dot

Component development specification, including component definition, component dependencies, component life cycle, dependency injection, and common basic components

• Dot: A component which has no type or interface requirements, anything can be a component
• Line: A container that holds components, adds, deletes, modifies, and injects dependencies into components
• Newer: Construct component, the Newer is used to construct the component, and if it is not specified, then construct it by default "refect.New"
• Lifer: Is the component life cycle management interface, the implementation of the interface and the method will be automatically run by Line, the following are the four interfaces

Creator
Starter
Stopper
Destroyer

• Injecter ：It is component dependency injection, adding, deleting and checking components. The creation process of components added through this interface is completed by ourselves, which is part of Line

The process that component runs as follows：

---

Create Config and Log

1. Make Default Log
2. Make Config
3. Make Log of config

---

Create

1. Builder.BeforeCreate
2. dot.Newer
3. dot.SetterLine
4. dot.SetterTypeAndLiveId
5. Events.BeforeCreate //for type id
6. Events.BeforeCreate //for live id
7. dot.Creator
8. Events.AfterCreate //for live id
9. Events.AfterCreate //for type id, go to "2. Newer", untill all done
10. Inject all dependentes of dots
11. AfterAllInjecter
12. Builder.AfterCreate

---

Start

1. Builder.BeforeStart
2. Events.BeforeStart
3. Events.BeforeStart //for live id
4. dot.Starter
5. Events.AfterStart //for live id
6. Events.AfterStart //go to "2. Events.BeforeStart", untill all done
7. dot.AfterAllStart
8. Builder.AfterStart

---

Stop

1. Builder.BeforeStop
2. dot.BeforeAllStopper
3. Events.BeforeStop //for type id
4. Events.BeforeStop //for live id
5. dot.Stopper
6. Events.AfterStop //for live id
7. Events.AfterStop //for type id go to "2. Events.BeforeStop", until all done
8. Builder.AfterStop

---

Destroy

1. Builder.BeforeDestroy
2. Events.BeforeDestroy //for type id
3. Events.BeforeDestroy //for live id
4. dot.Destroyer
5. Events.AfterStop //for live id
6. Events.AfterStop //for type id go to "2. Events.BeforeDestroy", until all done
7. Builder.AfterDestroy

The relationships between components can be set by configuration files or code, Line computes the dependencies between components, regardless of the order in which they are created .

Default components

Config: dots/sconfig

Now use the json format, later will support toml, yaml, command line, and environment variables.

Log: dots/slog

High performance logs based on zap.

GRPC client balance: dots/grpc/conns

Client load balancing for GRPC. "sample /grpc_conns" is an example.

Certificate generated: dots/certificate

Generate root and sub certificates. "sample/certificate" is an example.

Code Style -- Go
