sure spelling was all the same).
NOTHING has worked. I had this code working earlier, but the changes I made were not to this function at all.
Any help is appreciated
Another thing to check is the code that you recently changed. In particular, check for a hanging comma. IE:
var someObj = {
someProp:'somevalue',
};
The comma at the end of 'somevalue' will cause the script to fail, throwing 'undefined' errors.
Have you tried deleting the Script record in NetSuite and re-creating it?
Do you have any library included for that Client Script in netsuite ?
Provide a screen shot of your Netsuite script page
I encounter similar problem like this before, but it was because i called a function which is inside a library file
Thanks
I'm trying to use mkdirp for a project, but when I feed it a var with my dir path I want created, it only creates the first half of it. I've installed the module locally with npm. I'm using Node v0.10.20 on a Raspberry Pi.
This is how it looks:
var filePath = "upload/home/pi/app/temp";
mkdirp(filePath, function(error) {
if(error) {
console.log(error);
} else {
...
}
});
I don't get an error creating the path, but it only creates "upload/home/pi", however if I run my script again, it creates the rest of the directory structure. Upload is a
directory in the current working directory which is the user home.
I emailed the author of the module who suggested that it could be because I'm using a flash drive as my medium, which in turn lies about when IO operations are complete, which I guess confuses node.js to think it has successfully written the path to disk. How should I tackle my problem? I guess I can do a check on if the directory was created, and loop that until it has, but that feels like the wrong thing to do. Any suggestions welcome.
Thanks.
Try doing this synchronously:
var filePath = "upload/home/pi/app/temp";
mkdirp(filePath)
