project.json scripts events can delete folders? - asp.net-core

I am trying to delete a folder on post compile but cant make rd or del commands to work. Is there a way to delete a folder and subfolders from the scripts events?

Put the commands that you need in a batch or shell file and invoke that file in the post compile step

Use npm and gulp task, that not depends on the OS
Add a package.json file in your project root with gulp and gulp-rimraf dependencies:
{
"version": "1.0.0",
"description": "your description",
"name": "your project name",
"readme": "yuour readme",
"license": "Apache-2.0",
"dependencies": {
},
"devDependencies": {
"gulp": "3.9.1",
"gulp-rimraf": "0.2.0",
},
"scripts": {
"gulp": "gulp",
}
}
Add a gulpfile.js in your project root containing the cleanup task :
/// <binding Clean='clean' />
"use strict";
var gulp = require("gulp"),
rimraf = require("gulp-rimraf");
gulp.task("clean:js", function (cb) {
return rimraf("path to js folder to delete", cb);
});
gulp.task("clean:css", function (cb) {
return rimraf("path to css folder to delete", cb);
});
gulp.task("default", ["clean:js", "clean:css"]);
In your project.json, call the npm script :
{
...
"scripts": {
"precompile": "npm run gulp" // this will call the default gulp task
},
}
For more information, you can read the doc about how to use gulp on the asp.net docs site
You can do the same using grunt instead of gulp if you want

grunt-package-modules cannot install dependency of itself

I'm trying to use the npm package grunt-package-modules to gather my npm_module dependencies for a bundled deployment but ran into the error when running the command grunt packageModules:
Fatal error: Refusing to install test as a dependency of itself
This error typically occurs when the name of the project also appears in the list of dependencies in package.json as was the case here, but that does not occur in the original file or the one that is copied into the dist folder.
I was able to get this error with the simplest project setup I could create from the examples given in the grunt tutorial and the package wiki. Is there something I'm missing in setting up this plugin?
package.json
{
"name": "test",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"underscore": "^1.8.3"
},
"devDependencies": {
"grunt": "^1.0.1",
"grunt-package-modules": "^1.0.0"
}
}
Gruntfile.js
module.exports = function(grunt) {
grunt.initConfig({
packageModules: {
dist: {
src: 'package.json',
dest: 'dist'
},
}
});
grunt.loadNpmTasks('grunt-package-modules');
}
I'm on a PC and had the same thing happen on my home PC but had my co-worker run through this same setup on his mac and it worked successfully for him. Also tried updating node and npm since we had different versions with no luck.

GULP: gulp is not defined

As shown in the screen shot below I am not able to run gulp to concat the JavaScript files. Its saying that gulp is not defined.
I have tried the following commands:
npm install -g gulp
npm install gulp
npm install gulp --save-dev
I have also set the environment variables as following:
C:\Users\<user>\AppData\Roaming\npm;C:\Python27;C:\Users\<user>\AppData\Roaming\npm\node_modules;C:\Users\<user>\AppData\Roaming\npm\node_modules\gulp;
var concat = require('gulp-concat');
var rename = require('gulp-rename');
var uglify = require('gulp-uglify');
//script paths
var jsFiles = 'scripts/*.js',
jsDest = 'dist/scripts';
gulp.task('scripts', function() {
return gulp.src(jsFiles)
.pipe(concat('scripts.js'))
.pipe(gulp.dest(jsDest));
});
you just need to install and require gulp locally, you probably only installed it globally
At the command line
cd <project-root> && npm install --save-dev gulp
In your gulpfile.js
var gulp = require('gulp');
this is a different dependency than the command line dependency (that you installed globally). More specifically, it is the same NPM package, but the command line program will execute code usually from a different entry point in the NPM package then what require('X') will return.
If we go to the package.json file in the Gulp project on Github, it will tell the whole story:
{
"name": "gulp",
"description": "The streaming build system",
"version": "3.9.1",
"homepage": "http://gulpjs.com",
"repository": "gulpjs/gulp",
"author": "Fractal <contact#wearefractal.com> (http://wearefractal.com/)",
"tags": [ ],
"files": [
// ...
],
"bin": {
"gulp": "./bin/gulp.js"
},
"man": "gulp.1",
"dependencies": {
// ...
},
"devDependencies": {
// ...
},
"scripts": {
"prepublish": "marked-man --name gulp docs/CLI.md > gulp.1",
"lint": "eslint . && jscs *.js bin/ lib/ test/",
"pretest": "npm run lint",
},
"engines": {
"node": ">= 0.9"
},
"license": "MIT"
}
so at the command line:
$ gulp default
will execute this:
"bin": {
"gulp": "./bin/gulp.js"
},
on the other hand, require('gulp') in your code will return the value of this:
https://github.com/gulpjs/gulp/blob/master/index.js
normally we see this in a package.json file as:
"main": "index.js"
but since this is the default, they just omitted it (which is dumb IMO, better to be explicit, but they aren't the first project I have seen take the lame shorthand route.).
Its occurs on Windows and usually one of the following fixes it:
If you didn't, run npm install gulp on the project folder, even if
you have gulp installed globally.
Normally, It isn't a problem on Windows, but it could be a issue with
the PATH. The package will try to get the PATH from the environment,
but you can override it by adding exec_args to your gulp settings.
For example, on Ubuntu:
"exec_args": {
"path": "/bin:/usr/bin:/usr/local/bin"
}
Hope It will be OK.

using local less with npm

Are there any established patterns for running less via npm scripts?
for instance, in my package.json file I have:
{
"name": "lesstest",
"description": "less test",
"main": "dist/index.js",
"scripts": {
"build:css": "./node_modules/less/bin/lessc src/less/app.less dist/style.css"
},
"devDependencies": {
"less": "^2.6.0",
}
}
running:
./node_modules/less/bin/lessc src/less/app.less dist/style.css
from terminal works just fine, but when I run
npm run build:css
I get " '.' is not recognized as an internal or external command,
operable program or batch file. " Does this mean that commands in npm scripts cannot include paths? If so, are there any techniques out there to execute a similar intention without using gulp?
You can just use "lessc src/less/app.less dist/style.css"
By default, package.json looks in your node_modules folder, and if it can't find it, looks elsewhere, so you can safely use a downloaded dependency as if you had globally installed it.
I just want to clarify #JRJurman's answer a bit. You can use lessc like this:
{
"name": "lesstest",
"description": "less test",
"scripts": {
"build:css": "lessc src/less/app.less > dist/style.css"
},
"devDependencies": {
"less": "^3.0.0",
}
}
As a more comprehensive pattern for less in npm: You often need to also integrate less file dependencies. The package.json would look like this:
{
"name": "lesstest",
"description": "less test",
"scripts": {
"build:css": "lessc src/less/app.less > dist/style.css"
},
"devDependencies": {
"less": "^3.0.0",
},
"dependencies": {
"#foo/bar": "^1.0.0"
}
}
and in your local baz.less file you would refer to the dependency like this:
#import "#foo/bar/src/a-less-file";
#foo refers to the respective folder within your node_modules
folder and bar/src are the nested folders.
a-less-file refers
to a-less-file.less within your node_modules/#foo/bar/src

Pulling files from a directory into the root folder for NPM

I am publishing a library to NPM.
When I build the library, the resulting artifact is placed in the dist folder located in the root of my project as index.js.
When users install from NPM I would like index.js to be present in the root of the folder created in their node_modules folder. Presently, it remains in a directory named dist.
How can I do this?
My packages.json:
{
"name": "my-package",
"version": "0.0.9",
"files": ["dist/*"],
"main": "index.min.js",
"private": false,
"dependencies": {},
"devDependencies": {},
"repository": "git#github.com:username/my-package.git"
}
I had exactly the same problem.
I solved it not by copying the files up, but by copying the files I needed down into the ./dist/ folder and then doing an npm publish from there; NPM then treats that folder as a complete package and everything works very nicely. The only files I needed to copy from the root folder were:
package.json
README.md
Because we're going to copy these files down into the ./dist/ folder before we do the publish, we do NOT want the package.json file to reference ./dist/. So remove the package.json's files entry completely, because we don't need to tell it which files we'll take - we're going to take everything in the ./dist/ folder. I'm using TypeScript so I also have a typings entry, and again no reference to ./dist/.
{
"name": "my-package",
"version": "0.0.9",
"main": "index.min.js",
"typings": "index.d.ts",
"private": false,
"dependencies": {},
"devDependencies": {},
"repository": "git#github.com:username/my-package.git"
}
Now for the publish step. I built a gulp task that will perform the publish for me, making it nice and automated (except for incrementing the package version #).
From gulp I'll use Node's spawn() to kick-off the npm process. However, because I'm actually working on Windows I used "cross-spawn" rather than the normal built-in Node.js spawn (which I learned the hard way didn't work when I had spaces in my path!).
Here's my gulp file, with the TypeScript bits removed:
var gulp = require('gulp');
var del = require('del');
var spawn = require('cross-spawn'); // WAS: require('child_process').spawn;
var config = {
src: { tsFiles: './src/**/*.ts' },
out: { path: './dist/' }
}
gulp.task('clean', () => {
return del('dist/*');
});
gulp.task('build', ['clean'], () => {
....
});
gulp.task('publish', ['build'], (done) => {
// Copy the files we'll need to publish
// We just use built-in gulp commands to do the copy
gulp.src(['package.json', 'README.md']).pipe(gulp.dest(config.out.path));
// We'll start the npm process in the dist directory
var outPath = config.out.path.replace(/(\.)|(\/)/gm,'');
var distDir = __dirname + '\\' + outPath + '\\';
console.log("dist directory = " + distDir);
// Start the npm process
spawn('npm', ['publish'], { stdio:'inherit', cwd:distDir } )
.on('close', done)
.on('error', function(error) {
console.error(' Underlying spawn error: ' + error);
throw error;
});
});
Notice when we call spawn() we pass in a 3rd argument which is the options. The main entry here is the cwd:distDir, which tells spawn to run the npm process from the ./dist/ directory. Because using spawn can cause problems I've hooked into the spawn error handling. As I was troubleshooting my use of spawn() I found the following StackOverflow article very helpful.
This worked like a charm; my published package has all the files in the root directory and the ./dist/ folder is not published.

How to build Twitter Bootstrap 3 using Grunt

I've cloned Twitter Bootstrap 3 using git clone https://github.com/twbs/bootstrap.git:
Now, I am trying to build it using Grunt and I cannot find any documentation on how to do this.
Where should I start?
To add some more automation to your project, I would suggest you is to use Bower. This will even save you the time of downloading everything to your assets.
In order to use Bower you need bower.json
This file looks something like this:
{
"name": "WebExpressive",
"version": "0.0.0",
"authors": [
"username <username#abc.com>"
],
"description": "An awesome web application",
"license": "MIT",
"ignore": [],
"dependencies": {
"bootstrap": "latest",
"jQuery": "latest",
"angular-latest": "latest",
"turnjs": "latest"
}
}
Now you to plug your bower to grunt you need to have a Gruntfile.js which will look something like this
module.exports = function (grunt) {
//project configuration
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
shell: {
multiple: {
command: ['bower install',
'mv bower_components/** public/',
'rm -rf bower_components'].join('&&')
}
}
});
grunt.loadNpmTasks('grunt-shell');
//Default Tasks
grunt.registerTask('default', ['shell']);
//production Tasks
//grunt.registerTask('dist',[..]);
//test tasks
};
Now before you actually run the 'grunt', make sure that you got all npm packages in your project directory and package.json is in correct shape.
Take a look at my package.json file.
{
"name": "application-name",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node app.js"
},
"dependencies": {
"grunt": "*",
"grunt-shell": "*",
"grunt-contrib-uglify": "*",
"grunt-contrib-connect": "*",
"grunt-contrib-coffee": "*",
"grunt-contrib-compass": "*",
"grunt-open": "*",
"grunt-contrib-requirejs": "*",
"grunt-contrib-jade": "*",
"grunt-contrib-copy": "*",
"grunt-bower-install": "*"
}
}
Now you just need to run these commands and you can find the your bootstrap inside the public folder.
npm install
grunt
Please do visit grunt and grunt shell to explore more on this, they are just great.
For a basic instruction on how to build using Grunt you can refer to
http://getbootstrap.com/getting-started/
Essentially it's as easy as
grunt dist
If you are running from the command line in Windows, be sure to run cmd.exe as administrator.
