Re: [go-nuts] imported and not used "errors"
I find the Gin documentation (and the examples provided by the project) to
be, ahem, lacking in important details. As you can see from the source (
https://github.com/gin-gonic/gin/blob/78dad9d77d8c2d679dedea1fbef5fc8a54372efd/gin.go#L372)
the Run() function returns an error that will tell you binding to port 8080
failed.
While Gin may be a great project (I've never used it) you don't need a
framework like it for your simple example The standard net/http package
works just fine for simple use cases.

Re: [go-nuts] imported and not used "errors"
Something is already running on localhost port 8080. use a different port.

[go-nuts] imported and not used "errors"
I am following a tutorial to great an API in Go with a framework called Gin.
I have imported errors and created a function like so;
func createBook(c *gin.Context) {
var newBook book
if err := c.BindJSON(); err != nil {
return
}
books = append(books, newBook)
c.IndentedJSON(http.StatusCreated, newBook)
}
func main is as follows;
func main() {
//1.router responsible for handling different routes and diff endpoints
of API
router := gin.Default()
//2.the route we are handling is /books, ie when u go to
localhost:8080/books it will call getBooks()function
router.GET("/books", getBooks)
router.POST("/books", createBook)
router.Run("localhost:8080")
}
If i simply ignore the import error I get this;
[GIN-debug] Listening and serving HTTP on localhost:8080
[GIN-debug] [ERROR] listen tcp 127.0.0.1:8080: bind: address already in use
I've gone over the tutorial several times and I'm not sure how he isn't
getting the erros.
On another note are there any good recommendations for documentation to
create an API without a framework?
