How to launch an Angular project? Let's talk about the online process with nginx!

AngularHow to launch the project? The following article will talk about the launch process of Angular project in combination with nginx. I hope it will be helpful to everyone!

After we complete the angular project, how should you go online? [Related tutorial recommendations: "angular tutorial"]

Maybe you will answer:

It is not my bussiness. Right?

Indeed, as a pure front-end developer, after completing the development of the project, you do not need to touch the next online content.

However, as a developer, it is very important for us to understand the process of the project from development to launch.

Let’s explain it in combination with nginx.

Same for react and vue

Packaging project

What is used here is angular-cli generated project. After developing the project, you only need to run npm run build. builder will output according to the packaging content you preset in angular.json.

• outputPath: The packaged storage folder path
• index: Mount the template file
• main: The project's After the main entry file
• ...

is completed, you can view the packaged file through outputPath.

Install Nginx

We install it on the machine where we want to deploy the code, that is, the serverNginx. The operation is based on the yum source operation of centos.

# 安装nginx
yum -y install nginx

# 查看版本
nginx -v

# 启动nginx
systemctl start nginx.service

# 访问 默认是80端口
your_ip:80

Configure Nginx

View the configuration file nginx.conf of Nginx.

Use whereis nginx to find nginx The installation location

is in /etc/nginx/conf. Add a new configuration file to the d folder, such as demo.conf, and configure the server's interface address and front-end entry file path:

upstream api {
  server 127.0.0.1:8888; // 服务端
  keepalive 2000;
}

server {
  listen       [::]:80 default_server;
  server_name  _;
  root         /usr/share/nginx/demo-frontend/dist/demo-web; // 前端资源位置
  location / {
    add_header Access-Control-Allow-Origin *;
  }

  location /api { // api 处理
    proxy_pass http://api;
  }

}


# Settings for a TLS enabled server.

#     server {

#         listen       443 ssl http2 default_server;
#         listen       [::]:443 ssl http2 default_server;
#         server_name  _;
#         root         /usr/share/nginx/frontend/demo.com/dist;


#         ssl_certificate "/root/ssh/nginx/1_demo.com_bundle.crt";
#         ssl_certificate_key "/root/ssh/nginx/2_demo.com.key";
#         ssl_session_cache shared:SSL:1m;
#         ssl_session_timeout  10m;
#         ssl_ciphers HIGH:!aNULL:!MD5;
#         ssl_prefer_server_ciphers on;

#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        location / {
#.         add_header Access-Control-Allow-Origin *;
#        }


# to api restful service
#       location /api {
#         proxy_pass http://api;
#       }

#        error_page 404 /404.html;
#        location = /404.html {
#        }


#        error_page 500 502 503 504 /50x.html;
#        location = /50x.html {
#        }
#     }

Code comments Part of TLS is the transport encryption protocol https, and the corresponding certificate needs to be added.

In the above code, we store the front-end static resources under /usr/share/nginx/frontend/demo.com/dist/, then we will package Just upload the content under dist/** to this directory file.

/usr/share/nginx/frontend/demo.com/dist/ actually points to the index.html entry file.

A relatively simple upload solution is to execute it directly on the user's local machine: rsync -avzh server username@62.**1.**.**:/usr/share /nginx/frontend/demo.com/dist/ index.html and its similar contents under the /dist project. Synchronize the packaged content to the corresponding location of the remote server. Then restart nginx, that is, nginx -s reload and you’re done.

Summary

Let’s summarize the whole process:

• angular project packaging

• Server installation nginx

• nginx processing for back-end services

• nginx handles front-end content

• Upload the angular packaging file to the specified location on the server

Of course, you must apply for relevant information in advance The domain name, registration, related certificates, etc.

The idea is that simple. Of course, professional work should be left to operation and maintenance colleagues, don’t be too busy~
