npm 脚本，打包时将 package.json 复制到 dist

Question

I am trying to add a second part to my npm bundle script. The first part runs great, however I am trying to copy in 3 files along with the bundle.

So right now I have :

"bundle": "NODE_ENV=production webpack --output-file bundledFile.js && cp package.json dist/",

The NODE_ENV=production webpack --output-file bundledFile.js works great by itself. The part that is not working is the && cp package.json dist/ , I would like the script to copy my package.json (along with 2 other files actually, but just starting with this one) to the dist folder. Brand new to these scripts, any idea how to fix? Appreciate any advice, thanks!

Answer 1

The syntax should work (and seems to, looking at your comments). I would suggest splitting your npm scripts across multiple points, though:

{
  "bundle": "NODE_ENV=production webpack --output-file bundledFile.js",
  "copy": "cp package.json dist/ && cp README.md dist/ && cp .npmrc dist/",
  "build": "npm run bundle && npm run copy"
}

In order to be cross-platform compatible ( cp is not typically available on windows), I would also suggest adding a build file somewhere such as ./tools/copy-distrubution-files.js which would make use of fs to copy the necessary files , then call it in the npm scripts with node ./tools/copy-distribution-files.js . That will be (mostly) platform independent (you still have to assume that node is available as the nodejs executable, but that seems fairly reasonable to me).

If you're running on windows use the following command:

"copy": "copy \"package.json\" \"dist\" && copy \"README.md\" \"dist\" && copy \".npmrc\" \"dist\""

copy instead of cp. Don't forget to use "" for each path (escape them with \\ within the quoted command). and if you need to define a long path, don't use / (slashes) but \\ (backslashes)

like:

copy "devices\\VS-88UT\\index.html" "devices\\VS-88UT\\dist"

Also, if you prefere ther is a nice plugin to run bash command before and after each build

对我来说最快的方法是在 package.json 脚本中引用 powershell，如下所示：

"copyFile": "@powershell copy './source/package.json' './deploy'",

Answer 4

To copy folders and files in windows just use

xcopy git\\* dist\\ /e /i /h

I think this might help someone.
