Overview

Package compiler implements additional functionality for k6 to compile js code. more specifically transpiling through babel in case that is needed.

Types

type Compiler

type Compiler struct {
	Options Options
	// contains filtered or unexported fields
}

A Compiler compiles JavaScript source code (ES5.1 or ES6) into a goja.Program

func New

func New(logger logrus.FieldLogger) *Compiler

New returns a new Compiler

func (*Compiler) Compile

func (c *Compiler) Compile(src, filename string, isESM bool) (*goja.Program, string, error)

Compile the program in the given CompatibilityMode, wrapping it between pre and post code TODO isESM will be used once goja support ESM modules natively

func (*Compiler) Transform

func (c *Compiler) Transform(src, filename string, inputSrcMap []byte) (code string, srcMap []byte, err error)

Transform the given code into ES5

type Options

type Options struct {
	CompatibilityMode lib.CompatibilityMode
	SourceMapLoader   func(string) ([]byte, error)
	Strict            bool
}

Options are options to the compiler

type Pool

type Pool struct {
	// contains filtered or unexported fields
}

Pool is a pool of compilers so it can be used easier in parallel tests as they have their own babel.

func NewPool

func NewPool(logger logrus.FieldLogger, count int) *Pool

NewPool creates a Pool that will be using the provided logger and will preallocate (in parallel) the count of compilers each with their own babel.

func (*Pool) Get

func (c *Pool) Get() *Compiler

Get a compiler from the pool.

func (*Pool) Put

func (c *Pool) Put(co *Compiler)

Put a compiler back in the pool.
