♻️API vs SDK: Key Differences

APIs (Application Programming Interfaces) and SDKs (Software Development Kits) are essential tools for software development, but they serve different purposes:

API:
An API is a set of rules and protocols that allows different software applications and services to communicate and share data.

1. Defines a standard interface for components to interact.

2. Allows integration between software written in different languages and frameworks.

3. Typically provides endpoints for requesting and serving data..

SDK:
An SDK is a comprehensive package of tools, libraries, sample code, and documentation to simplify building apps on a specific platform, framework, or hardware.

1. Provides higher-level abstractions to ease development for a target platform.

2. Designed to integrate seamlessly with the underlying platform, ensuring compatibility and optimal performance.

3. Grants access to platform-specific capabilities and features that may be complex to implement from scratch.

The choice between APIs and SDKs depends on the project's goals and technical needs. APIs offer platform-agnostic interoperability, while SDKs provide convenient access to proprietary platform functionality.

✅ Pitfalls: avoid unintentional recursion or other issues that could lead to stack overflow json marshal or unmarshal

code:

package main

import (
  "encoding/json"
  "fmt"
  "log"
)

type Person struct {
  Name string `json:"name"`
  Age int `json:"age"`
}

type Person2 struct {
  Name string `json:"name"`
  Age int `json:"age"`
}

func (p *Person) MarshalJSON() ([]byte, error) {
  var person Person
  person = *p
  return json.Marshal(person)
}

func (p *Person2) MarshalJSON() ([]byte, error) {
  return json.Marshal(p)
}

func main() {
  person := new(Person)
  person.Name = "Javad"
  person.Age = 29

  b, err := person.MarshalJSON()
  if err != nil {
    log.Fatal(err)
  }

  fmt.Println(string(b))

  person2 := new(Person2)
  person2.Name = "Javad"
  person2.Age = 29

  b, err = person2.MarshalJSON()
  if err != nil {
    log.Fatal(err)
  }

  fmt.Println(string(b))
}

output:

{"name":"Javad","age":29}

runtime: goroutine stack exceeds 1000000000-byte limit
runtime: sp=0xc020160390 stack=[0xc020160000, 0xc040160000]
fatal error: stack overflow

MarshalJSON person 2 this creates a recursive loop, causing the stack to grow until it exceeds the limit, resulting in a stack overflow error.

What is the maximum stack size for Goroutine?

While the minimum stack size is defined as 2048 bytes, the Go runtime does also not allow goroutines to exceed a maximum stack size; this maximum depends on the architecture and is 1 GB for 64-bit and 250MB for 32-bit systems.

✅ مشارکت و انجام issue به همراه bounty

در زیر تسکی داریم خیلی مهم هستش و همچنین برای شروع مشارکت در پروژه آزاد مناسب می باشد.

https://github.com/pactus-project/pactus/issues/805

توضیحات درخصوص تسک:

ما از کاربران گزارش‌های زیادی دریافت کرده‌ایم که نمی‌توانند نود خود را اجرا کنند به دلیل خطای 'منبع به طور موقت در دسترس نیست'. این مشکل زمانی پیش می‌آید که در حال حاضر یک نود در پس‌زمینه در حال اجرا است و کاربران تلاش می‌کنند تا یک نود جدید را شروع کنند. ما باید یک راه برای شناسایی اینکه یک نمونه از Pactus در حال اجرا است را پیدا کنیم. اگر چنین است، باید کاربر را قبل از تلاش برای شروع یک نود جدید مطلع کنیم تا از این خطا جلوگیری شود.
