WeChat Mini Program CI

Automate WeChat Mini Program code upload, preview, npm build, and cloud deployments with CI/CD support using Node.js or CLI without opening DevTools.

miniprogram-ci

WeChat Mini Program CI tool · v2.1.31 · Node >= 16.1.0

A compilation module extracted from the WeChat Developer Tools for mini program/mini game projects. Supports both Node.js script calls and CLI commands.

Installation

npm install miniprogram-ci
# Global install (for CLI usage)
npm install -g miniprogram-ci

Prerequisites

1. Get AppID — appid of your mini program/mini game
2. Generate private key — WeChat Official Platform → Management → Development → Development Settings → Mini Program Code Upload → Generate "Upload Private Key" (.key file)
3. Configure IP whitelist (recommended) — Only whitelisted IPs can call upload/preview APIs
4. Key security — Private keys are not stored in plaintext on the platform. Must reset if lost.

Quick Start

const ci = require("miniprogram-ci");

(async () => {
  const project = new ci.Project({
    appid: "wx0000000000000000",
    type: "miniProgram",            // miniProgram | miniProgramPlugin | miniGame | miniGamePlugin
    projectPath: "./dist/build/mp-weixin",
    privateKeyPath: "./key/private.wx.xxxxx.key",
    ignores: ["node_modules/**/*"],
  });

  // Upload code
  const uploadResult = await ci.upload({
    project,
    version: "1.0.0",
    desc: "Fixed several issues",
    setting: { es6: true, minify: true },
    onProgressUpdate: console.log,
    robot: 1,
  });
  console.log("subPackageInfo:", uploadResult.subPackageInfo);

  // Preview (generate QR code)
  await ci.preview({
    project,
    desc: "Preview version",
    setting: { es6: true },
    qrcodeFormat: "image",          // image | base64 | terminal
    qrcodeOutputDest: "./preview.jpg",
    pagePath: "pages/index/index",
    searchQuery: "id=123",
    onProgressUpdate: console.log,
    robot: 1,
  });
})();

CLI Commands

# Upload
miniprogram-ci upload \
  --pp ./dist \
  --pkp ./key/private.key \
  --appid wx0000000000000000 \
  --uv 1.0.0 \
  --ud "Version description" \
  --r 1

# Preview
miniprogram-ci preview \
  --pp ./dist \

Proxy Configuration

Auto-detection order: HTTPS_PROXY → https_proxy → HTTP_PROXY → http_proxy → npm config → manual

ci.proxy("http://127.0.0.1:8888");   // manual
ci.proxy();                           // clear, restore auto

servicewechat.com is automatically added to no_proxy.

Return Values (upload/preview)

{
  subPackageInfo: [
    { name: "__FULL__", size: 123456 },    // entire package
    { name: "__APP__", size: 100000 },     // main package
    { name: "subPack1", size: 23456 },     // sub package
  ],
  pluginInfo: [
    { pluginProviderAppid: "wx...", version: "1.0.0", size: 12345 },
  ],
  devPluginId: "wx...",
}

Third-Party Platform

Supported since 1.0.28. Note:

• Project must have a valid ext.json
• Use the private key of the development mini program bound to the third-party platform
• IP whitelist also belongs to that development mini program
• The appid passed in must be the bound development mini program's appid

Robot Parameter

Specify which CI robot to use (1~30), enabling concurrent operations without conflicts.
