Gulp is ensuring the destination file remains unchanged

I'm encountering an issue with gulp in my project. I've set up a process to automate the compilation of source and styles into a single file using gulp. However, I'm facing a problem where it doesn't want to overwrite the `application.js` file created from all `.js` files in my project. Interestingly, it does overwrite the compiled CSS files generated from all `.less` files in the project. Here is an overview of my project file structure:

.
├── gulpfile.js
└── apps
    ├── base
        ├── controllers
            ├── controllerBaseOne.js
            └── controllerBaseTwo.js
        ├── directives
            ├── directiveBaseOne.js
            └── directiveBaseTwo.js
        ├── services
            └── serviceBaseOne.js
        └── styles
            └── styleBase.less
        ├── header.html
        └── index.html
    ├── services
        ├── compilation
            ├── application.js
            └── application.css
        ├── controllers
            ├── controllerServicesOne.js
            ├── controllerServicesTwo.js
            └── controllerServicesThree.js
        ├── directives
            ├── directiveServicesOne.js
            ├── directiveServicesTwo.js
            └── directiveServicesThree.js
        ├── services
            ├── serviceServicesOne.js
            └── serviceServicesTwo.js
        └── styles
            ├── styleServicesOne.less
            ├── styleServicesTwo.less
            └── styleServicesThree.less
        ├── header.html
        └── index.html
    ├── appMain.js
    └── config.json

Below is how my current `gulpfile.js` is configured:

 
// Your unique configuration goes here...

In my `gulpfile.js`, the task `services-source` concatenates all `.js` files in the `apps` folder and sub-folders into a single file named `application.js` which is then placed in the `compilation` folder. Similarly, the `services-styles` task performs some less transformation on the styles before placing them in the same `compilation` folder. Minification of both sources and styles is also possible but disabled by default.

I attempted to resolve the overwriting issue by adding an `overwrite: true` parameter at the end of the `services-source` task for the destination of the compiled file, but it didn't seem to work. When running the `gulpfile.js`, the `application.js` file just keeps getting larger without overwriting. Any suggestions on what might be causing this problem?

Answer №1

It appears that your application.js file is getting included in your source every time you start the task.

To troubleshoot this issue, consider utilizing a tool like gulp-debug to log the current file in the stream for verification. You can refer to (this answer) for more information on how to do this.

If this indeed is the root of the problem, you may need to explicitly exclude it by modifying your sourcePaths array:

var sourcePaths = [
  "!path/to/application.js",
  basePath + "/**/*.js",
  webPath + "/**/*.js"
];

Answer №2

Give this a shot:

gulp.src("path/to/sourcefile") .pipe("path/to/destinationdir", { overwrite: false }))
