Output

NPM provides us with output that indicates whether a task has failed or succeeded. Understanding this output is key to finding mistakes in our code, so it$$s important to understand what npm is telling us$.$

The exit code of the task defines success or error. If the result of the script is $00$ then the task was completed successfully. Otherwise, npm will return an exit code of $11,$ indicating an error which can prevent the execution of next tasks.

Let$$s take a look at an npm task failure.

Run the following command in the terminal.

npm run style; echo $$?$

We expect this task to fail. Our output should look similar to the output below.

In this example, npm has returned an exit code of $11,$ indicating that the task has failed as well as additional information to locate the problem, such as:

Line Number & Position $15$:$13$

Error Message: error

Additional Information: Extra Semicolon

To fix more substantial errors, npm provides guidance on how to resolve them or where to look for help in its documentation guide. We$$re also provided with a debugging log$,$ npm$-$debug.log$,$ with more detailed information on the task error.

Once we have fixed all issues, npm will indicate success by returning an exit code of $00.$

By understanding npm outputs, we can accurately detect when errors occur and quickly resolve them to ensure that your tasks are properly automated.

NPM provides a wealth of information about its commands and how to use them, so make sure to check their documentation for any additional help or guidance needed.

Use the error feedback to get the npm run style command to run successfully.
