Nexus操作-Nexus下载前端npm依赖

• 此脚本是为了方便开发人员运维人员下载前端n p m依赖而编写使用，因为是自己在项目使用，所以分享出来
• 前端的依赖管理工具是npm的话，执行npm install命令，会在本地前端项目路径下生成package-lock.json文件，文件当中指定了前端项目所需要的各种依赖，以及对应依赖的约束版本
• 下载前端依赖就是基于package-lock.json当中的版本依赖路径决定。
• 前提条件
  • 需要前端开发人员提供package-lock.json
  • 运维人员下载依赖需要在互联网环境下，需要可以访问https://www.npmjs.com/package/vue
• 创建脚本为npm-download.sh，脚本内容如下：

#!/bin/bash
repolist=$(jq -r '.dependencies | keys[] as $k | "\(.[$k].resolved)"' < package-lock2024032000.json)
echo ${repolist} > aaa1230.txt

for package in $repolist; do
  array=$(echo "$package" | sed 's|/-/.*||')
  a2=${array##*//}
  arr=($(echo "$a2" | tr '/' ' '))

  for var in "${arr[@]}"; do
    if [ ${#arr[@]} -eq 3 ]; then
      PACKAGE_NAME="${arr[1]}/${arr[2]}"
      PACKAGE="${arr[2]}"
      echo $PACKAGE_NAME
      echo $PACKAGE
      # File containing version information (each line contains a version)

      REGISTRY_URL="https://registry.npmmirror.com"

      curl -s "${REGISTRY_URL}/${PACKAGE_NAME}/" | jq -r '.versions | keys_unsorted | .[]' > "$VERSION_FILE"

• 将提供的package-lock2024032000.json放到脚本同级目录下，执行sh npm-download.sh,会自动下载前端依赖到同级目录下
• 效果类似下图：

![image-20240323142328017]./images/image-20240323142328017.png)

• 本地执行脚本更新的依赖会放在/Users/houfei/anpm，每次执行玩脚本，直接打包/Users/houfei/anpm即可，
