webrpc-gen Golang templates

This repo contains the templates used by the webrpc-gen cli to code-generate webrpc Go server and client code.

Usage

webrpc-gen -schema=example.ridl -target=golang -out=./example.gen.go -pkg=main -server -client

# or 
webrpc-gen -schema=example.ridl -target=github.com/webrpc/gen-golang@v0.6.0 -out=./example.gen.go -pkg=main -server -client

# or
webrpc-gen -schema=example.ridl -target=./local-go-templates-on-disk -out=./example.gen.go -pkg=main -server -client

As you can see, the -target supports default golang, any git URI, or a local folder :)

Set custom template variables

Change any of the following values by passing -option="Value" CLI flag to webrpc-gen.

webrpc-gen -option	Default	Description	Added in
`-pkg=<name>`	`"proto"`	package name	v0.5.0
`-client`	`false`	generate client code	v0.5.0
`-server`	`false`	generate server code	v0.5.0
`-types=false`	`true`	don't generate types	v0.13.0
`-json=jsoniter`	`"stdlib"`	use alternative json encoding package	v0.12.0
`-fixEmptyArrays`	`false`	force empty array `[]` instead of `null` in JSON (see Go #27589)	v0.13.0
`-errorStackTrace`	`false`	enables error stack traces	v0.14.0
`-webrpcHeader`	`true`	enable client send webrpc version in http headers	v0.16.0

Example:

webrpc-gen -schema=./proto.json -target=golang -out server.gen.go -pkg=main -server

Set custom Go field meta tags in your RIDL file

CLI option flag	Description
`+ go.field.name = ID`	Set custom field name
`+ go.field.type = uuid.UUID`	Set custom field type (must be able to JSON unmarshal the value)
`+ go.type.import = github.com/google/uuid`	Set custom field type's import path
`+ go.tag.json = id`	Set `json:"id"` struct tag
`+ go.tag.db = id`	Set `db:"id"` struct tag

Example:

struct User
  - ID: int64
    + go.tag.db = id
    + go.tag.json = id
  - UUID: string
    + go.field.type = uuid.UUID
    + go.type.import = github.com/google/uuid
    + go.tag.json = uuid
    + go.tag.db = uuid
  - Age: int
    + go.tag.db: age
  - Name: string
    + go.tag.db = name
  - PasswordHash: string
    + go.tag.db = passwd_hash

will result in

import "github.com/google/uuid"

type User struct {
	ID           int64     `json:"id" db:"id"`
	UUID         uuid.UUID `json:"uuid" db:"uuid"`
	Name         string    `db:"name"`
	Age          int       `db:"age"`
	PasswordHash string    `json:"-" db:"passwd_hash"`
}
