npm-run-alldisplays output from all scripts it runs, but it doesn’t provide real-time output for parallel scripts by default. You can configure it to improve output clarity. - concurrently:
concurrentlyprovides real-time output from all running commands, making it easy to monitor their progress. You can customize how the output is displayed to differentiate between commands. - np:
npprovides output related to the publishing process, including version changes, changelog updates, and any errors that occur during publishing. It’s focused and informative but not real-time. - npm-run:
npm-runsimply outputs the result of the npm script it runs. It doesn’t provide any special output management or formatting.
Error Handling

npm-run-allcan be configured to stop on errors, and it provides clear error messages for failed scripts. It’s more flexible than the others in handling errors. - concurrently:
concurrentlyhandles errors from all running commands and can be configured to stop all commands if one fails. It provides clear error messages to help diagnose issues. - np:
nphas robust error handling for the publishing process, including checks for git status, versioning, and npm login. It prevents publishing if there are issues, ensuring a smooth process. - npm-run:
npm-runrelies on the error handling of the npm scripts it runs. It doesn’t provide any additional error handling or reporting.
Customization
- npm-run-all:
npm-run-allis highly customizable, allowing you to define how scripts are run (parallel vs. sequential), set prefixes, and configure error handling. - concurrently:
concurrentlyallows for some customization, such as changing the output style, setting command prefixes, and configuring how it handles errors and exits. - np:
npoffers limited customization, mainly around the publishing process. You can configure prompts, git settings, and npm settings, but it’s mostly opinionated to ensure best practices. - npm-run:
npm-runis a simple tool with minimal customization options. It runs scripts as defined in the package.json file without any additional features.
