Bootstrap/reset your CouchDB views with pretty JavaScript

pretty-couchdb-views.md

I use this to destroy and create a fresh database for testing. Importing the views this way I can use my favourite editor and have prettify/beautify/linting/hinting on my map-reduce view functions instead of using the Futon editor.

Put all your view functions into:

• data/[designDoc]-[viewName].js (like zdata users-index.js)
• data/index.js (like zdata index.js)

Use something like 0-setup.js to import the views into your CouchDB.

Have fun.

zdata index.js

'use strict';

const fs = require('fs');
const path = require('path');

let contents = [];

fs.readdirSync(__dirname)
  .forEach((fileName) => {
    if (fileName !== 'index.js' && fileName.indexOf('.js') >= 0) {

      let viewContent = require(path.join(__dirname, fileName));

      let viewPath = fileName.split('.')[0].split('-');

      let view = {
        '_id': '_design/' + viewPath[0],
        'language': 'javascript',
        'views': {}
      };

      view.views[viewPath[1]] = viewContent;

      contents.push(view);
    }
  });

module.exports = exports = contents;

zdata users-index.js

module.exports = exports = {
  map: function (doc) {
    if (doc.type === 'user') {
      emit(doc.name, {
        firstName: doc.fistName,
        lastName: doc.lastName
      });
    }
  }
};

ztests 0-setup.js

const config = require('../lib/config.js');
const nano = require('nano')(config.couchdb.host);
const data = require('../couchdb/data');
const db = nano.use('test');
const views = require('../couchdb/views/index.js');

let insertViews = () => {
  let promises = [];
  views.forEach(view => {
    let promise = new Promise((resolve, reject) => {
      db.insert(view, view.id, (error) => {
        if (error) {
          reject(error);
        } else {
          resolve();
        }
      });
    });

    promises.push(promise);
  });

  return Promise.all(promises)
    .then(() => db);
};
