When developing a project, the methods to correctly set the package name, description and author are as follows: 1. Set the name, description and author fields of package.json through npm init or yarn init in the Node.js project; 2. Use pyproject.toml or setup.py to configure name, description and authors; 3. The Rust project defines name (i.e. crate name), description and authors in Cargo.toml. Each language has different configuration formats but the purpose is the same. It must follow its own standard format and ensure complete and clear information.
When developing a project, specifying the package name, description, and authors is an important step in initializing the configuration. This information is usually written in the project's configuration file, such as package.json (Node.js project), Cargo.toml (Rust project), or pyproject.toml / setup.py (Python project). The following describes how to correctly fill in these fields according to different locales.
How to set it in a Node.js project
If you are creating a JavaScript or TypeScript Node.js project, you will usually use npm init or yarn init to generate package.json file. In this process you can directly enter:
- Package name : Usually a lowercase, spaceless name, such as
my-app - Description : In one sentence,
A simple CLI tool for data processing - Author : The format can be a name email, for example
John Doe <john></john>
You can also manually edit the package.json file, with the corresponding fields as follows:
{
"name": "my-app",
"description": "A simple CLI tool for data processing",
"author": "John Doe <john@example.com>"
}How to fill in Python projects
For Python projects, if you are using modern packaging tools such as poetry or setuptools , the relevant information will be written in pyproject.toml or setup.py .
Use pyproject.toml (recommended method)
[project]
name = "my-package"
description = "This is a sample Python package."
authors = [
{name="Jane Smith", email="jane.smith@example.com"}
] Use setup.py (old method)
from setuptools import setup
setup(
name='my-package',
description='This is a sample Python package.',
author='Jane Smith',
author_email='jane.smith@example.com',
)Configuration method in Rust project
If you are writing a Rust project, you mainly configure this information in the Cargo.toml file.
Open Cargo.toml and you will see something similar:
[package] name = "my-crate" version = "0.1.0" edition = "2021" # Description information description = "A small utility crate for string manipulation." # Author information authors = ["Alice Developer <alice@example.com>"]
Note that some projects may also use the [[authors]] field to define multiple authors, but it is more common to write only one name array.
Tips and precautions
- Try to maintain uniqueness in the package name to avoid conflicts with other projects.
- The description should be concise and clear, so that you can see the function of this package at a glance.
- The author’s information is recommended to add an email address to facilitate others to contact you.
- If multiple people maintain it, you can list multiple names in authors and the format is uniform.
Basically that's it. Different languages have slight differences, but the core fields are almost the same. The key is to write them correctly in the format.

What are some best practices for using Composer in production environments?
Jul 08, 2025 am 01:00 AM
When using Composer in a production environment, you need to pay attention to safety, stability and performance. 1. Use composerinstall-no-dev to reduce unnecessary development dependencies and reduce online environment risks; 2. Always submit and rely on composer.lock files to ensure version consistency, and avoid using updates during deployment; 3. Optional configuration platform-check=false ignores platform differences warnings, which is suitable for building packaging scenarios; 4. Enable APCU to accelerate automatic loading to improve performance, especially suitable for high concurrency services, while paying attention to namespace uniqueness to avoid cache conflicts.
How do I check if Composer is installed correctly?
Jul 07, 2025 am 12:12 AM
To check whether Composer is installed correctly, first run the composer--version command to view the version information. If the version number is displayed, it means that it is installed. Secondly, use the composerdiagnose command to detect configuration problems and ensure that the environment variables and permissions are normal. Finally, try to verify the functional integrity through the composerrequiremonolog/monolog installation package. If the vendor directory is successfully created and the dependency is downloaded, it means that Composer is fully available. If the above steps fail, you may need to check whether PHP has been installed globally or adjusted system path settings.
How do I install a Composer plugin?
Jul 09, 2025 am 12:01 AM
To install the Composer plug-in, please first confirm that Composer is installed and the composer.json file exists, and then follow the following steps: 1. Make sure that Composer has been installed and created composer.json; 2. Search and copy the required plug-in name on Packagist; 3. Use the composerrequirequire command to install the plug-in, such as composerrequiredealerdirect/phpcodesniffer-composer-installer; 4. Verify whether the plug-in is effective and check compatibility and configuration. Follow these steps to correctly install the Composer plug-in.
How do I configure Composer to use a specific PHP version?
Jul 03, 2025 am 12:07 AM
You can make Composer use a specific PHP version by specifying PHP binary files, using version management tools, or configuring composer.json. 1. In Unix-like systems, you can set an alias or export the COMPOSER_PHP environment variable to directly specify the PHP binary file; 2. Use tools such as phpenv or brew to switch the PHP version to achieve global or project-level version control; 3. Configure the platform.php field in composer.json to declare the PHP version required for the project to ensure that the dependency check is correct; 4. Windows users can call the specified PHP version by modifying the PATH environment variable or creating a batch script to call the specified PHP version.
How do I add a custom repository to my Composer configuration?
Jul 06, 2025 am 12:26 AM
To add a custom repository to the Composer configuration, edit the composer.json file in the project and specify the repository information under the "repositories" key. The specific steps are as follows: 1. Determine the repository type, such as VCS (Git, SVN, etc.), Composer, PEAR or Package; 2. Add the "repositories" block in composer.json and fill in the repository type and URL. For example, when using a VCS-type Git repository, the format is {"type":"vcs","url":"https

How do I use the --ignore-platform-reqs flag?
Jul 11, 2025 am 01:19 AM
When you encounter the "Yourplatformdoesnotatsatisfythatrequirement" error, you can use the --ignore-platform-reqs parameter to ignore the platform requirements for installation. The full name of this parameter is --ignore-platform-requirements. It is used to skip the PHP version, extension and other checks specified in composer.json when executing composerinstall or update. For example, if the current PHP version is 8.0 but the configuration requires 8.1, an error will be reported by default. If you add this parameter, the check will be skipped. Applicable scenarios include: 1. Local environment and true in containerized deployment or CI environment
How do I add a dependency to my composer.json file?
Jul 10, 2025 am 10:55 AM
To add dependencies to composer.json, the most common method is to use the composerrequire command, followed by manually editing the composer.json file. 1. Use composerrequiredor/package to automatically add the latest stable version dependencies and install them; 2. You can specify the version such as composerrequiredor/package: 1.2.3 or use the constraint character such as ^2.0; 3. This command will synchronize the update of composer.json and composer.lock and automatically handle the dependencies; 4. Manually edit suitable for batch addition or template projects, you need to maintain the version yourself and run c
