TinyTime
A minimal, portable time utility for Go and TinyGo with WebAssembly support. Automatically uses JavaScript Date APIs in WASM environments to keep binaries small.
Quick Start
import "github.com/cdvelop/tinytime"
func main() {
tp := tinytime.NewTimeProvider()
// Get current Unix timestamp in nanoseconds
nano := tp.UnixNano()
println("Current time:", nano)
// Convert Unix seconds to formatted date
date := tp.UnixSecondsToDate(1624397134)
println("Date:", date) // "2021-06-22 21:25"
// Convert Unix nanoseconds to time
time := tp.UnixNanoToTime(nano)
println("Time:", time) // "15:32:14"
}
API Reference
NewTimeProvider() TimeProvider
Creates a time provider instance. Automatically selects the appropriate implementation:
- WASM: Uses JavaScript Date APIs (smaller binaries)
- Standard Go: Uses
timepackage
UnixNano() int64
Returns current Unix timestamp in nanoseconds.
nano := tp.UnixNano()
// Example: 1624397134562544800
UnixSecondsToDate(seconds int64) string
Converts Unix timestamp (seconds) to formatted date string.
date := tp.UnixSecondsToDate(1624397134)
// Returns: "2021-06-22 21:25"
UnixNanoToTime(input any) string
Converts Unix timestamp (nanoseconds) to time string. Accepts multiple input types.
// All of these work:
time1 := tp.UnixNanoToTime(int64(1624397134000000000))
time2 := tp.UnixNanoToTime(1624397134000000000) // int
time3 := tp.UnixNanoToTime("1624397134000000000") // string
// Returns: "17:25:34"
Supported input types: int64, int, float64, string
WebAssembly Usage
When compiled for WebAssembly (GOOS=js GOARCH=wasm), tinytime automatically uses JavaScript's native Date APIs instead of bundling Go's time package. This results in significantly smaller binary sizes.
# Build for WebAssembly
GOOS=js GOARCH=wasm go build -o app.wasm .
# Run tests in browser
go install github.com/cdvelop/wasmtest@latest
wasmtest.RunTests("./tests", nil, 5*time.Minute)
Testing
Run standard tests:
go test
Run WebAssembly tests in browser:
go test -tags=wasm
Use Cases
- Frontend applications where binary size matters
- TinyGo projects requiring time utilities
- WebAssembly modules needing timestamp functionality
- Cross-platform libraries that work in both Go and browser environments
Dependencies

Types ¶
type TimeProvider ¶
type TimeProvider interface {
// UnixNano retrieves the current Unix timestamp in nanoseconds.
// It creates a new JavaScript Date object, gets the timestamp in milliseconds,
// converts it to nanoseconds, and returns the result as an int64.
// eg: 1624397134562544800
UnixNano() int64
// ts := int64(1609459200) // January 1, 2021 00:00:00 UTC
// formattedDate := UnixSecondsToDate(ts)
// println(formattedDate) // Output: "2021-01-01 00:00:00"
UnixSecondsToDate(int64) string
// UnixNanoToTime converts a Unix timestamp in nanoseconds to a formatted time string.
// Format: "15:04:05" (hour:minute:second)
// It accepts a parameter of type any and attempts to convert it to an int64 Unix timestamp in nanoseconds.
// eg: 1624397134562544800 -> "15:32:14"
// supported types: int64, int, float64, string
UnixNanoToTime(any) string
}
TimeProvider define la interfaz para utilidades de tiempo implementada tanto para Go estándar como para WASM/JS.
func NewTimeProvider ¶
func NewTimeProvider() TimeProvider
NewTimeProvider retorna la implementación correcta según el entorno de compilación.
