Customise ng serve to proxy calls to /api?

阅读更多关于 Customise ng serve to proxy calls to /api?

I created a new application with ng CLI, works like a charm: ng new babysteps cd babysteps ng serve ng serve uses webpack to assemble the app. To fully test it, I need to serve /api... from my API mock server (specifically the POST requests). How can I customise the web server used, to redirect that one URL pattern? The Webpack dev server has a proxy setting , but it seems (?) ng serve doesn't have a config file (or I didn't get). Do I need to create a webpack.config.js or create/edit some other file to proxy ? Fredrik Lundin You can indeed setup a proxy to backend with the angular cli, with

Change hard coded url constants for different environments via webpack

阅读更多关于 Change hard coded url constants for different environments via webpack

I have a ApiCaller.js module which generate calls to our api server to get data. It has const field API_URL which points to server url. This API_URL const changes for dev and prod environments. So when I need to deploy to dev environment I need to change that url ( API_URL ) manually to point to dev-api-server and vice-versa. I want these configuration parameters outside the code and during build process I want to change them dynamically so that I can build with different settings. I am using webpack to bundle my javascript, html, css files. You can store your API_URL in webpack config: //

webpack---less 热更新使用

阅读更多关于 webpack---less 热更新使用

　　最近尝试用less写界面,webpack进行打包，然后发现每次修改less时都需要重新执行webpack打包一下，于是就想到了webpack热更新这个功能。一、使用less 　　less是一门css预处理语言，它是拓展了css，增加了变量，Mixin等等。使用less需要安装less服务，less-loader用来打包时用，想要将less正确解析成css当然还需要style-loader和css-loader。loader是webpack重要的功能之一，通过使用不同的loader，webpack可以使用外部脚本或工具处理不同格式类型的文件，如通过less-loader处".less"文件。首先安装： npm install less --save-dev npm install style-loader css-loader less-loader --save-dev webpack.config.js配置： module: { rules: [{ test: /\.less$/ , use: [ 'style-loader', 'css-loader', 'less-loader' ] }] } 然后将.less文件加载到入口文件里，如在入口文件里import '../less/topHead.less';这样就可以执行webpack把.less文件进行打包了。二

Webpack watch not working on Webstorm on Windows?

阅读更多关于 Webpack watch not working on Webstorm on Windows?

So basically I have a project using Webpack, if I build using Webpack -w , editing the file with another editor will trigger the watch; however if I edit the file using Webstorm, nothing will happen. I have came across this post , which seems I'm not the only one, however that solution is for Ubuntu, so I was wondering if there is anything similar for Windows? Thanks seems Webpack watch doesn't work if the file is not saved directly. Please try turning ' Safe write ' option ( Settings | Appearance & Behavior | System Settings | Use "safe write" (save changes to temporary file first) ) off Also

Webpack 4.X 从入门到精通 - devServer与mode（三）

阅读更多关于 Webpack 4.X 从入门到精通 - devServer与mode（三）

上一篇文章里详细介绍了一下插件的用法，这一篇文章接着丰富 module.exports 里的属性。如今的前端发展已经非常迅速了，伴随而来的是开发模式的转变。现在已经不再是写个静态页面并放在浏览器里打开预览一下了。在实际的开发中会经常需要使用 http 服务器，比如之前的 ajax ，想要看到效果就必需搭建一个服务器。搭建服务器的方式有非常的多，而 webpack 则原生的提供服务器的支持，大家无需再去下载软件。同时它还提供了自动刷新、热更新等功能，使开发变得非常方便。 devServer 安装使用 npm i webpack-dev-server -D 打开终端，并进入到对应的项目里（我的为 webpack-demo ），执行命令 webpack-dev-server ，如果终端里显示如下则表示已经成功开启服务器注意： 1、此时可能会提示 webpack-dev-server 不是内部命令，解决办法为在全局再次安装一下 webpack-dev-server 模块，或者在 package.json 里的 scripts 里加上 "dev": "webpack-dev-server" ，然后执行命令 npm run dev 2、此时我并没有通过 webpack 命令生成一个 dist 目录（目录结构如下图），然后在浏览器里输入地址 http://localhost:8080/ 后

Im trying to organize a webpack 2 template for my personal projects with webpack-dev-server and run it with the npm commands, but i'm getting this error: Configuration file found but no entry configured. It's weird because the entry is defined and i tested the resolved route, it's fine, so here is my webpack config, the command to run it and the file to configure the loaders: webpack.config.dev.js const path = require('path'); const fs = require('fs'); const configs = require('./dev-wpk-conf'); const HtmlPlugin = require('html-webpack-plugin'); const Dotenv = require('dotenv-webpack'); const
