Angular 打包 js文件 过大

1、加了--prod参数后，angular-cli会把用不到的包都删掉

//package.json 中
"scripts": {
...
"build": "ng build --prod"
...
}

2、nginx开启gzip优化、在nginx中server或http内上，添加这段代码

gzip  on;
gzip_static on;
gzip_comp_level 2;
gzip_http_version 1.0;
gzip_proxied any;
gzip_min_length 1100;
gzip_buffers 16 8k;
gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
# Disable for IE < 6 because there are some known problems
gzip_disable "MSIE [1-6].(?!.*SV1)";
# Add a vary header for downstream proxies to avoid sending cached gzipped files to IE6
gzip_vary on;

 

nginx 报错：

C:\WebData\nginx-1.18.0>nginx.exe -t
nginx: [warn] the "ssl" directive is deprecated, use the "listen ... ssl" directive instead in C:\WebData\nginx-1.18.0/conf/nginx.conf:138
nginx: [emerg] unknown directive "锘縮erver" in C:/WebData/nginx-1.18.0/conf/conf.d/familyxiaomobile.conf:1
nginx: configuration file C:\WebData\nginx-1.18.0/conf/nginx.conf test failed

原因是其中一个文件格式为utf-8 +BOM 的格式，另存为 utf-8 就对了
