This article is to share with you about how to use vue-cli3.0.x. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Installation environment

Here, npm install-g @ vue/cli is recommended. Other settings need to be made through yarn global add @ vue/cli, and some files are generated and deleted for a few minutes.

Npm install-g @ vue/cli# oryarn global add @ vue/cli# uses the vue command to create a project (different from cli2.0 's init,create) vue create my-project

If you use yarn global add @ vue/cli to install, you need to go to the directory. Execution

The yarn / / installation project relies on cd packages/@vue/cli / / directory yarn link / / add link `vue` to perform instructions. Vue create my-project / / create a project.

Multi-environment configuration

Because the company has development environment, test environment, joint debugging environment, online environment. Reduce artificial configuration, one-time configuration to the principle. So in 2.0.x added "package.json" tt ":" node build/tt-build.js "" type configuration, configuration can not be a lot of files. The ".env" file configuration is supported in vue-cli 3.0.x, and I add ".env.development", ".env.production" and ".env.test" configurations here.

1. Basic correspondence and default

Development is used by vue-cli-service serve production is used by vue-cli-service build test is used by vue-cli-service test

two。 Specify configuration startup

To add other configurations, you need to specify the configuration below.

"dev-build": "vue-cli-service build-mode development"

3. Compilation of ".env" configuration file

The content of the configuration file is in the following format

VUE_APP_*

For example, ".env.production" is as follows

VUE_APP_MOCK_URL = 'https://xxx.xxx.xxx/restapi/'

4. Adjust the configuration of the environment

Console.log (process.env.VUE_APP_MOCK_URL); process.env.NODE_ENV / / specific BASE_URL / / vue.config.js configuration Thank you for reading!
