Visual
VS 使用 NPM
可以直接添加 NPM 配置文件:右键项目添加 - 新建项 - 搜索 npm。
然后直接编辑 NPM 配置文件(pacakge.json)并保存,VS 就会自动添加包。
自动创建的 node_modules 文件夹默认不被伺服,可以通过修改 Startup 手动将其伺服。
app.UseStaticFiles(new StaticFileOptions
{
RequestPath = "/node_modules",
FileProvider = new PhysicalFileProvider(Path.Combine(env.ContentRootPath, "node_modules"))
});

前端验证
通过 jquery + jquery-validation + jquery-validation-unobtrusive 实现前端验证。
{
"version": "1.0.0",
"name": "tutorial",
"private": true,
"devDependencies": {},
"dependencies": {
"bootstrap": "4.3.1",
"jquery": "3.3.1",
"jquery-validation": "1.19.0",
"jquery-validation-unobtrusive": "3.2.11"
}
}
CDN 与 asp-fallback
通过 asp-fallback-src 和 asp-fallback-test 实现回落机制,当测试发现 CDN 的 js 无法使用时,切换为本地 js。
<environment include="Development">
<script src="~/node_modules/jquery/dist/jquery.js"></script>
<script src="~/node_modules/jquery-validation/dist/jquery.validate.js"></script>
<script src="~/node_modules/jquery-validation-unobtrusive/dist/jquery.validate.unobtrusive.js"></script>
</environment>
<environment exclude="Development">
<script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.js"
asp-fallback-src="~/node_modules/jquery/dist/jquery.js"
asp-fallback-test="window.jQuery"></script>
<script src="https://cdn.bootcss.com/jquery-validate/1.19.0/jquery.validate.js"
asp-fallback-src="~/node_modules/jquery-validation/dist/jquery.validate.js"
asp-fallback-test="window.jQuery && window.jQuery.validator"></script>
<script src="https://cdn.bootcss.com/jquery-validation-unobtrusive/3.2.11/jquery.validate.unobtrusive.js"
asp-fallback-src="~/node_modules/jquery-validation-unobtrusive/dist/jquery.validate.unobtrusive.js"
asp-fallback-test="window.jQuery && window.jQuery.validator && window.jQuery.validator.unobtrusive"></script>
</environment>
可以使用相似的方法配置 css 回落:
<environment include="Development">
<link href="~/node_modules/bootstrap/dist/css/bootstrap.css" rel="stylesheet" />
</environment>
<environment exclude="Development">
<link href="https://cdn.bootcss.com/twitter-bootstrap/4.3.1/css/bootstrap.css"
asp-fallback-href="~/node_modules/bootstrap/dist/css/bootstrap.css"
asp-fallback-test-class="sr-only"
asp-fallback-test-property="position"
asp-fallback-test-value="absolute"
rel="stylesheet">
</environment>
Gulp
官方推荐使用 Gulp 伺服前端库。
看了一下官方教程,还是 NPM + bundle + minify 好上手
