Vue:ProjectTemplate:Vue2 Babel ESLint TypeScript Router Vuex Sass Jest

vue-cli로 vue2+babel+eslint+typescript+vue-router+vuex+sass+jest 설치하는 방법에 대한 템플릿.

Command 

$ vue create .
? Please pick a preset: Manually select features
? Check the features needed for your project: Choose Vue version, Babel, TS, Router, Vuex, CSS Pre-processors, Linter, Unit
? Choose a version of Vue.js that you want to start the project with 2.x
? Use class-style component syntax? Yes
? Use Babel alongside TypeScript (required for modern mode, auto-detected polyfills, transpiling JSX)? Yes
? Use history mode for router? (Requires proper server setup for index fallback in production) No
? Pick a CSS pre-processor (PostCSS, Autoprefixer and CSS Modules are supported by default): Sass/SCSS (with node-sass)
? Pick a linter / formatter config: Prettier
? Pick additional lint features: Lint on save
? Pick a unit testing solution: Jest
? Where do you prefer placing config for Babel, ESLint, etc.? In package.json
? Save this as a preset for future projects? No

Unit Test 라이브러리는 Jest 를 설치한다.

그 박에 Mocha+Chai가 있지만 알아서 테스트해봐라.

vue2+babel+eslint+typescript+router+vuex+sass template 프로젝트와 비교하면 다음이 추가되었다.

  • devDependencies:
    • @types/jest
    • @vue/cli-plugin-unit-jest
  • eslintConfig.overrides 에 jest와 spec 관련 내용 추가.
  • jest.preset: @vue/cli-plugin-unit-jest/presets/typescript-and-babel

그리고 tsconfig.json 파일의 compilerOptions.types 배열에 "jest"가 추가되었다.

tests/unit/example.spec.ts file 

import { shallowMount } from "@vue/test-utils";
import HelloWorld from "@/components/HelloWorld.vue";

describe("HelloWorld.vue", () => {
  it("renders props.msg when passed", () => {
    const msg = "new message";
    const wrapper = shallowMount(HelloWorld, {
      propsData: { msg }
    });
    expect(wrapper.text()).toMatch(msg);
  });
});
