Go - how to organize code for dynamic packages


Go - how to organize code for dynamic packages

like below fixes the issue There are several ways to achieve your goal. Since Go does not support dynamically loaded libraries at the moment, you need to probably recompile your application whenever you add/remove any components. The simplest way therefore would be a yourapp/core package with the following:
an Application type with an ServeHTTP method that acts as your main application a Component interface that all your components have to implement. Your might want include a BaseUrl() string and a ServeHTTP method there. a Register method to your Application type, that can be used to add new components to your app.

it fixes the issue Well, $_POST is used exactly like $_GET, just need to change the input form to use post rather than get.
For the SQL, use JOINs to get to the data in the other tables, since that's essentially what you're doing anyway, you're just doing it manually, SELECT only what you need, and use LIMIT 1 where you expect a unique return.

Any of those help I'd say you should make a separate project for "X" if "X" can be used on its own or there are (or could be) at least 2 different projects that use "X". Otherwise, a package is fine.

I think the issue was by ths following , You won't be able to use the same struct for all union find implementations. For example weighted quick union requires array of tree sizes in addition to the elements.
What you are trying to achieve here is to have the same operations implemented differently. This is what interfaces are for in Go.
code :
package algorithms

type UnionFind interface {
    Union(a int, b int)
    Connected(a int, b int) bool
}

func QuickFind(n int) UnionFind {
    return &quickFind{......}
}

func QuickUnion(n int) UnionFind {
    return &quickUnion{......}
}

type quickUnion struct {
    ....
}

func (qu *quickUnion) Union(a int, b int) {
    ...
}

func (qu *quickUnion) Connected(a int, b int) bool {
    ...
}

type quickFind struct {
    ....
}

func (qf *quickFind) Union(a int, b int) {
    ...
}

func (qf *quickFind) Connected(a int, b int) bool {
    ...
}

this one helps. From https://herbertograca.com/2017/07/28/architectural-styles-vs-architectural-patterns-vs-design-patterns/
Architectural Style:
code :
Component-based
Monolithic application
Layered
Pipes and filters
Event-driven
Publish-subscribe
Plug-ins
Client-server
Service-oriented
Three-tier
Microkernel
Model-View-Controller
Model-View-ViewModel

Hope this helps First you have to choose a name for your project and write it to go.mod file. This name belongs to root directory of the project. Each new package you create must be located inside it's own subdirectory and its name should match directory name.
go.mod:
code :
module myprojectname
module github.com/myname/myproject
import myprojectname/stuff
import github.com/myname/myproject/stuff
import myprojectname/pkg/stuff
