javascript - Keystonejs:自定义 Keystonejs 默认管理界面主题

Question

我尝试自定义 Keystonejs Admin UI 主题:更改原色等。

所以我要覆盖位于 node_modules 中的 keystone.less:

.
|____node_modules
| |____keystone
| | |____public
| | | |____styles
| | | | |____keystone.less

|____public
| |____styles
| | |____keystone.less // This will overwrite the UI

新的 keystone.less 内容:

// Elemental
// ------------------------------

@import "@{elementalPath}/less/elemental.less";


// KEYSTONE VARIABLES
@import "../../node_modules/keystone/admin/public/styles/variables.less";

// KEYSTONE AUTH
@import "../../node_modules/keystone/admin/public/styles/auth.less";

// KEYSTONE SETUP
@import "../../node_modules/keystone/admin/public/styles/keystone/animation.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/base.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/dashboard.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/forms.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/navigation.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/tables.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/utils.less";

@import "../../node_modules/keystone/admin/public/styles/keystone/list.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/list-dropzone.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/item.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/toolbar.less";

// COMPONENTS
@import "../../node_modules/keystone/admin/public/styles/keystone/wysiwyg.less";
@import "../../node_modules/keystone/admin/public/styles/keystone/popout.less";


// REACT FIELDS
@import "../../node_modules/keystone/admin/public/styles/react/react.less";


@gray-base:              #000;
@gray-darker:            lighten(@gray-base, 13.5%); // #222
@gray-dark:              lighten(@gray-base, 20%);   // #333
@gray:                   lighten(@gray-base, 33.5%); // #555
@gray-light:             lighten(@gray-base, 46.7%); // #777
@gray-lighter:           lighten(@gray-base, 93.5%); // #eee

@brand-primary:         darken(#d326f6, 6.5%); // #337ab7
@brand-success:         #5cb85c;
@brand-info:            #d326f6;
@brand-warning:         #f0ad4e;
@brand-danger:          #d9534f;

@navbar-default-color:  green;

.primary-navbar {
  background-color: #d326f6;
  color: #d326f6;
  padding-bottom: .5em;
  padding-top: .5em;
}

我在 package.json 中添加了 less 依赖:

"less": "2.7.2"

如 doc 中所述:

如果您希望 Keystone 自动将 .less 文件编译为 .css 文件，请将此值设置为与静态选项相同的路径。 设置此选项后，对 .css 或 .min.css 文件的任何请求将首先检查同名的 .less 文件，如果找到，将生成 css 文件。

所以我在 keystone.init 中添加了选项:

'less': ['public', 'public-app'],

但是当我构建和部署应用程序时，我在 keystone.min.css

中看不到任何变化

样式没有变化。

我错过了什么？

对于我的解决方案，我执行了以下操作:

我添加了:可扩展的 theme.less 文件:

|____public
| |____styles
| | |____theme.less 

theme.less: 内容:

@import "../../node_modules/keystone/admin/public/styles/keystone.less";

@brand-primary:         darken(#d326f6, 6.5%); // #337ab7
@brand-success:         #5cb85c;
@brand-info:            #d326f6;
@brand-warning:         #f0ad4e;
@brand-danger:          #d9534f;

@link-color: #9c27b0;

.primary-navbar {
  background-color: #9c27b0;
  color: white;
  padding-bottom: .5em;
  padding-top: .5em;
}

在package.json中添加postinstall脚本:

"scripts": {
    "postinstall": "node scripts/admin-ui.js"
  } 

脚本会将 import theme.less 字符串添加到 node_modules/.../keystone.less

脚本内容:

const fs = require('fs');
const buff = fs.readFileSync('node_modules/keystone/admin/public/styles/keystone.less');
const content = buff.toString();

const styleLink = '@import "../../../../../public/styles/theme.less";';

if (content.includes(styleLink)) {
    return;
}

const newContent = content + '\n' + styleLink;
fs.writeFileSync('node_modules/keystone/admin/public/styles/keystone.less', newContent);

它将在每个 npm i

上自动执行

所以通过这种方式，样式将被覆盖。
