gulp-mock-module

A module replacement plugin for gulp. It serves mock files by changing the require/import target from the target module onto the mock for that module.

Read me for gulp 3

Usage

First, install gulp-mock-module as a development dependency:

npm install --save-dev gulp-mock-module
# or
yarn add --dev gulp-mock-module

Then, add it to your gulpfile.js:

const mock = require("gulp-mock-module");
const path = require("path");
const { src, dest } = require("gulp");

function replaceTemplate() {
  return src(["file.js"])
    .pipe(
      mock(
        ["module1", "module2"],
        path.resolve(process.cwd(), "folder-that-contains-the-mocks")
      )
    )
    .pipe(dest("build/"));
}

exports.replaceTemplate = replaceTemplate;

Where file.js is a file containing import references to module1 and module2

// file.js

const module1 = require("path-to-module1/module1");
// or
import module2 from "path-to-module2/module2";

API

gulp-mock-module only takes in two parameters

mock(targetModules, mockDirectory);

targetModules

Type: String[]

The names for the modules to replace with a mock.

The names can either be the name of the file itself (module1.js), or the name of the folder containing the index.js that you're importing (module2/index.js)

Note: file extensions are not used in the process so do not include them - the format should be the same as the name you use during the import syntax.

As for the supported file types or the languages of the files - Currently, this is only being used for typescript and javascript files.

["module1", "module2"];

mockDirectory

Type: String

The location of the folder that contains the mocks.

Note: This has not been tested for relative paths, so use path.resolve()

path.resolve(process.cwd(), "src", "mocks");
