Functions

func ExecuteProgram

func ExecuteProgram(p *goja.Program, args *ExecuteArgs, opts *ExecuteOptions) (result goja.Value, err error)

ExecuteProgram executes a compiled program with the default options. it deligates if a particular program should run in a pooled or non-pooled runtime

func Init

func Init(opts *types.Options) error

Init initializes the javascript protocol

func InternalGetGeneratorRuntime

func InternalGetGeneratorRuntime() *goja.Runtime

Internal purposes i.e generating bindings

func WrapScriptNCompile

func WrapScriptNCompile(script string, strict bool) (*goja.Program, error)

Wraps a script in a function and compiles it.

Types

type Compiler

type Compiler struct{}

Compiler provides a runtime to execute goja runtime based javascript scripts efficiently while also providing them access to custom modules defined in libs/.

func New

func New() *Compiler

New creates a new compiler for the goja runtime.

func (*Compiler) Execute

func (c *Compiler) Execute(code string, args *ExecuteArgs) (ExecuteResult, error)

Execute executes a script with the default options.

func (*Compiler) ExecuteWithOptions

func (c *Compiler) ExecuteWithOptions(program *goja.Program, args *ExecuteArgs, opts *ExecuteOptions) (ExecuteResult, error)

ExecuteWithOptions executes a script with the provided options.

type ExecuteArgs

type ExecuteArgs struct {
	Args        map[string]interface{} //these are protocol variables
	TemplateCtx map[string]interface{} // templateCtx contains template scoped variables
}

ExecuteArgs is the arguments to pass to the script.

func NewExecuteArgs

func NewExecuteArgs() *ExecuteArgs

NewExecuteArgs returns a new execute arguments.

type ExecuteOptions

type ExecuteOptions struct {
	// Callback can be used to register new runtime helper functions
	// ex: export etc
	Callback func(runtime *goja.Runtime) error

	// Cleanup is extra cleanup function to be called after execution
	Cleanup func(runtime *goja.Runtime)

	/// Timeout for this script execution
	Timeout int
	// Source is original source of the script
	Source *string

	Context context.Context
	// contains filtered or unexported fields
}

ExecuteOptions provides options for executing a script.

type ExecuteResult

type ExecuteResult map[string]interface{}

ExecuteResult is the result of executing a script.

func NewExecuteResult

func NewExecuteResult() ExecuteResult

func (ExecuteResult) GetSuccess

func (e ExecuteResult) GetSuccess() bool

GetSuccess returns whether the script was successful or not.
