Use prompt without pipe

[renanhenrique]

Hi, take a look @ this code:

gulp.task('install', function(){
  gulp.src('config/db.js')
  .pipe(
    gp_prompt.prompt(
      { type: 'input'
      , name: 'dbname'
      , message: 'Type your DB name:'
      },
      function (res){
        gulp.src('config./db.js')
        .pipe(gp_replace('_DBNAME_', res.dbname))
        .pipe(savefile())
      }
    )
  )
});

There's a way to use gulp-prompt without open 2 gulp.src('config/db.js') ?

I think that this Is not posible.
I use gulp.src('package.json') but it is ugly and slowing down the init.

I haven't really investigated why this works, but if you call .write() on the prompt stream, it will work:

gulp.task('install', function(){
  var prompter = gp_prompt.prompt(
    { type: 'input'
    , name: 'dbname'
    , message: 'Type your DB name:'
    },
    function (res){
      gulp.src('config./db.js')
      .pipe(gp_replace('_DBNAME_', res.dbname))
      .pipe(savefile())
    }
  )

  prompter.write()
  return prompter()
});

This probably has something to do with gulp not liking the Stream that Inquirer is returning

I miss this feature too.

I tried a confirm question with write(), @codyrushing . It didn't work as expected for me. The task was finished and then the question shown up.

Solved with Inquirer.js which is the library used by gulp-prompt

Example:

Both stop the gulp execution when the answer is 'no'.

//gulp-prompt
gulp.task('prompt', () => {
  const question = {
    message : 'Do you want to continue?(no)',
    default : false
  };

  return gulp.src('file')
    .pipe(prompt.confirm(question));
});

//Inquirer.js
gulp.task('prompt', () => {
  const question = [
    {
      type : 'confirm',
      name : 'continue',
      message : 'Do you want to continue?(no)',
      default : false
    }
  ];

  return inquirer.prompt(question).then(answer => {
    if (!answer.continue) {
      return process.exit (2);
    }
  });
});

I am going to close this issue out since yuricamara seems to have provided a solution. If there is still any outstanding questions or concerns please let me know.
