# uni_modules

# 什么是 uni_modules

uni_modules is the plug-in modular specification of uni-app (supported by HBuilderRX 3.1.0+), which is usually the encapsulation of a group of js sdk, components, pages, uniCloud cloud functions, public modules, etc. It is used for embedding in uni-app projects, and also supports direct encapsulation as project templates.


Plug-in developers can write a uni_modules plug-in just like developing a uni-app project, and upload it directly to the plug-in market in HBuilderX.

Plug-in users can find the uni_modules plugin that meets their needs in Plugin Market, and use HBuilderX 3.1.0+ to directly import it into their uni-app project. You can also directly right-click in HBuilderX to upgrade the plug-in later.

Compared with ordinary plug-ins, the uni_modules plug-in has stronger independence and independent directory structure, and can be released, updated and uninstalled more conveniently (HBuilderX 3.1.0+ provides a right-click menu for the uni_modules plug-in, and supports publishing, updating, installation dependency, etc.)

Compared with node_modules (node.js module), the third party dependency of uni_modules defaults to the latest version during installation. Plug-ins are directly installed in the uni_modules directory without nesting. Of course, if developers want to fix a version of dependencies, they can include the third-party dependencies in their plug-in packages.

Why do we need to invent another uni_modules wheel after having node_modules?

  1. node_modules does not meet the needs of cloud integration. UniCloud's cloud functions, public modules, schema and various js_sdk, components, pages and projects in the front end cannot be effectively integrated in the node_modules mode.
  2. uni_modules is provided in the form of paid and commercial plug-ins, and the DCloud plug-in market provides copyright protection. But node_modules does not support payment and copyright protection.
  3. node_modules is a developer-friendly mode that affects the performance of end users. To save trouble, developers nested node_modules layer by layer, resulting in an astonishing number of files. uni_modules Module nesting is not supported, and developers are encouraged to optimize package’s size
  4. uni_modules encourages developers to always use the latest version. And tools for version content comparison are provided in HBuilderX
  5. node_modules placing is also supported in uni_modules, without forced rejection.


  1. 支持在HBuilderX里直接发布、更新、删除。而无需在web界面操作。
  2. Support dependencies (configured in package.json)
  3. If the location of the plug-in file is uniform, it will not cause the problem of downloading a plug-in but not knowing how many files are written to the number of directories under the project. When deleting the plug-in, you can delete it with one click


# Directory structure

# uni_modules for project plugins

If the uni_modules plugin is a project type plugin, you only need to put a package.json that conforms to the uni_modules specification in the root directory of the project.

Right-click on the package.json to update the project plugin or publish it to the plugin marketplace.

For example uni-admin, uni-starter , can be updated in this way.

# uni_modules for non-project plugins

If it is a plug-in of non-project type, such as component, js sdk, page template and cloud function, it needs to be placed in the uni_modules directory of the project.

At this time, the directory structure under the uni_modules directory is the same as the project structure of uni-app, as follows:

uni_modules                                项目根目录下
└── [plugin_id] // 插件 ID
    ├── uniCloud                           插件内的uniCloud内容会被虚拟合并到项目根目录的uniCloud中(注意:插件内的uniCloud目录,没有-aliyun,-tcb后缀)
    ├── components                         符合vue组件规范的uni-app组件目录,支持easycom规范
    ├── utssdk                             存放uts插件
    ├── hybrid                             存放本地网页的目录,详见
    ├── pages                              业务页面文件存放的目录 
    ├── static                             存放应用引用静态资源(如图片、视频等)的目录,注意:静态资源只能存放于此
    ├── wxcomponents                       存放小程序组件的目录,详见
    ├── license.md                         插件使用协议说明
    ├── package.json                       插件配置,必选(除此之外均`可选`)                          
    ├── readme.md                          插件文档
    ├── changelog.md                       插件更新日志
    ├── menu.json                          如果是uniCloud admin插件,可以通过menu.json注册动态菜单,详见 menu.json 配置

That is, the uni_modules directory is equivalent to duplicating the project structure of uni-app.


  • Files of pages.json, App.vue, main.js, manifest.json and uni.scss are not supported in the plug-in directory. If plug-in users need to modify the contents of these files, please elaborate in detail in the plug-in document (readme.md).
  • The plugin directory supports pages_init.json, which can easily register pages to the project's pages.json, see below
  • When referencing resources or jumping pages inside plug-ins, please use relative paths as much as possible.
  • The components directory in the plug-in also supports easycom specification. Plugin users can directly use the components meeting the easycom specification in the plug-in in the project. When there is an easycom component conflict in the project or plug-in, a prompt will be given during compilation and you can resolve the conflict by modifying the component directory and component file name.

In HBuilderX, if uni_modules contains the contents of the uniCloud directory, it will be displayed in uniCloud in the root directory of the main project by way of reference. A shortcut arrow will appear in the lower left corner of the icon in front of the file.

As shown in the figure below, there is a uni_modules named uni-config-center in the project, which contains a public module named uni-config-center. Therefore, under the common module directory common in the project root directory, there will also be an additional uni-config-center.

Opening a file indicated by a reference icon in HBuilderX will open the original address.

# Use uni_modules plug-in

# uni_modules.config.json

uni_modules.config.json In the root directory of the project, you can configure the trigger script updated by the plug-in (usually used to perform customized automation tasks) and the service space supported by the plug-in uniCloud. The following is a detailed configuration description of uni_modules.config.json

	"scripts": {
		"postupdate": "node scripts/upgrade.js", // 更新插件后执行该脚本,可从process.env.UNI_MODULES_ID获取当前被更新的插件ID,如果存在多个,以,隔开
		"preupload": "node scripts/preupload.js", // 上传插件之前执行该脚本,可从process.env.UNI_MODULES_ID获取当前被更新的插件ID,如果存在多个,以,隔开
		"postupload": "node scripts/postupload.js" // 上传插件之后(无论上传成功还是失败)执行该脚本,可从process.env.UNI_MODULES_ID获取当前被更新的插件ID,如果存在多个,以,隔开
	"uni_modules": {
		"uni-id": { // 插件ID
			"uniCloud": ["aliyun", "tcb"] // 当项目同时存在aliyun,tcb时可手动指定该插件所属的服务空间


  • When only one service space is associated with the project, the uniCloud-related resources in the uni_modules plugin will be automatically attributed to this service space, so there is no need to configure the service space to which uniCloud belongs in uni_modules.config.json
  • When there are two service spaces in the project (Alibaba Cloud and Tencent Cloud exist at the same time)
    • If the platform is not configured in uni_modules.config.json, then when uploading the uniCloud resources of this plug-in, you will be prompted to select which service space to upload to
    • If the platform has been configured in uni_modules.config.json, the configuration will prevail when uploading and it will be automatically attributed to the specified service space

# npmignore

When uni_modules plug-in is released to plug-in market, it is usually necessary to ignore some directories or files, such as unpackage, .hbuilderx, node_modules and so on, then the file can be ignored by npmignore file.

File name: .npmignore. Note that there is a dot at the beginning. Contents of a typical npmignore file are as follows:



  • The .npmignore in the project root directory is effective for publishing projects and plug-in templates. uni_modules/Plug-in Id/.npmignore Effective for published plug-ins

# pages_init page registration

Added in HBuilderX 3.5.0+

In the past, when plugin authors provided page class plugins, they needed to manually inform users in the documentation which pages to register in pages.json. like:

    "path":"uni_modules/xx-yy/pages/demo/demo" // 按插件所在目录引入对应的页面

pages_init.json solves this annoyance.

When the pages_init.json file exists in the root directory of the uni_modules plugin, when the plugin imports the project, a pages.json modification interface for merging page routes will pop up. Plug-in users click the Confirm button to complete the registration of the plug-in page to the project pages.json.

Example plugin: Problem Feedback Page Admin Template

The sample code is as follows:

    "pages": [{
            "path": "uni_modules/uni-feedback-admin/pages/uni-feedback-admin/add",
            "style": {
                "navigationBarTitleText": "新增"
            "path": "uni_modules/uni-feedback-admin/pages/uni-feedback-admin/edit",
            "style": {
                "navigationBarTitleText": "编辑"
            "path": "uni_modules/uni-feedback-admin/pages/uni-feedback-admin/list",
            "style": {
                "navigationBarTitleText": "列表"

Complete pages parameters details view


  • The pages_init.json file will not eventually be imported into the project.
  • pages_init.json does not support annotations (including: conditional compilation).
  • If the HBuilderX version is lower than 3.5, or the plugin author does not provide pages_init.json, you still need to manually edit the pages.json registration page.

# Develop uni_modules plug-in

# Create new uni_modules directory

In the root directory of the uni-app project, create the uni_modules directory, and you can click Create uni_modules directory on the right-click menu of the project.


  • In case of vue-cli project, the uni_modules directory is located under src, which is src/uni_modules

# Create uni_modules plug-in

  1. Right-click the uni_modules directory in HBuilderX Create uni_modules plug-in

  1. Fill in the correct plug-in ID and select the plug-in classification

Plugin ID naming specification:

  • In the format of: 'Author ID - English name of plug-in'. For example, xx-yy, where the author ID and English name of plug-in can only contain English and numbers
  • Author ID is defined by the plug-in author, and cannot use 'DCloud', 'uni' and other keywords. Its length is required at least 2 characters
  • The plug-in name should visually express the function of the plug-in. For example: tag, button, etc.


  • The uni_modules plug-in can be configured with three-party dependencies in the uni_modules->dependencies node of package.json (the dependent plug-in must also be the uni_modules plug-in). If it is an npm plug-in that relies on three parties, you can use the standard dependencies node configuration.
// 通过 uni_modules->dependencies 配置三方uni_modules插件依赖
  "id": "uni-badge",
  "displayName": "uni-badge 数字角标",
  "version": "1.2.2",
  "description": "数字角标(徽章)组件,在元素周围展示消息提醒,一般用于列表、九宫格、按钮等地方。",
  "uni_modules": {
    "dependencies": ["uni-scss"]

# Release to plug-in market

When your plug-in is developed, you can publish it directly to the plug-in market for free or paid use by others. The plug-in market provides mechanisms such as realization and evaluation. Excellent plug-in authors can earn tens of thousands of dollars a month.

Release process:

  1. 在HBuilderX中插件目录右键点击发布到插件市场
  2. 填写插件信息 Tips
  • If you need to release it as a project template, please create package.json in the root directory of the project, and then right-click the menu to release to the plug-in market.
  • When releasing the plug-ins, you can choose to upload the current project as an example project. A complete example project helps users get started quickly.

# Modify plug-in basic information

When your plug-in is released to the plug-in market, if you need to adjust some basic information in the plug-in market, such as Chinese name, description, keywords, and readme.md, you can right-click the Modify the plug-in basic information directly in the plug-in directory.

  • The update log filled in the releasing window will automatically be synchronized with changelog.md in the root directory

# Guide to migrating existing plugins to uni_modules plug-ins

  1. Migrate the plug-in content to the directory named after the plug-in ID under the root directory of your uni-app sample project uni_modules. For example, if your existing plug-in ID is xx-yy, the directory structure is: uni_modules/xx-yy
  2. Run your own sample project to verify that if all functions are normal after the plug-in migrates to the directory
  • When migrating directories, you will usually encounter problems with resource reference paths. So all path references should be modified as relative paths as much as possible.
  • If the plug-in has a cloud function or database of uniCloud, please note that uniCloud in the plug-in directory cannot have suffixes of the vendor when migrating. You can specify the cloud service provider supported by the plug-in when releasing the plug-in.
  • Files of pages.json, App.vue, main.js, manifest.json and uni.scss are not supported in the plug-in directory. If plug-in users need to modify the contents of these files, please elaborate in detail in the plug-in document (readme.md).
  1. When all the functions of the migrated plug-ins are normal, you can release a new version of the plug-in that supports uni_modules to the plug-in market (the plug-in market will keep your last version of the non-uni_modules plug-in at the same time)
  • Create package.json in the root directory of plug-in, you can simply fill in one plug-in ID temporarily, and fill in other information through the release window (it will be automatically synchronized back to package.json)
  • Plug-in document, migrate to readme.md in the root directory of plug-in
  • Right-click package.json and click Release to plug-in market, select the classification, and fill in the plug-in information (consistent with the existing information in the plug-in market as much as possible)
  • 发布成功后,您可以在插件市场的插件详情页右侧,查看到您的插件已同时提供了uni_modules版本和非uni_modules版本(仅保留最后一个非uni_modules版本)
