grunt-contrib-imagemin | Minify PNG , JPG , GIF and SVG images | Animation library

I have tried looking through all of the questions resolved by StackOverflow regarding people receiving this error:

Error: No default engine was specified and no extension was provided.

I feel like I have scoured every post on SO and none of the answers have corrected my code. There must be something else going on.

My issue that I am having is that I already created many html files before making a decision to use Node.js + Express for my back-end...so rather than worry about converting them all to a templating engine like pug or EJS, I just want to serve them from a static public folder in my directory.

From what I have researched, you do not need a templating engine to use Node.js + Express. But you do need to set up a static public folder to serve your files.

I have included the app.use(express.static(path.join(__dirname, 'public'))); in my app.js file. I have added a 'public' folder and put all of my static files inside of it, and in my routes file (my index.js file) I have written the following route:

router.get('/', (req, res) => { res.sendFile('./public/index.html'); });

I have tried changing it to the following:

1. res.sendFile('index');
2. res.sendFile(path.join(__dirname, 'index.html')
3. res.sendFile('../public/index.html');

I have also tried changing my static middleware syntax to just app.use(express.static('public')); and that didn't seem to change anything either.

All of these render the No default engine was specified and no extension was provided. error I provided above. I hate that I need to ask this questions when there are so many of the same questions on StackOverflow, but I am currently completely stumped at to what to do. Without further adieu, here is my code:

This is my file directory structure.

Here is my index.js file handling all my routes:

Looking for hours, still no luck.. Tried to run a very old Gruntfile (with imagemin and sass) which used to work. Imagemin is working, sass is not.

The error it throws is:

Could not find an option named "include-paths". Warning: Exited with error code 64 Use --force to continue. Aborted due to warnings.

I installed npm. I installed grunt-contrib-sass. I have sass & ruby installed.

where sass gives: C:\Users..\AppData\Roaming\npm\sass C:\Users..\AppData\Roaming\npm\sass.cmd

where ruby gives: C:\Ruby26-x64\bin\ruby.exe

This is a snippet of my Gruntfile, in case you need extra info, I will put it in completely:

After recent OS update to High Sierra. I am having problems with SASS and Grunt.

When I run grunt

I am attempting to use the grunt-concurrent task to run grunt-nodemon to watch my js scripts and concurrently use watchto still concat and uglify my files when they change as well.

When I run grunt on the command line I get the following infinite loop:

I am semi-new to Node.js and I'm having some confusion with connecting to my local host and interfacing with MongoDB. It seems as though it is ignoring my routes I have created.

First off, here is a snapshot of my directory structure.

Here is my package.json:

This is strange. Using this tutorial: https://ntdln.com/2017/07/25/using-javascript-modules/ I tried to do get the modules thing in JS. I run npm istall grunt-browserify --save-dev along with the other packages. My package.json file is

I was wanting to test out the imagemin-contrib in Grunt.js. I selected three jpg random images (sizes: 44kb, 92kb, 77kb, respectively) and set up the folder and plugin.

When I ran the imagemin grunt task, I received a message saying the photos were optimized successfully, but the numbers showed only a 5kb or 10kb reduction in size for the first two photos, and the third wasn't changed at all.

I was wondering if this was normal for an "optimized image"? I was expecting a more drastic drop in size. Could it be that the images I selected were simply already optimized? Or could it be in how I have written the grunt command?

Below is the code I used to execute the grunt command:

I'm not a pro with grunt but i have an angular js template that i want to use for my application i'm trying to make the browser open automaticaly when grunt is launched and reload page when html, js and css files are modified i added watch and livereload but it wont work is there something wrong in my code
