D.4 　参考资源

1. what is npm

-- To upgrade: run: [sudo] npm install npm@latest -g

2. Installing Node.js and updating npm

-- node -v to test. The version should be higher than v0.10.32

-- sudo npm install npm -g

-- npm -v to test. The version should be higher than 2.1.8

3. Fixing npm permissions

-- find the path to npm's directory: npm config get prefix

-- change owner: sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share} 

4. Installing npm packages locally

-- npm install <package_name>

-- ls node_modules

5. Using a package.json

-- To create package.json, run: npm init --yes

-- npm set init.author.email "wombat@npm.com" 

6. Updating local packages

-- npm update in the same directory as your package.json file

-- npm outdated to test

7. Uninstalling local packages

-- npm uninstall <package>

-- npm uninstall --save <package>

8. Installing npm packages locally

-- npm install -g <package_name>

-- sudo npm install -g <package>

9. Updating local packages

-- npm install -g <package>

-- npm outdated -g --depth=0 to find out which packages need to be updated

-- npm update -g to update all global packages

10. Uninstalling local packages

-- npm uninstall -g <package>

11. Creating Node.js module

author: Your Name <email@example.com> (http://example.com)

--Publish your package to npm

--Make a new directory outside of your project and cd into it

--Run npm install <package>

--Create a test.js file which requires the package and calls the method

--Run node test.js. The message should be output.

12. Publishing npm packages

--npm adduser/npm login to store the credentials on the client

--npm config ls

--npm publish. to check: https://npmjs.com/package/<package>

--npm version patch and npm publish to update package

13. Semantic versioning and npm

14. Working with scoped packages

-- @scope/project-name package's name begin with @, then it is a scoped package.

-- @username/project-name

--sudo npm install -g npm

--npm login

--npm init --scope=username package.json: {"name": "@username/project-name"}

--.npmrc npm config set scope username

--npm publish --access=public

--npm install @username/project-name --save

var projectName = require('@username/project-name')

15. Using dist-tags

--Tags are a supplement to semver for organizing and labeling different versions of packages.

--npm dist-tag add <pkg>@<version> [<tag>]

--npm publish --tag beta

--npm install somepkg@beta
