google-apps-script-template

This repository is intended to be a starting point for javascript projects used in scriptable Google Cloud Apps. It tries to solve the most common tasks when creating and maintaining code for the Google Apps Script environment.

Usage

1. Install all global and local npm dependencies

   npm install -g @google/clasp [email protected]
   npm install
   

2. If you haven't done yet, log in to clasp and follow the steps

   clasp login
   

3. Init a project

   # Use the init task to create a new clasp project
   gulp init --project-dir="projects/example"
   
   # Or clone an existing project by providing a script id
   gulp init --project-dir="projects/example" --script-id="{scriptId}"
   
   

4. You're ready to go! You can build or watch a project or execute a sub task (see next section). These are the most common tasks you will likely use:

   # Build a project:
   gulp build --project-dir="projects/example"
   
   # Build all projects
   gulp build:all
   
   # Watch a project
   gulp watch --project-dir="projects/example"
   
   # Watch all projects
   gulp watch:all
   

Tasks

General infos

Task arguments

Most tasks need a --project-dir argument to work properly. It defines, on which project the task is being executed.

About {task}:all tasks

Some tasks have an additional flavour to execute them on all currently registered projects. All projects that are created with gulp init are added automatically to this list located at gulp/config/projects.json.

Build

Build one

Compile a single project and push the distribution files via clasp cli
Example: gulp build --project-dir="projects/example"

Build all

Execute the build step for all registered projects.
Example: gulp build:all

Push

Update the remote files with the distribution files
Example: gulp clasp-push --project-dir="projects/example"

Clean

Remove the files that have been produced by other tasks
Example: gulp clean --project-dir="projects/example"

Clean js files

Remove only the files that have been created by the compile-js task
Example: gulp clean:compileJs --project-dir="projects/example"

Clean copied files

Remove only the files that have been created by the copy task.
Example: gulp clean:copy --project-dir="projects/example"

Copy

Copy over config files like .claspignore or appsscript.json
Example: gulp copy --project-dir="projects/example"

Lint js files

Lint project files with eslint
Example: gulp lint-js --project-dir="projects/example"

Initiate a new project

Create a new clasp project
Example: gulp init --project-dir="projects/example"

Initiate an existing project

Create a clasp project from an existing remote source
Example: gulp init --project-dir="projects/example" --script-id="{scriptId}"

Watch

Watch one

Watch a single project folder and recompile/push on changes
Example: gulp watch --project-dir="projects/example"

Watch all

Watch all project folders
Example: gulp watch:all

Features

Clasp

Manage your GAS code locally in the dev environment you need to be productive!

Babel

Code is being transpiled via babel so you can write es20XX and not think about the consequences.

Webpack

GAS code is global by default. As javascript developers are terrible at modules and stuff, this problem has been solved by webpack long ago, so that you can organize your code with module.export and require

Eslint

There is a ton of stuff that you can and will write wrong. eslint is there to help and annoy you to death.

Core-js

As you might know, GAS code is ES3 enhanced with random features from the generations afterwards. It's not that horrible, but annoying enough to be annoyed. This template provides core-js as a module and a polyfill entry point.
Adding a polyfill is as easy as adding a line of javascript: require('core-js/modules/es6.array.is-array');
