UniApp tips and practices for continuous integration and automated deployment

With the rapid development of mobile applications, the way we write and publish applications is also constantly evolving. Continuous Integration (CI) and Automated Deployment have become key tools for developers to improve efficiency and reduce the risk of errors. This article will introduce the techniques and practices of how to implement continuous integration and automated deployment in UniApp, and give corresponding code examples.

1. Configuring version control tools

The first step in continuous integration is to configure version control tools. Common choices include Git and SVN. Let's take Git as an example. First, install Git in the local environment and initialize a Git repository in the root directory of the UniApp project.

# 进入项目根目录
cd /path/to/your/uniapp/project

# 初始化Git仓库
git init

2. Writing automated build scripts

Automated build is a key step in achieving continuous integration. In UniApp, we can use npm scripts to write automated build scripts. First, create a package.json file in the project root directory and define the build script in it.

{
  "scripts": {
    "build": "uniapp-cli build",
    "lint": "uniapp-cli lint"
  }
}

In the above example, we defined two scripts: build is used to build the application, and lint is used to check code specifications.

3. Configuring continuous integration tools

Choose a suitable continuous integration tool. Common choices include Jenkins and Travis CI. In this article, we use Jenkins as an example to configure.

First, create a new project in Jenkins and select the "Free Style" project type. Configure the address and credential information of the Git warehouse in the "Source Code Management" option. Then, configure the build trigger to execute the build periodically or when a Git commit is triggered.

In the "Build Environment" option, configure the build command as npm run build, then save and trigger a build.

4. Configuring automated deployment

Automated deployment is a supplementary step to achieve continuous integration. In UniApp, we can use cloud native technology to achieve automated deployment. Taking uniCloud as an example, we can send the built application to the cloud for deployment.

First, install uniCloud’s CLI tool.

npm install -g @vdian/uni-cloud-deploy

Then, create a deploy.yaml file in the root directory of the UniApp project and configure the deployment information.

service:
  name: my-uniapp-service

functions:
  - name: my-uniapp-function
    description: My UniApp Function
    runtime: "Node.js 14"

triggers:
  - name: my-trigger
    description: My Trigger
    event:
      name: http
    triggerType: http
    methods: ["POST"]
    url: /my-function

In the above example, we defined a cloud function and configured an HTTP trigger. When the trigger receives a POST request, the corresponding cloud function will be called.

Finally, use the following command to deploy the application to the cloud.

uni-cloud-deploy deploy

5. Complete continuous integration and automated deployment

By configuring continuous integration tools and automated deployment tools, our UniApp project has achieved continuous integration and automated deployment. Now, whenever we submit code to the Git repository, Jenkins will automatically trigger the build and send the built application to the cloud for deployment. This way, we can iterate on our application quickly and efficiently.

To sum up, by configuring version control tools, writing automated build scripts, configuring continuous integration tools and automated deployment tools, we can achieve continuous integration and automated deployment in UniApp. This not only improves development efficiency but also reduces the risk of errors. I hope the introduction in this article will be helpful to everyone.

Code examples:

// App.vue
<template>
  <view class="container">
    <text class="text">Hello UniApp!</text>
  </view>
</template>

<style>
.container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}

.text {
  font-size: 28px;
}
</style>

<script>
export default {
  name: 'App',
}
</script>

The above are UniApp’s tips and practices for implementing continuous integration and automated deployment, and the corresponding code examples are attached. I hope it can be inspiring and helpful to everyone.
