grunt-contrib-less | Compile LESS files to CSS | Plugin library

I use Vue/Typscript with webpack. And everytime i open page inject.preload.js throws an error like GET blob:http://URL/1fbc0606-8477-416b-a45f-50b4d824f2bb 0 () and i don't know where it comes from or why something got inject.

I tested it on Google Chrome Incognito mode and Firefox there is no error thrown.

How can i find out why this error occurs?

There are plenty of tutorials online for this, but after two days of struggle - I have to get some assistance. I am trying to to add a namespace to Bootstrap so I can use it in Salesforce without interfering with Salesforce's stylesheet. My goal is to wrap the bootstrap.less with .bs{} so I may refer to it on my page as a resource. It seems that no matter what, the bootstrap.css isn't compiling.

I'm trying to upload a file to a server on change using grunt-run and curl. I can get it to work if I hard code the file name into the actual task, but I'm trying to run it based on the file that changed...here's my grunt file so far (stripped down to the parts related to this question).

I've noticed that background: transparent is changed into background: 0 0; using less. I'm using grunt-contrib-less in 1.4.1 version that uses "less": "~2.7.1" to transform less to css. What these 0 0 in background are responsible for? Are there any treats resulting from using background: 0 0 instead of background: transparent? I tried to google this but i couldn't find anything that will explain me that

I have an application with SailsJs over NodeJs on Heroku and I can't run babeljs on. It runs ok on my localhost, but I always get the error:

Error: Couldn't find preset "env" relative to directory "/app"

The Heroku persists in look for itens at /app folder. This project does not have one /app folder

My app folders structure is:

Here what I am trying to do is , I am trying to write grunt in my command line and all it is does is , just watch the files. It does not start server. So what should I write to start server on localhost?

My grunt file is as shoen below:

Gruntfile.js

I have been trying to configure this gruntfile for days, I have seen and read multiple documents on how to set it up. I have been able to set it up so I can run individual tasks by typing in the individual commands into bash:

grunt uglify grunt sass grunt cssmin

However grunt watch seems to not watch any of my js files

All of which work fine, but when I tried to run them all under the "watch" task, my js files are all ignored. my command line just reads 'waiting...'. Changing any of the content in my js files does not trigger an update. I also had toruble running jshint as it kept telling me that it is looking for a string etc. so i disabled that plugin for now. Here is my file:

Lets say I have this:

I'm trying to use the grunt-browser-sync to watch the changes in the jsp and tag files, but the same is not working. Does anybody know what`s happening? Grunt works with tag and jsp files?
