vue-cli operates Webpack environment configuration
This time I will bring you vue-cli operation Webpack environment configuration, vue-cli operation Webpack environment configuration What are the precautions, the following are Let’s take a look at practical cases.
The reason why Vue is so popular now is partly due to the official scaffolding generation tool Vue-cli, which greatly simplifies the cost of setting up an environment for beginners. However, in actual business we often need to implement other functions To transform webpack, this article will first learn the template generated by vue-cli based on some actual business needs, and then make relevant modifications.
Vue-cli generated template file directory
├── README.md ├── build │ ├── build.js │ ├── check-versions.js │ ├── dev-client.js │ ├── dev-server.js │ ├── utils.js │ ├── webpack.base.conf.js │ ├── webpack.dev.conf.js │ └── webpack.prod.conf.js ├── config │ ├── dev.env.js │ ├── index.js │ └── prod.env.js ├── index.html ├── package.json ├── src │ ├── App.vue │ ├── assets │ │ └── logo.png │ ├── components │ │ └── Hello.vue │ └── main.js └── static
The main focus of this article is
build - the code to compile the task
config - webpack's configuration file
package.json - Basic information about the project
The specific meaning of each line of webpack configuration will not be introduced in detail here. Please refer to the webpack configuration file analysis of vue2.0 scaffolding
Common requirement 1: Multi-environment configuration and release
The template generated by Vue-cli is only configured with npm run dev and npm run build scripts to start the development environment service and execute packaging respectively. Often, a normal company development process will have at least development, test simulation, and production environments. The server request address or some configuration parameters responded to by each environment will be different, and when publishing, it needs to be published to multiple servers, so it needs to be executed. Automated scripts. Build and release.
We must first clarify this issue and reprint an article, author: Zheng Haibo, link, source: Zhihu
This actually has nothing to do with vue, it is a general question: where the code is built. If the question's server refers to a running server, then neither option is actually a good choice. Many newcomers, including me, thought the deployment code looked like this before I started working.
But in fact, it will be more troublesome in larger Internet companies. The following introductions are common practices and some simplified processes are just for the convenience of newcomers to understand. Submit the code to the git or svn server. Note that this is the source file, not the built file.
The build server will pull the code version to be released from the git server and complete it here.InstallationDependencies, Such as the title of vue. And build files for deployment. These files are generally compressed into a compressed package for management
The built release package will be uploaded to the transfer station: File Management Server Cluster
The actual running server is generally not a single server, but a cluster. These n servers will pull the same compressed package of the corresponding version from the file server, decompress it and finally run it
In fact, there are obvious sequential processes here, which would be very troublesome if done manually. Therefore, generally large companies will have an automatic deployment platform to coordinate and complete these tasks. As a developer, you only need to click "One-click deployment" will complete the above content
For example, when cooperating with webhooks provided by gitlab and github, they automatically notify the automatic deployment platform that the stable version of the code has been pushed (Push Event). Then we don’t even need to click the button. This is a typical case of separation of build and deployment, which brings many benefits, such as ensuring that a copy of the code is built, and avoiding the possibility of inconsistencies caused by multi-environment builds. Building is generally a high-overhead behavior, which may Instabilities that cause instability in the running server can be quickly rolled back or restored, and the same version of the code does not need to be rebuilt. . .
Having said so much, packaging and building is not a simple matter, so automated tools are needed to configure it. The existing mature solution is to use docker to build an application container engine to build, publish, etc. However, I am not familiar with this area. Some students who are familiar with it can share it.
I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!

How to configure nginx to ensure that the frps server and web share port 80
Jun 03, 2023 am 08:19 AM
First of all, you will have a doubt, what is frp? Simply put, frp is an intranet penetration tool. After configuring the client, you can access the intranet through the server. Now my server has used nginx as the website, and there is only one port 80. So what should I do if the FRP server also wants to use port 80? After querying, this can be achieved by using nginx's reverse proxy. To add: frps is the server, frpc is the client. Step 1: Modify the nginx.conf configuration file in the server and add the following parameters to http{} in nginx.conf, server{listen80
Real-time protection against face-blocking barrages on the web (based on machine learning)
Jun 10, 2023 pm 01:03 PM
Face-blocking barrage means that a large number of barrages float by without blocking the person in the video, making it look like they are floating from behind the person. Machine learning has been popular for several years, but many people don’t know that these capabilities can also be run in browsers. This article introduces the practical optimization process in video barrages. At the end of the article, it lists some applicable scenarios for this solution, hoping to open it up. Some ideas. mediapipeDemo (https://google.github.io/mediapipe/) demonstrates the mainstream implementation principle of face-blocking barrage on-demand up upload. The server background calculation extracts the portrait area in the video screen, and converts it into svg storage while the client plays the video. Download svg from the server and combine it with barrage, portrait
