How to set up a development environment for angularjs? Analysis of the process of building a development environment with angularjs

This article mainly introduces about building the development environment for angularjs. Here is the process of building the angularjs development environment. If you haven’t read what you want to see, let’s start reading this article together

1. First, let’s briefly introduce the features of Angular-cli:

Angular-cli can quickly build a framework and create modules, services, classes, directives, etc.;

It has the function of webpack, which can realize code separation, on-demand loading, etc.;

Automatically configure the development environment, Test environment and production environment can realize code packaging, compression and hot deployment, as well as module testing and end-to-end testing.

Angular-cli can automatically identify the pre-compilation of sass and less through the suffix;

Angular-cli can configure TypeScript when creating, and can also make some personalized configurations;

The project structure created through Angular-cli is a best practice and can be used in production environments;

2. Now start installing nodejs:

AngularJS needs to use Nodejs, so we need to install nodejs first and need to use nodejs. The download address of nodejs is: https: //nodejs.org/en/download/ (If you want to see more, go to the PHP Chinese websiteAngularJS Reference Manual column)

3. You need to install npm and cnpm## here

#The next step is to install npm.

NPM is a package management tool installed along with NodeJS. It can solve many problems in NodeJS code deployment. Common usage scenarios include the following:

Allow users to download third-party packages written by others from the NPM server for local use.

Allows users to download and install command line programs written by others from the NPM server for local use.

Allows users to upload packages or command line programs written by themselves to the NPM server for others to use.

The installation of nodejs and npm has been completed here, but there will be some problems if you use npm to install it in Datianchao, so we use cnpm to install it, which is also a package of npm.

Install cnpm, execute the command: npm i -g cnpm

After executing this command, wait for completion, then enter cnpm version to check whether the installation is completed. I have already installed it here, so you can go in .

After installing cnpm, we start to install Angular-cli.

Execute the command: cnpm i -g angular-cli

Then you can execute the ng version command to check whether the installation is complete and the version of angular-cli

After the installation is completed, we You can use the ng command to start creating the project.

4. Now you need to create the project:

After installing angular-cli, you can create the project directly. Execute the command: ng new JustForTest

Among them, JustForTest is the project name

Executing this command will create a lot of files, and you need to wait for a while. This step will take a long time, and you need to wait until the installation of nod_.modules is completed.

Use ng serve to start directly.

In this way, you can start the project directly. We enter in the browser: http://localhost:4200 and you can directly access:

5. The project is now being imported

If we are looking for a project from the Internet, how do we start it locally? Let’s do it in detail:

I recommend everyone to take a look at this tutorial by Teacher Da Mo: The Angular2.0 video tutorial is here

. For the demonstration here we also use a project of Teacher Da Mo: NiceFish , first we need to clone the project through git, which will not be demonstrated here. This is the project address of NiceFish: http://git.oschina.net/mumu-osc/NiceFish

After the project is cloned , the command line enters the directory where the project is located.

Execute command: cnpm i -g @angular/cli

Let me explain here, before we installed the global angular-cli.

Wait for the command execution to complete, then execute the command: cnpm install

Then execute the command: ng serve -prod -aot

Then wait for the compilation to complete.

After completion, we can enter in the browser:

http://localhost:4200 to access the project.

Then, there is no more. This article about the angularjs construction and development process ends here (if you want to see more angularjs related knowledge, go to the PHP Chinese website
