 1 | # React + TypeScript + Vite
 2 | 
 3 | This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
 4 | 
 5 | Currently, two official plugins are available:
 6 | 
 7 | - [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh
 8 | - [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
 9 | 
10 | ## Expanding the ESLint configuration
11 | 
12 | If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:
13 | 
14 | - Configure the top-level `parserOptions` property like this:
15 | 
16 | ```js
17 | export default {
18 |   // other rules...
19 |   parserOptions: {
20 |     ecmaVersion: 'latest',
21 |     sourceType: 'module',
22 |     project: ['./tsconfig.json', './tsconfig.node.json'],
23 |     tsconfigRootDir: __dirname,
24 |   },
25 | }
26 | ```
27 | 
28 | - Replace `plugin:@typescript-eslint/recommended` to `plugin:@typescript-eslint/recommended-type-checked` or `plugin:@typescript-eslint/strict-type-checked`
29 | - Optionally add `plugin:@typescript-eslint/stylistic-type-checked`
30 | - Install [eslint-plugin-react](https://github.com/jsx-eslint/eslint-plugin-react) and add `plugin:react/recommended` & `plugin:react/jsx-runtime` to the `extends` list
31 |

  1 | # Equivalent of `npm init` in Go
  2 | 
  3 | ```bash
  4 | go mod init <module_name>
  5 | ```
  6 | 
  7 | -   `go mod init` is used to initialize a new module.
  8 | -   It creates a new `go.mod` file in the current directory.
  9 | -   The `go.mod` file contains information about the module, its dependencies, and the Go version.
 10 | 
 11 | # Equivalent of `npm run start` in Go
 12 | 
 13 | ```bash
 14 | go run <main_file.go>
 15 | ```
 16 | 
 17 | -   `go run` is used to compile and run a Go program.

 19 | 
 20 | # Equivalent of `npm install <package_name>` in Go
 21 | 
 22 | ```bash
 23 | go get <package_name>
 24 | ```
 25 | 
 26 | -   `go get` is not a package manager.
 27 | -   `go get` is used to download and install packages from remote repositories.
 28 | -   It does not handle versioning.
 29 | -   This command fetches the package and its dependencies (if any)
 30 | 
 31 | # Equivalent of `package.json` in Go
 32 | 
 33 | ```bash
 34 | go.mod file
 35 | ```
 36 | 
 37 | -   It contains information about the module, its dependencies, and the Go version.
 38 | 
 39 | # Equivalent of `npm install` in Go
 40 | 
 41 | ```bash
 42 | go mod tidy
 43 | ```
 44 | 
 45 | -   `go mod tidy` is used to add missing and remove unused modules.
 46 | -   It updates the go.mod file to use the latest version of the dependencies.
 47 | 
 48 | # Equivalent of `JSON.stringify()` in Go
 49 | 
 50 | ```go
 51 | import "encoding/json"
 52 | 
 53 | func main() {
 54 |     data := map[string]interface{}{
 55 |         "name": "John Doe",
 56 |         "age": 30,
 57 |     }
 58 | 
 59 |     jsonString, err := json.Marshal(data)
 60 |     if err != nil {
 61 |         fmt.Println(err)
 62 |         return
 63 |     }
 64 | 
 65 |     fmt.Println(string(jsonString))
 66 | }
 67 | ```
 68 | 
 69 | -   `json.Marshal()` is used to convert a Go data structure to a JSON string.
 70 | 
 71 | # Equivalent of `JSON.parse()` in Go
 72 | 
 73 | ```go
 74 | import "encoding/json"
 75 | 
 76 | func main() {
 77 |     jsonString := `{"name":"John Doe","age":30}`
 78 | 
 79 |     var data map[string]interface{}
 80 |     err := json.Unmarshal([]byte(jsonString), &data)
 81 |     if err != nil {
 82 |         fmt.Println(err)
 83 |         return
 84 |     }
 85 | 
 86 |     fmt.Println(data)
 87 | }
 88 | ```
 89 | 
 90 | -   `json.Unmarshal()` is used to convert a JSON string to a Go data structure.
 91 | 
 92 | # Equivalent of `nodemon` in Go
 93 | 
 94 | ```bash
 95 | go install github.com/cosmtrek/air@latest
 96 | ```
 97 | 
 98 | -   `air` is a live reload tool for Go applications.
 99 | -   It watches for file changes and automatically rebuilds and restarts the application.
100 | -   It is similar to `nodemon` in the Node.js ecosystem.
101 | -   There are other tools like `fresh` which can also be used for live reloading in Go.
102 | 
103 | # Equivalent of `dotenv` in Go
104 | 
105 | ```bash
106 | go get github.com/joho/godotenv
107 | ```
108 | 
109 | -   `godotenv` is a Go package that loads environment variables from a `.env` file.
110 | -   It is similar to `dotenv` in the Node.js ecosystem.
111 | -   It allows developers to store sensitive information like API keys, database URIs, etc., in a `.env` file and load them into the application.
112 | 
113 | ## Code Example of Using `godotenv`
114 | 
115 | ```go
116 | package main
117 | 
118 | import (
119 |   "fmt"
120 |   "log"
121 |   "os"
122 | 
123 |   "github.com/joho/godotenv"
124 | )
125 | 
126 | func main() {
127 |   err := godotenv.Load(".env")
128 |   if err != nil {
129 |     log.Fatal("Error loading .env file")
130 |   }
131 | 
132 |   MONGODB_URI := os.Getenv("MONGODB_URI")
133 | }
134 | ```
135 | 
136 | -   In this example, we load environment variables from a `.env` file using `godotenv.Load(".env")`.
137 | -   We can then access the environment variables using `os.Getenv("MONGODB_URI")`.
138 | 
139 | # Equivalent of `Express.js` in Go
140 | 
141 | ```bash
142 | go get github.com/gofiber/fiber/v2
143 | ```
144 | 
145 | -   `Fiber` is a web framework for Go that is inspired by Express.js.
146 | -   It is fast, lightweight, and easy to use.
147 | -   It provides a similar API to Express.js, making it easy for developers familiar with Express.js to transition to Go.
148 | -   Other popular web frameworks in Go include `Gin` and `Echo`.
149 | 
150 | # Equivalent of `Express.js Middleware` in Go
151 | 
152 | ```go
153 | func main() {
154 |     app := fiber.New()
155 | 
156 |     app.Use(middleware)
157 | 
158 |     app.Get("/", func(c *fiber.Ctx) error {
159 |         return c.SendString("Hello, World!")
160 |     })
161 | 
162 |     app.Listen(":3000")
163 | }
164 | func middleware(next http.Handler) http.Handler {
165 |     return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
166 |         // Middleware logic
167 | 
168 |         // .
169 |         // .
170 |         // .
171 | 
172 |         next.ServeHTTP(w, r)
173 |     })
174 | }
175 | ```
176 | 
177 | -   In this example, we define a middleware function that takes the `next` handler as an argument.
178 | -   The middleware function wraps the `next` handler and executes some logic before calling the `next` handler.
179 | 
180 | # Equivalent of `Express.js Route Handling` in Go
181 | 
182 | ```go
183 | func main() {
184 |     app := fiber.New()
185 | 
186 |     app.Get("/", helloHandler)
187 | 
188 |     app.Listen(":3000")
189 | }
190 | 
191 | func helloHandler(c *fiber.Ctx) error {
192 |     return c.SendString("Hello, World!")
193 | }
194 | ```
195 | 
196 | -   In this example, we define a route handler function `helloHandler` that sends a response back to the client.
197 | -   We then register the route handler with the `app.Get()` method, specifying the route path and the handler function.
198 |
