Allow passing non interactive options

[italomaia]

It would be quite nice if it was possible to pass the prompt responses from the command line. This way, it would be possible to create a new vue project in a non-interactive way, which is quite convenient for templates that use vue-cli as part of it.

Why do you use vue-cli inside of a template?

[italomaia]

I have a project recipe where vue-cli is used to build the frontend, so, I kind of would like to create the vue project in a non-interactive fashion. My project structure:

project
- app (backend; provides the api)
- ux (vue project)
- web (nginx setup)
other_files

I think that's not the goal of vue-cli. vue-cli is meant to scaffold the whole project. Is there a reason you cannot scaffold the whole project with it?

[italomaia]

Vue Cli would still scaffold. It would just make it possible to do so in a non-interactive way.
Well, I could use vue-cli as the base, but that would probably mean a LOT of work. Not the plan, right now.

Looking for this especially to build docker images where the templates and dependencies are cached.
docker-compose build needs to run non-interactively to make this work.

I had a look at this issue and unfortunately 'commander.js' does not support arbitrary/dynamic options. Hence running a command like the one below is not possible (commander.js#609).
'vue init webpack my-sample-project --build runtime-only --lint standard'

possible solutions:

1. switch from 'commander' to another package like 'yargs' or 'omlette' (similar to raml2html#331)
2. provide options as a config file like vue init webpack my-sample-project --run-with-config default-config.json. Then we can skip the questions for which the values are already available.

If we could agree on the approach, I could give it a shot and submit a PR.

[italomaia]

'yargs' seems like a safe bet.

I was thinking this myself 🤔 to test my template, I run vue init wdmtech/webpack && yarn install && npm run dev and then I have to hit return until the project is scaffolded. I was looking for a:

vue init xxx/xxx . -y (non-interactive) option

if it exists, (or a better damn way of testing my template!) 😂

In the meanwhile you can still use old-good expect to generate your project (for tests as an example):

#!/usr/bin/env expect
set timeout 360

spawn ./node_modules/.bin/vue init . test-project

# This happens because of
# https://github.com/vuejs/vue-cli/issues/291
expect "Project name" { send "\n" }
expect "Project description" { send "\n" }
expect "Project URL" { send "\n" }
expect "Organization" { send "\n" }
expect "vue-cli · Generated" { send "\n" }
