A simple asserting library in Go inspired from ThePrimeagen to help checking values in before using them to check if the logic is correct.
It can also simplify error handling.
package main
import (
"log/slog"
"os"
"github.com/Jamlie/assert"
)
func main() {
val := 4
logsFile, err := os.OpenFile("logger.log", os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0644)
assert.NoError(err, "Cannot open file")
defer logsFile.Close()
jsonHandler := slog.NewJSONHandler(logsFile, nil)
logger := slog.New(jsonHandler)
logger.Info("Some message",
"user_id", val,
)

| NoError | Checks if the given error is nil, if not, logs out the error and panics with a specified message |
| Equals | Checks if two valeus are equal, if not, panics with a specified message |
| NotEquals | Checks if two valeus are not equal, if not, panics with a specified message |
| GreaterThan | Checks if the first value is greater than the second one, if not, panics with a specified message |
| LessThan | Checks if the first value is less than the second one, if not, panics with a specified message |
| GreaterThanEquals | Checks if the first value is greater than or equals the second one, if not, panics with a specified message |
| LessThanEquals | Checks if the first value is less than or equals the second one, if not, panics with a specified message |
| NotEmptySlice | Checks if a slice is not empty, if not, panics with a specified message |
