避免在Heroku上进行每次部署后的npm刷新 [英] Avoid npm refresh after every deployment on Heroku

问题描述

我有一个在Heroku上托管的Node.js网站，我使用git进行部署。
我使用几个节点模块，在package.json中引用;有没有一种方法可以防止Heroku每次部署新版本的代码时刷新它们，只要package.json没有改变？

注意：这对于编译需要一些时间的本地模块特别有用;对于.js-only模块，我成功地将它们从package.json中删除，并将它们的node_modules /文件夹添加到了git repo中。

我是官方Heroku Node.js Buildpack的维护者。

我们有一个beta版的buildpack新版本，它具有缓存支持功能，专为你上面描述的用例。您可以在 https：// github上阅读更多内容。 com / heroku / heroku-buildpack-nodejs / tree / diet＃关于此重构

最终，这将成为Heroku上的默认Node.js构建包，但是如果你想现在使用它，你需要显式地设置BUILPACK_URL config var：

  heroku config：set BUILDPACK_URL = https：//github.com/heroku/heroku-buildpack-nodejs#diet -a my-node-app 
 git commit -amfakeout--allow-empty 
 git push heroku 
  

I have a Node.js website hosted on Heroku, that I deploy with git. I use several node modules, referenced in package.json; is there a way to prevent Heroku to 'refresh' them each time I deploy a new version of the code, as long as package.json did not change?

Note: this would be especially useful for 'native' modules, whose compilation takes a bit of time; for .js-only modules, I was successful removing them from package.json, and adding their node_modules/ folder in the git repo.

解决方案

I'm the maintainer of the official Heroku Node.js Buildpack.

We have a new version of the buildpack in beta that features caching support, designed specifically for the use case you described above. You can read more about it at https://github.com/heroku/heroku-buildpack-nodejs/tree/diet#about-this-refactor

Eventually this will become the default Node.js buildpack on Heroku, but if you want to use it now you'll need to set the BUILPACK_URL config var explicitly:

heroku config:set BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-nodejs#diet -a my-node-app
git commit -am "fakeout" --allow-empty
git push heroku
