vue のプロジェクトを自動生成するような何か。
こういう自動生成系は好かんのだがとりあえず乗っておく・・・
と思ったがちょっと見てみて、特にここから学ぶモノは無いと思った。
基本的な準備
$ mkdir hellocli $ cd hellocli $ ndenv loacl v11.1.0 $ ndenv rehash $ npm init $ npm install --save-dev vue-cli
入ったのは 2.9.6
コマンドを打つ。
$ npx vue init webpack hellocli ? Project name hellocli ? Project description A Vue.js project ? Author ? Vue build standalone ? Install vue-router? No ? Use ESLint to lint your code? No ? Set up unit tests No ? Setup e2e tests with Nightwatch? No ? Should we run `npm install` for you after the project has been created? (recom mended) npm
何かいろいろ聞かれるのだが、わかりやすさ重視で外す。
そうすると、hellocli というディレクトリが生成される。
中はこんな感じになっている
. ├── README.md ├── build │ ├── build.js │ ├── check-versions.js │ ├── logo.png │ ├── utils.js │ ├── vue-loader.conf.js │ ├── webpack.base.conf.js │ ├── webpack.dev.conf.js │ └── webpack.prod.conf.js ├── node_modules ├── config │ ├── dev.env.js │ ├── index.js │ └── prod.env.js ├── index.html ├── package-lock.json ├── package.json ├── src │ ├── App.vue │ ├── assets │ │ └── logo.png │ ├── components │ │ └── HelloWorld.vue │ └── main.js └── static
生成された過程の最後で
$ npm run dev
しろと出てくる。 これは package.json の spripts 項目の dev を実行する記述なので、中を見てみる。
中はこうなっている
{ "name": "hellocli", "version": "1.0.0", "description": "A Vue.js project", "author": "", "private": true, "scripts": { "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js", "start": "npm run dev", "build": "node build/build.js" }, "dependencies": { "vue": "^2.5.2" }, "devDependencies": { "autoprefixer": "^7.1.2", "babel-core": "^6.22.1", "babel-helper-vue-jsx-merge-props": "^2.0.3", "babel-loader": "^7.1.1", "babel-plugin-syntax-jsx": "^6.18.0", "babel-plugin-transform-runtime": "^6.22.0", "babel-plugin-transform-vue-jsx": "^3.5.0", "babel-preset-env": "^1.3.2", "babel-preset-stage-2": "^6.22.0", "chalk": "^2.0.1", "copy-webpack-plugin": "^4.0.1", "css-loader": "^0.28.0", "extract-text-webpack-plugin": "^3.0.0", "file-loader": "^1.1.4", "friendly-errors-webpack-plugin": "^1.6.1", "html-webpack-plugin": "^2.30.1", "node-notifier": "^5.1.2", "optimize-css-assets-webpack-plugin": "^3.2.0", "ora": "^1.2.0", "portfinder": "^1.0.13", "postcss-import": "^11.0.0", "postcss-loader": "^2.0.8", "postcss-url": "^7.2.1", "rimraf": "^2.6.0", "semver": "^5.3.0", "shelljs": "^0.7.6", "uglifyjs-webpack-plugin": "^1.1.1", "url-loader": "^0.5.8", "vue-loader": "^13.3.0", "vue-style-loader": "^3.0.1", "vue-template-compiler": "^2.5.2", "webpack": "^3.6.0", "webpack-bundle-analyzer": "^2.9.0", "webpack-dev-server": "^2.9.1", "webpack-merge": "^4.1.0" }, "engines": { "node": ">= 6.0.0", "npm": ">= 3.0.0" }, "browserslist": [ "> 1%", "last 2 versions", "not ie <= 8" ] }
つまりこうなる
webpack-dev-server --inline --progress --config build/webpack.dev.conf.js
こいつは何をやるかというと、ファイルを監視してビルドして、Node 内蔵の Webサーバを立ち上げるということをやる
ではそのビルドに使う設定はどれかというと build/webpack.dev.conf.js になる。 中身を見てみる。
