Is it possible to combine polymer.html, polymer-mini.html and polymer-micro.html into a single file using gulp or some means?
You can use vulcanize this is the official tool
https://github.com/polymer/vulcanize
install:
npm install -g vulcanize
use:
vulcanize target.html > build.html
you have also gulp-vulcanize.. that uses this tool.
it combine all the imports into one single file. it gives you some more options like remove docs and more.
if you want to combine only this 3 files you can create one html that import the 3 files and vulcanize this file.
Another tool that helps doing that is Polybuild (which utilizes Vulcanize)
An all-in-one build tool for Polymer apps
Polybuild combines vulcanize, crisper, and polyclean into one easy to use solution for optimizing Polymer applications for production.
Install
npm install -g polybuild
Use
polybuild index.html

I am new to SCSS. I love using SASS for my local development, but when I publish a client’s website and need to make a change, it’s a pain to have to dig out the old project and set everything up so I can edit locally and then publish those changes on the production site.
Currently, I make changes in the SCSS file and then I go to online SCSS to CSS converter tool and convert SCSS to CSS and then put that CSS into CSS file.
Is there any way that if I make a change in the SCSS file in the server then it should directly update the CSS file?
Currently, I use HTML, CSS, SCSS, and Javascript
Thanks,
Use sass package instead of VSCode Extensions like Live SASS Compiler.
Why should not we use "Live SASS Compiler" VSCode extension?
Live SASS Compiler extension is old and hasn't been updated for a while.
Some features like #debug, #warn, #error won't work, so if you are using it, you have to use the sass npm package for that.
So, How to install the sass package?
So simple, just run these commands.
npm install -g sass
And convert SASS to CSS automatically by running the below command on your terminal.
sass -w source/stylesheets/index.scss build/stylesheets/index.css
More information is available on the sass docs here

Make sure your project has a package.json file (and you have Node installed on your machine). Run npm init if you have Node but not package.json file, to initialize one.
Install sass package:
npm install sass --save-dev
Learn more about the package and its CLI
In the package.json file's scripts section, add these:
"scripts": {
"sass-dev": "sass --watch --update --style=expanded assets/css",
"sass-prod": "sass --no-source-map --style=compressed assets/css"
},
Run scripts:
npm run sass-dev
// or
npm run sass-prod
What is a source map? A particular file that allows the browser to map back from the processed, concatenated files to the original ones. It is helpful because we can see the original file names when we debug the CSS in the developer tools.
The above is a very basic setup to compiling SCSS files and "watching" them for changes. Your server should have a pipeline or some sort of build system that it would be able to run this npm command in order to compile SCSS files, so theoretically you don't need to push your pre-compiled CSS files to the server, but it does it by itself.
Can anyone point me to a tutorial that uses Polymer 2 and polymer-build from Polymer CLI? When I use any example in the polymer-starter-kit and use polymer serve, it works fine; but when I use polymer build and serve the bundled or unbundled directory, I get 404 errors. I have even updated to the newest alpha version of polymer-cli.
Also, using https://github.com/tony19/generator-polymer-init-2-x-app generators have the same problem.
I also spent quit a bit of time to figure this one out. Please use the polymer-cli#next instead of polymer-cli
Plain polymer-cli doesn't seem to have the latest build and optimizations to support Polymer 2.0#Preview related functionality.
You can install polymer-cli#next. In Ubuntu, you can simply use npm install -g polymer-cli#next
Then on, the bundled and unbundled versions of the application generated through polymer build would just works fine.
Edit:
You can find my sample Polymer2.0#Preview version of the code at https://github.com/phani1kumar/phani1kumar.github.io branch is "devmaster".
the sw-precache-config.js is initial render-blocking. This will load all the resources that the main page needs to make the app available for offline use. src/lazy-resources.html loads resources for the next routes.
You would need to get a proper configuration based on your layout and main page in the following 3 files:
sw-precache-config.js, polymer.json, src/lazy-resources.html. This is a practice followed in the shop app from Polymer team, you may opt to a different mechanism for lazy loading. The bottom-line for lazy loading is to load the resources after Polymer.RenderStatus.afterNextRender.

I noticed a bug in the generator in that the starter-kit subgenerator was missing a dependency on webcomponentsjs, which would cause an error with polymer-build. And as you discovered, polymer.json was also missing dependencies for the polyfill support of webcomponentsjs, which caused 404s on polyfilled browsers (such as Linux Chrome). That's all fixed now in v0.0.6.
You'll also need a version of polymer-build that does not try to uglify the JavaScript, which would fail due to its inability to recognize ES6. The new-build-flags branch of the polymer-cli repo replaces uglify with babili for ES6 minification (added in PR#525). You could check out that branch and build it yourself, or you could install it from here:
npm i -g tony19-contrib/polymer-cli#dist-new-build-flags
For convenience, this branch is added as a devDependency when generating the 2.0 starter kit with generator-polymer-init-2-x-app.
To build and serve a Polymer 2.0 Starter Kit project:
Generate a 2.0 Starter Kit (using generator-polymer-init-2-x-app, v0.0.6 or newer) by selecting 2-x-app - starter application template:
$ polymer init
? Which starter template would you like to use?
...
2-x-app - (2.0 preview) blank application template
2-x-app - (2.0 preview) blank element template
❯ 2-x-app - (2.0 preview) starter application template
After the project generator finishes, build the project with yarn build:
$ yarn build
info: Deleting build/ directory...
info: Generating build/ directory...
info: Build complete!
Note that the output is only build/, and no longer build/bundled/ and build/unbundled/.
Serve up the contents of the build directory, and automatically open a browser to it:
$ polymer serve build -o
You could also serve it with a different tool to verify that the build output would work outside of the context of any Polymer tools. Start a Python server in build/, and manually open a browser to it:
$ cd build
$ python -m SimpleHTTPServer
I am trying to use components from http://react-components.com (eg. react-youtube) in Reagent based application, but probably my naive approach is not the right one. I tried to install NPM packages with lein-npm module, include script in html page and use them via reagent/adapt-react-class as in this SO question. But for except this sample I wasn't successful.
Usually I get errors like "require/import/module is not defined" or "Youtube is undefined" (by having (def yt-test [] (r/adapt-react-class js/Youtube)). I am confused about what is needed to do. I read something about webpack/browserify, saw cljsjs packages - are those required in order to make this working?
I wrote a step by step guide on how to achieve this with webpack:
blob.tomerweller.com/reagent-import-react-components-from-npm
The general concept is the same as #scttnlsn suggested: bundle all npm packages in an external JS file and expose them through the global window object.
Those components are packaged as CommonJS modules. One approach for accessing CommonJS modules from ClojureScript is to bundle them into a single JavaScript file that can be included with your ClojureScript build.
You'll need to create a JavaScript entry point file which requires your various NPM dependencies and exposes them to ClojureScript (for example, by setting them on window). Create a file (let's call it index.js) containing:
window.YouTube = require('react-youtube');
Then use a tool like Browserify to bundle your entry point file and all of the dependencies it requires:
npm install -g browserify
browserify index.js --standalone window > bundle.js
Include bundle.js in your ClojureScript build and you'll be able to access the React component from ClojureScript via js/YouTube
My question is it good to install html5boilerplate with bower?
How can one proceed after that as it have its own directory for css and javascript and everything will come under bower_component/html5boilerplate
No, use Yeoman http://yeoman.io/ is even better than download the .zip
note: you need nodejs installed to install Yeoman
Install: npm install -g yo
https://github.com/h5bp/generator-h5bp
Install: npm install -g generator-h5bp
Run it with yo: yo h5bp
No, it's not.
HTML5 Boilerplate is meant to be used as a base for starting a new project.
Bower is a great way to manage libraries that are going to be used in a project, like jQuery or AngularJS.
The better thing for you to do is to download the HTML5 Boilerplate zip and extract its files into your project root folder.
I am currently creating a portable consolidation of my workflow using Node-Webkit which has node.js embedded. Now my problem is getting grunt/gulp inside the project itself as it depends on the cli somewhat(avoidable, granted), and also is confusing to me on the architecture. Is it possible to find just a .js with grunt in it to include much like Jquery/Handlebars?
Is this all I need to just include and run?
No before that make sure you environment is up, get the package.json, GruntFile.js file. In GruntFile.js you can specify what you want to pre-process. For example jade,Less,coffee. It looks very much like a node function, for sample you can refer to link
Now to make this work you also need to install various contrib plugins as per your requirement. Then register every single task in GruntFile.js. It really speeds up the development.
grunt.loadNpmTasks('grunt-contrib-less');
grunt.loadNpmTasks('grunt-contrib-jade');
grunt.loadNpmTasks('grunt-contrib-coffee');
grunt.registerTask('test', ['jade', 'less','coffee']);
So to process less,jade,coffee, we need to run the module installations such as
npm install grunt --save-dev
npm install grunt <module name> --save-dev
There are many more interesting configurations to learn and documentation is really nice, please refer to getting started guide
This adds the required Grunt and grunt plugins to package.json
