python项目中的javascript依赖项 [英] javascript dependencies in python project

问题描述

我正在编写允许人们将数学书籍发布为网站的软件。它主要基于Python + Flask，但是为​​了处理方程式，我使用了MathJax。 MathJax可以在客户端或服务器端使用（通过 MathJax节点）。在后一种情况下，我必须使用 npm 在我的主Python脚本可以访问的某个位置安装MathJax-node，然后从脚本中调用它。在前一种情况下，我必须提供MathJax.js作为资产，可供客户端使用（当前，我使用Flask的 send_from_directory 函数）。

I'm writing software that allows one to publish mathematical books as websites. It is based mostly on Python + Flask, but to deal with equations I'm using MathJax. MathJax can be used either client-side or server-side (through MathJax-node). In the latter case I have to use npm to install MathJax-node in some place accessible to my main Python script, then invoke it from the script. In the former case, I have to provide MathJax.js as an asset, available to client (currently I use Flask's send_from_directory function).

我的问题是：在Python中处理此类异构依赖关系的最佳实践是什么？我的目标是至少在类unix的系统（Linux或MacOS）上使安装过程尽可能简单，只要 node 和 npm 已经可用。

My question is: what is the best practice of dealing with such heterogenous dependencies in Python? My goal is to make installation process as simple as possible at least on unix-like systems (Linux or MacOS), provided that node and npm are already available.

我可以将我需要的所有javascript资源放入我的发行版本身，但是也许有更好的方法吗？ / p>

I can just put all the javascript sources I need into my distribution itself, but maybe there's a better way to do it?

在Node依赖的情况下，我将包含一个 package.json 文件，该文件指定所需的节点依赖性。对于其他语言/程序包管理器，我还将使用指定依赖项的常规方式（例如，为Ruby依赖项添加Gemfile）。

In the case of Node dependencies, I would include a package.json file in the directory which specifies the Node dependencies needed. For other languages/package managers, I would also use whatever the conventional way of specifying dependencies is (e.g. add a Gemfile for Ruby dependencies).

另一个常见的示例是Python / Flask附带使用 Bower 软件包管理器来获取静态前端依赖项。在这种情况下，依赖项在 bower.json 文件中指定，通常被拉入Flask的 static 目录。

Another common example of this that comes up with Python/Flask is using the Bower package manager for static frontend dependencies. In that case, the dependencies are specified in the bower.json file and are usually pulled into a bower folder in Flask's static directory.

一旦您有了 package.json 在指定的依赖项之后，您可以通过运行 npm install 来获取并安装所有所需的Node依赖项，在我看来，这比将javascript源包含在项目中是一个更优雅的解决方案。

Once you've got the package.json with the dependencies specified, you can fetch and install all the Node dependencies needed by running npm install which, in my opinion, is a more elegant solution than including the javascript sources with the project.

现在您已经拥有多个软件包管理器（例如，您可能使用 pip 作为Python依赖项。除了 npm 用于节点依赖项之外），您可能还想制作一个Makefile或一些部署/构建脚本来使用它们全部来获取/安装（例如，如果我使用Travis CI，我将更新 .travis.yml 调用 npm install 以及 pip install -r ）。

Now that you've got multiple package managers (e.g. maybe you're using pip for the Python dependencies in addition to npm for the Node dependencies), you might want to make a Makefile or some deployment/build script to fetch/install using all of them (for example, if I were using Travis CI, I would update my .travis.yml to call npm install in addition to pip install -r).
