Midway Static File Component

Static server plugin for egg, base on koa-static-cache.

Install

$ npm i @midwayjs/static-file --save

available in koa/egg/faas.

Usage

import info component in configuration.ts file

import * as koa from '@midwayjs/koa';
import * as staticFile from '@midwayjs/static-file';
import { join } from 'path';

@Configuration({
  imports: [
    koa,
    staticFile,
  ],
  importConfigs: [
    join(__dirname, './config')
  ]
})
export class ContainerConfiguration {
}

support all configurations in koa-static-cache. and with default configurations below:

• dynamic: true
• preload: false
• maxAge: 31536000 in prod env, 0 in other envs
• buffer: true in prod env, false in other envs

provides one more option:

• maxFiles: the maximum value of cache items, only effective when dynamic is true, default is 1000.

All static files in $appDir/public can be visited with prefix /public, and all the files are lazy loaded.

• In non-production environment, assets won't be cached, your modification can take effect immediately.
• In production environment, @midwayjs/static-file will cache the assets after visited, you need to restart the process to update the assets.
• Dir default is $appDir/public but you can also define multiple directory by default, static server will use all these directories.

// {app_root}/src/config/config.default.ts
export const staticFile = {
  dirs: {
    default: {
      prefix: '/public',
      dir: 'xxx'
    },
    antoherDir: {
      prefix: '/',
      dir: 'xxx'
    }
  }
};

if you want to override default prefix, just set dirs.default.

// {app_root}/src/config/config.default.ts
export const staticFile = {
  dirs: {
    default: {
      prefix: '/',
    },
  }
};
