This is a library to load NodeJS script in runtime, either in a file or in plain text.

enableLastModifiedCheck(value: boolean)

Whether to enable last modified check on module cache. Enabled by default. If disabled, will always return cached module.

requireSync(filepath: string, context: any = {})
requireAsync(filepath: string, context: any = {})

Load modules from file.
In case you are using requireAsync, there will be a requireAsync function in global context of the processed file.
Note that using await without async will result to syntax error.
Please check the example.

runSync(code: string, filepath: string, context: any = {})
runAsync(code: string, filepath: string, context: any = {})

Load modules from plain text. A actual/virtual file path should be provided.
In case this is a virtual file path, by default the cache will be expired after 30 mins if a positive maxAge is not provided

registerTranspiler(transpiler: Transpiler)

Register a transpier to transpile and run script.
By default JsTranspiler and JsonTranspiler are registered.

Transpiler

interface Transpiler {
  // check from the file path if the file is valid for this transpiler
  check(path: string): boolean

  // transpile the code to, possibly, JavaScript
  transpile(path: string, code: string): string

  // run the transpiled code
  // you should use the one declared in JsTranspiler
  run<T>(path: string, code: string, require: NodeRequire, baseContext: any): T | undefined

  // run the transpiled code in async context
  // you should use the one declared in JsTranspiler
  runAsync<T>(path: string, code: string, require: NodeRequire, baseContext: any): Promise<T | undefined>
}
