Running gulp tasks in sibling folder - node.js

Let's say I need to run a gulp command to build some assets.
Assume I am at root folder, I have a dir called ./node_modules/semantic-ui/, that requires to run 'gulp build' to get necessary assets.
I also setup an npm command, called
build:semantic': 'gulp ./node_modules/semantic-ui'
but it is not possible to do so and I am not willing to use cd command inside my npm run command.
What can I do to do so? Thanks.

Gulp allows you to pass a --cwd and if you do that it will run from within that directory. So in your case, you do this:
gulp --cwd './node_modules/semantic-ui'
Hope that helps. Let me know if it doesn't.

npm - run scripts in directory other than cwd

I have a script which scaffolds an app. This involves making a new directory in the current directory inside which the app's scaffold files will be unpacked.
At the end of my script I run a series of npm/node commands as follows (appDir is a reference to the child dir created to host the app; it exists by the time these commands run):
const postInstCmds = [
'cd '+appDir,
'npm init -y',
'npm install add-npm-scripts --save-dev',
'npm install http-server --save-dev',
'add-npm-scripts server "http-server"',
'npm run server'
];
const execSync = require('child_process').execSync;
postInstCmds.forEach(cmd => execSync(cmd));
However it seems the first cd command is being ignored; the subsequent commands are being executed in the parent, not child, directory.
I've read this, which explicitly says that npm supports cd * operations, but perhaps I'm misunderstanding something (I'm no npm wizard). I've also tried using npm's --prefix argument to specify path, but no joy.
[UPDATE]
The linked dup suggests npm start <dir> but this seems to work only if <dir> already contains a package.json. As per my sequence of commands, I want to move to the directory and then create the package.json (via npm init). Another answer there suggests npm run --prefix, but run again requires an extant pacakge.json, since it reads from the scripts object.
I have also tried npm init --prefix <dir> but the arg doesn't seem to be supported for npm init.
Your code is running different child processes for each command. So the cd command runs in a subprocess and exits. Then the next command runs in a new subprocess that is in the original directory you started in and not in the directory that the cd command navigated to.
One fix would be to get rid fo the cd command and instead pass the directory as a cwd option for each execSync() call.
postInstCmds.forEach(cmd => execSync(cmd, {cwd: appDir}));

BrowserSync: command not found after installing locally

I ran the following command for my node app:
$ npm install browser-sync --save-dev
Installation was successful, browser-sync appears in my package.json file as well as my node_modules directory.
However, when I run $ browser-sync --version to check that it's working, I get the following error:
bash: browser-sync: command not found
Why isn't this working?
Note: this question is similar, but I don't want to have to install it globally as in this question.
Any help would be greatly appreciated!
This is because you're trying to use a module locally which is normally installed globally. Modules installed globally end up on your PATH environment variable, which is why you can run them from the terminal as you're trying to do:
$ browser-sync --version
If you want to use the browser-sync module from a local install you will have to prepend the full path to the browser-sync binary from within your .bin directory since all locally installed modules are placed within your current working directory node_modules directory. i.e. Node modules go in ./node_modules, executables go in ./node_modules/.bin/. So in order to run the browser-sync binary from a local install do the following:
./node_modules/.bin/browser-sync --version
Hopefully that helps!
If you installed browser-sync using npm --save or npm --save-dev you can run it by writing a script in your package.json. Here's an example of a script I added:
{
...
"scripts": {
"dev-server": "browser-sync start --server 'public' --files 'public'"
},
...
}
You can run the scripts from you project's root directory like so
npm run dev-server
This will run whatever command is set to dev-server in your script. In this case it will run browser-sync for the app/site in a folder called /public and watch for any file changes in the /public folder. I know this question is a bit old but it was unanswered and hopefully I can save someone time in the future.
The other answers still work, but a newer approach has emerged since npm added the npx command: npx <package-name>.
This command allows you to run an arbitrary command from an npm
package (either one installed locally, or fetched remotely), in a
similar context as running it via npm run.
Source: https://docs.npmjs.com/cli/v8/commands/npx
In this case, you would run npx browser-sync.

Locally installed gulp not running in command line?

I am new to nodejs and gulp stuff. I working on a nodejs project in which I have to run jslint on all the files. I am using gulp for this purpose.
My problem is that In order to run gulp on cli I don't want to install gulp globally and also does not want to update my path variable, So I have installed gulp and other node modules in my project locally using the package.json file
cd myproject
npm install
Since I don't want to install gulp globally and want to run the local gulp I have added script in my package.json file like this as given in this question
{
"name": "",
"version": "1.0.0",
"main": "index.js",
"private": true,
"dependencies": {
"async": "1.5.0"
},
"devDependencies": {
"gulp": "^3.9.0",
"gulp-jslint": "^0.2.2"
},
"scripts": {
"gulp": "./node_modules/.bin/gulp" // is this correct?
}
}
Add added a gulpfile.js inside my myproject folder
var gulp = require('gulp');
// include plug-ins
var jslint = require('gulp-jslint');
// JS hint task
gulp.task('lint', function() {
gulp.src('./common/srp/*.js')
.pipe(jslint())
.pipe(jslint.reporter('default'));
});
gulp.task("default", ["lint"]);
But now on my command line inside myproject folder, when I run gulp and gulp lint I get an error
user1-VirtualBox:~/myproject$ gulp lint
/usr/local/node-v0.10.26-linux-x64/bin/gulp No such file or
directory
Its looking for gulp in the global node module.
Is there a way to make gulp run on cli without installing globally and updating PATH variable.
Any help will be appreciated
Thanks
You can find any executable installed by npm in node_modules/.bin. So you can run gulp locally using:
./node_modules/.bin/gulp
You can find more information at no command 'gulp' found - after installation
With your code you should be able to run command
npm run gulp
Please try
One way to define script is
"scripts": {
"gulp": "gulp"
}
If in case you are not able to run gulp command in your project, run
npm link gulp
It will link your global install gulp with your local project. Then try
gulp -v
If it is showing you the version then you are done. Now you can run any gulp command as you want.
Scripts defined in package.json are accessed through NPM, i.e. npm run-script gulp. I imagine you're trying to run plain old gulp, which should fail since you didn't install it globally.
The scripts section won't automatically create an alias, which I think is your mistake here. You could define one yourself or create a simple bash script if you don't want to type it every time.
Try:
path_to_node path_to_gulp_js gulp_task
Example:
node\node.exe node_modules\gulp\bin\gulp.js build
Like #snorberhuis said. The only way for me to get gulp to work globally was to call gulp manually
I am building in a Jenkins environment
Execute Windows Batch Command
cd your-app
npm install gulp
Execute Windows Batch Command
cd your-app\node_modules\.bin
gulp
Just another alternative that will work locally but will give you global like feeling.
Add to your shell config i.e. ~/.bash_profile the following
export PATH=$PATH:./node_modules/.bin
you have to source that file, execute rehash or just open a new shell and then gulp (and any other script inside that folder) shall be available as a global command.
The way I did this after bashing my head every possible place is simply going to your Application and install npm dependencies like this:
1- E:\webra-jenkins\Code\trunk\WebRa.Web>npm install
Once npm installed then go this directory
2- [%Application_path%]\node_modules\.bin
And execute the gulp and give your file/task, like this:
3-[%Application_path%]\node_modules\.bin>gulp gulpfile --tasks
In my case as I saw the following lines... I got the inner happiness
18:06:36] Working directory changed to [%Application_path%]
[18:06:37] Tasks for [%Application_path%]\gulpfile.js
Now you can run your tasks 1 by one.
[%Application_path%]\node_modules\.bin>gulp pack-vendor-js
Check in your project node_modules/.bin folder and make sure gulp is in there. I had a case where it wasn't there that I never tracked down the reason for. If it isn't there, try re-installing gulp locally and see if it shows up. If that doesn't work and you get tired of the problem, the gulp-cli package will fix it for sure, but that shouldn't be something you have to do.
The simplest solution I know of is to use npm bin:
`npm bin`/gulp ...
This keeps you away from hard-coding any paths.
Nothing was working for me. I followed all instructions from everyone. No matter what I did I could not run the Gulp commands.
To fix this I opened the Node.js command prompt that comes installed automatically when you download and run node.js.
Once I was in this command prompt I could run the following commands:
npm install -g gulp
gulp -v
This is probably a matter of common knowledge but as someone starting out no one suggested to run the node.js command prompt and install gulp from there. Everything I read talked about regular powershell or command prompts with elevated permissions.
Globally install gulp in C:\Users\%USERNAME% using this command
npm install –g gulp
You can install any other gulp methods you need to use.. Ex:
npm install -g gulp-concat
npm install -g gulp-uglify
npm install -g gulp-replace
Then at the directory you wish to use GULP. Open the command prompt (Shift + RightClick) then install locally and you'll be able to execute gulp.
npm install gulp
You can install any other gulp methods you need to use.. Ex:
npm install gulp-concat
npm install gulp-uglify
npm install gulp-replace

How do you run gulp if gulp is installed(node_modules) in different folder than gulpfile.js

I have gulpfile.js in one directory and node_modules in another.
When I run gulp, i get the error -
'Local gulp not found in '..(the directory)..
Try running: npm install gulp'
The thing is - I cannot install gulp in the directory of gulpfile.js and so I need a way to tell the gulp to refere to the other directory i have gulp installed in.
You don't need to install gulp globally if you don't want to. What you can do is run your gulp executable (from your node_modules) and then pass in the location of your gulpfile using the --gulpfile parameter. Also, if you want to control where your gulp is running, make use of the --cwd parameter.
Here's an example:
<NODE_MODULES DIR>/gulp/bin/gulp.js --gulpfile <GULP FILE> --cwd <SOME DIR>
There is no need to install gulp globally.
First install gulp (ideally on dev dependencies)
npm install gulp --save-dev
Then in the package.json add the line you want to run
"scripts" : {
"gulp" : "gulp"}
}
Finally in the command line use
npm run gulp
npm will use the binary from the node modules without any need to install it globally or to write down the whole path
You need to install gulp globally:
npm install -g gulp
This will allow you to run gulp from the command line in any directory.
Put the node_modules folder in parent directory always, then make project directory as child/grandchild folder.
Don't put the node_modules folder in any child directory
Folder structure will be like:
parent
└──node_modules
└─project_1
└─project_2
In any child/grand child directory gulp will work

NPM: Change the `bin` output directory for the node modules

Currently, if you are using a package.json file to manage your project's dependencies (whatever project it is, may it be a ruby, php, python or js app), by default everything is installed under ./node_modules.
When some dependencies have binaries to save, they're installed under ./node_modules/.bin.
What I need is a feature that allow me to change the ./node_modules/.bin directory for ./bin.
Simple example:
A PHP/Symfony app has a ./vendor dir for Composer dependencies, and all binaries are saved in ./bin, thanks to the config: { bin-dir: bin } option in composer.json.
But if I want to use Gulp to manage my assets, I create a package.json file, require all my dependencies and then run npm install.
Then, my wish is to run bin/gulp to execute gulp, but actually I have to run node_modules/.bin/gulp which is not as friendly as bin/gulp.
I've looked at package.json examples/guides on browsenpm.org and docs.npmjs.com, but none of them works, because they are here to define your own project's binaries. But I don't have any binaries, because I want to use binaries from other libraries.
Is there an option for that with NodeJS/NPM ?
You might consider adding gulp tasks to your package.json.
// package.json
{
"scripts": {
"build-templates": "gulp build-templates",
"minify-js": "gulp minify-js"
}
}
You can run any scripts specified in package.json by simply running the following:
$ npm run build-templates
$ npm run minify-js
You get the idea. You can use the gulp command inside the string without doing ./node_modules/.bin/gulp because npm is smart enough to put all scripts from ./node_modules/.bin/ into the path for that script execution.
