Then you can start with code below
const Application = require('egg-core').EggCore;
const app = new Application({
baseDir: '/path/to/app'
});
app.ready(() => app.listen(3000));
EggLoader can easily load files or directories in your egg project. In addition, you can customize the loader with low level APIs.
Load config/plugin.js
Load config/config.js and config/{serverEnv}.js
If process.env.EGG_APP_CONFIG
is exists, then it will be parse and override config.
Load app/controller
Load app/middleware
Load app/extend/application.js
Load app/extend/context.js
Load app/extend/request.js
Load app/extend/response.js
Load app/extend/helper.js
Load app.js, if app.js export boot class, then trigger configDidLoad
Load agent.js, if agent.js export boot class, then trigger configDidLoad
Load app/service
Retrieve application environment variable values via serverEnv
. You can access directly by calling this.serverEnv
after instantiation.
serverEnv | description |
---|---|
default | default environment |
test | system integration testing environment |
prod | production environment |
local | local environment on your own computer |
unittest | unit test environment |
To get directories of the frameworks. A new framework is created by extending egg, then you can use this function to get all frameworks.
A loadUnit is a directory that can be loaded by EggLoader, cause it has the same structure.
This function will get add loadUnits follow the order:
loadUnit has a path and a type. Type must be one of those values: app, framework, plugin.
{
path: 'path/to/application',
type: 'app'
}
To get application name from package.json
Get the infomation of the application
package.json
package.json
To load a single file. Note: The file must export as a function.
To load files from directory in the application.
Invoke this.loadToApp('$baseDir/app/controller', 'controller')
, then you can use it by app.controller
.
To load files from directory, and it will be bound the context.
// define service in app/service/query.js
module.exports = class Query {
constructor(ctx) {
super(ctx);
// get the ctx
}
async get() {}
};
// use the service in app/controller/home.js
module.exports = async ctx => {
ctx.body = await ctx.service.query.get();
};
Loader app/extend/xx.js to target, For example,
this.loadExtend('application', app);
Param | Type | Description |
---|---|---|
directory | String/Array |
directories to be loaded |
target | Object |
attach the target object from loaded files |
match | String/Array |
match the files when load, default to **/*.js (if process.env.EGG_TYPESCRIPT was true, default to [ '**/*.(js|ts)', '!**/*.d.ts' ] ) |
ignore | String/Array |
ignore the files when load |
initializer | Function |
custom file exports, receive two parameters, first is the inject object(if not js file, will be content buffer), second is an options object that contain path |
caseStyle | String/Function |
set property's case when converting a filepath to property list. |
override | Boolean |
determine whether override the property when get the same name |
call | Boolean |
determine whether invoke when exports is function |
inject | Object |
an object that be the argument when invoke the function |
filter | Function |
a function that filter the exports which can be loaded |
EggCore record boot progress with Timing
, include:
process.uptime
to record the script start running time, framework can implement a prestart file used with node --require
options to set process.scriptTime
)require
durationStart record a item. If the item exits, end the old one and start a new one.
End a item.
Generate all record items to json
