An extremely simple and powerful Go struct to Typescript Class generator.
Inspired by tkrajina/typescriptify-golang-structs.
go get -u -v github.com/OneOfOne/struct2ts/...
- Fairly decent command line interface if you don't wanna write a generator yourself.
- Automatically handles Go
int64timestamps<->JavascriptDate. - Automatically handles json tags.
-omit this field.datehandle convertingtime.Time{}.Unix() <-> javascript Date.,no-nullonly valid for struct fields, forces creating a new class rather than usingnullin TS.,nullallows any field type to benull.
- Input:
type OtherStruct struct {
T time.Time `json:"t,omitempty"`
}
type ComplexStruct struct {
S string `json:"s,omitempty"`
I int `json:"i,omitempty"`
F float64 `json:"f,omitempty"`
TS *int64 `json:"ts,omitempty" ts:"date,null"`
T time.Time `json:"t,omitempty"` // automatically handled
NullOther *OtherStruct `json:"o,omitempty"`
NoNullOther *OtherStruct `json:"nno,omitempty" ts:",no-null"`
}- Output:

// ...exports...➤ struct2ts -h
usage: struct2ts [<flags>] [<pkg.struct>...]
Flags:
-h, --help Show context-sensitive help (also try --help-long
and --help-man).
--indent="\t" Output indentation.
-m, --mark-optional-fields Add `?` to fields with omitempty.
-6, --es6 generate es6 code
-C, --no-ctor Don't generate a ctor.
-T, --no-toObject Don't generate a Class.toObject() method.
-E, --no-exports Don't automatically export the generated types.
-D, --no-date Don't automatically handle time.Unix () <-> JS
Date().
-H, --no-helpers Don't output the helpers.
-N, --no-default-values Don't assign default/zero values in the ctor.
-i, --interface Only generate an interface (disables all the other
options).
-s, --src-only Only output the Go code (helpful if you want to
edit it yourself).
-p, --package-name="main" the package name to use if --src-only is set.
-k, --keep-temp Keep the generated Go file, ignored if --src-only
is set.
-o, --out="-" Write the output to a file instead of stdout.
-V, --version Show application version.
Args:
[<pkg.struct>] List of structs to convert (github.com/you/auth/users.User,
users.User or users.User:AliasUser).
type CustomTypescript interface {
RenderCustomTypescript(w io.Writer) (err error)
}If your model implements a RenderCustomTypescript(w io.Writer) (err error) function it will inject what ever you
write to the writer at the end of the model. struct2ts will handle the first level of indenting for you.
- Use xast to skip reflection.
- Support annoymous structs.
Support ES6.
