How can i append the data to an existing JSON file?

[talvasconcelos]

Hi, how can i append the data i get from front-matter to an existing json file? Here's what i have:

`gulp.task('meta', function(){ return gulp.src(path.posts) .pipe(plumber({ handleError: onError })) .pipe(frontMatter({ property: 'meta'})) //.pipe(data(function(file){ // file.meta.path = file.path // })) .pipe(pluck('meta', 'meta.json')) .pipe(data(function(file){ file.contents = new Buffer(JSON.stringify({'articles': file.meta}, null, ' ')); //var obj = JSON.parse(require './config.json'); //obj.articles = file.contents;

}))
.pipe(gulp.dest('dev/articles/'))

});`

At the moment it outputs to a meta.json file, i'd like for it to append the data to an existing config.json under an "artilcles" key.

Thanks, Tiago

This is from my project and works well.

1. Append static json
2. Append currFile
3. Append GrayMatter Data (works same as FrontMatter)

      .pipe(plugins.data(function (file) {
        let data = JSON.parse(fs.readFileSync(cacheFile));
        data.currFile = path.basename(file.path);
        return data;
      }))
      .pipe(plugins.grayMatter())
