gulp-nodemon | gulp nodemon convenience | Code Analyzer library

I've attempted to update the gulpfile below to Gulp v4 from v3 but am still getting an error: AssertionError [ERR_ASSERTION]: Task never defined: client

Not sure what I am missing but realise that the functions may not be written correctly. The tasks in series are correct I believe: gulp.task('build', gulp.series('client', 'sass')); for example.

I come to you for help. I am using the gulp and browser-sync to automate my tasks: compiling sass, restarting the development server on every change, and checking the changes in the browser. I just want to make it faster. The problem is when I run gulp (I also use gulp-nodemon) it just runs nodemon but browser-sync doesn't run and the other tasks don't run either. If I run each task separately, they work, but all together by default with gulp, they don't work. If you want to help me, I will always appreciate it.

This is my code

I don't know much about React and I have to test an application made in React.

My problem comes when I try to run the server with gulp nodemon, and I get a lot of errors. Apparently the application is built on an old version of React and doesn't recognize some libraries or modules; I have already solved several of them regarding prototypes or the way a ReactClass is created, but I found one regarding Bootstrap that I haven't been able to solve.

This is the error I get:

Gulp should copy all sub-folders and files to the dist. But it copies only half of them, some folders will be ignored even if I change their names etc. (no special characters, same subfolder structure as the once that got copied correctly ...) - nothing worked. I just can't see any pattern in this.

There is no error message while running gulp. Nothing that would help me find the error.

This is my gulpfile.babel.js :

I am trying to set up a serve task that will do the following:

1. Call a watch task to watch for any source changes. ( the watch task calls a build task that builds the app into a "build" folder )
2. Start the app using Nodemon ( gulp-nodemon )
3. If a source change happens - rebuild the app and restart nodemon

So far I've written the following tasks:

I've tried to unsuccessfully run a node app, which runs fine on both High Sierra and Windows 10, but fails on Mojave 10.14.1. This is the error shown when running the gulp build_dev task:

This question has definitely been answered many times, but none of the solutions seem to work for me. I'm a beginner on Mongoose/Node and am following a PluralSight tutorial where I am getting the error in the title. It's specifically pointing to line 4 of bookModel.js. I have included both of my JavaScript files below as well as my package.json in case there's something about my package versions.

As far as I can tell, my code is identical to the tutorial and is very similar to virtually every solution I could find, but I'm still receiving the same error.

I apologize for the dumb question, but I've been struggling with this for a while and am dead in the water.

Thanks

I use gulp in my Node project and I was using gulp-nodemon for running nodemon within which in turn requires some dependencies which inturn requires dependencies and so on.

I was doing some security testing on my project using nsp and found out a vulnerability in my dependency brace-expansion and the resolution was to upgrade my package version to 1.1.7 or later: https://nodesecurity.io/advisories/338

The dependency tree is like this:

↳ gulp-nodemon 2.2.1 ↳ gulp 3.9.1 ↳ vinyl-fs 0.3.14 ↳ glob-stream 3.1.18 ↳ glob 4.5.3 ↳ minimatch 2.0.10 ↳ brace-expansion 1.1.6

So, how do I solve such problem cause, I guess I have to coordinate with all the people involved in the chain to fix this and some of them are inactive.

Is there any elegant way to fix these issues involved with chained dependencies?

I downloaded Typescript, Express, Sequelize, Postgres Example and run npm install and npm start.

On npm start it is producing some errors.
