在构建期间通过钩子编辑值 [英] Editing values during build via hooks

问题描述

我在构建应用程序时尝试编辑版本变量，但我根本无法使用 cordova 挂钩运行任何脚本.

Im trying to edit a version variable when I build my applications, but I can't get any scripts to run using the cordova hooks at all.

我想从 package.json 和 git 提交的最后 5 位获取版本，这样我就可以使用 1.0.0.89gkt 作为我的版本.

I want to get the version from the package.json and the last 5 digits of the git commit so i can have something like 1.0.0.89gkt as my versions.

在过去使用 ionic 1 并使用 grunt 或 gulp 时，我能够轻松地将脚本添加到构建过程中.

In the past for ionic 1 and using grunt or gulp I was able to add the scripts into the build process easily.

我已经尝试了使用 hooks/hook_name/script 格式和在 config.xml 中使用 hook 标记的旧方法，但对我都不起作用.

I've tried both the old way using the hooks/hook_name/script format and using the hook tag in the config.xml and neither work for me.

通过 package.json 覆盖离子脚本允许我更改自动运行的脚本，但如果可以的话，我想避免这种情况.虽然我可以轻松地将我的文本替换添加到一个复制脚本或其他东西(我需要找出哪个最好)

Overwriting the ionic scripts via the package.json allows me to change the scripts that are automatically run, but I want to avoid that if I can. Though I can easily add my text replace to one of the copy scripts or something (ill need to work out which one is best)

如果有人知道更好的方法或钩子无法触发的原因，请告诉我.

If someone knows a better way or a reason as to why the hooks wont fire, please let me know.

推荐答案

这是我最终使用的解决方案.

This is the solution that I ended up using.

脚本/before_prepare_increment_build_number.js

scripts/before_prepare_increment_build_number.js

var fs = require('fs');
var git = require('git-rev-sync')

console.log('Incrementing Build Number');


var file = fs.readFileSync('www/build/main.js', 'utf8');

var str = git.short();

console.log('short', str)

var result = file.replace(/{{GITVERSIONSTRING}}/g, str);

fs.writeFileSync('www/build/main.js', result);

console.log('Incrementing Build Number Completed');

config.xml

<hook src="scripts/before_prepare_increment_build_number.js" type="before_prepare"/>

我需要确保一切同步发生，否则内置脚本会在字符串被替换之前开始复制.

I needed to ensure that everything was happening synchronously otherwise the built in scripts would start copying before the strings had been replaced.

目前它的目标是由默认 ionic-app-scripts 生成的整个 main.js，因此可以根据需要添加所有比较和替换.此解决方案使用内置的 cordova 钩子 before_prepare

Currently its targeting the whole main.js that is generated by the default ionic-app-scripts so all comparisons and replacements can be added as required. This solution uses the built in cordova hook before_prepare

另一个提高效率的解决方案是根据需要定位单个文件，并在 package.json 中的构建/服务脚本之前添加脚本，并让 npm 控制和管理它.

Another solution that can be used to make it a bit more efficient is targeting the individual files as required and adding the script before the build/serve scripts in the package.json and have npm control and manage it.

在您的 package.json 中，您可以将脚本添加到准备钩子中.

Inside your package.json you could add a script to a prepare hook.

"scripts": {
    "prepare": "node increment_build_number.js",
}
