【モダンJavaScript】npm scriptsで簡単にコマンド実行！

📝 概要
今回はnpm scriptsに関する入門講座です。node_modules内の実行ファイルを毎回指定するのは大変で、しかもチーム開発の際も分かりにくいかと思うので、そういったコマンド（タスク）の実行は基本的にはnpm scriptsに登録して使います。昔はGulpやGruntといったタスクランナーで行っていましたが、今はnpm scriptsだけで行うのが一般的になってきましたね！

NPM Install and NPM CI: In What Aspect They Differ

Nodejs web development has achieved such a huge acclamation all over the world just because of its large ecosystem of libraries known as NPM modules. It is the largest software package library in the world, with over 500,000+ packages. Each time a Command Line Interface (CLI) for npm comes as an add-on with Nodejs installation which allows developers to connect with packages locally on their machine.

The idea of npm modules had come with some technical advancement in package management like reusable components, with easy installation via an online repository, with version and dependency management.

In general,NPM is a default package manager for every Nodejs development project. Npm eases the installing and updating dependencies processes. A dependency list on npmjs even provides you with the installation command, so that you can simply copy and paste in the terminal to initiate installation procedures.

All npm users have an advantage of a new install command called “npm ci(i.e. npm continuous integration)”. These commands provide enormous improvements to both the performance and reliability of default builds for continuous integration processes. In turn, it enables a consistent and fast experience for developers using continuous integration in their workflow.

In npm install, it reads the package.json to generate a list of dependencies and uses package-lock.json to know the exact version of these dependencies to install. If the dependency is found in package-lock.jso, it will be added by npm install.

Whereas here, the npm ci (continuous integration) installs dependencies from package-lock.json directly and use up package.json just to verify that there are no mismatched versions exists. If any dependencies mismatching versions, it will show an error.
