pouchdb-observe v0.0.3

PouchDB Observer Plugin

Building

npm install
npm run build

Your plugin is now located at dist/pouchdb.mypluginname.js and dist/pouchdb.mypluginname.min.js and is ready for distribution.

Getting Started

First, change the name in package.json to whatever you want to call your plugin. Change the build script so that it writes to the desired filename (e.g. pouchdb.mypluginname.js). Also, change the authors, description, git repo, etc.

Next, modify the index.js to do whatever you want your plugin to do. Right now it just adds a pouch.sayHello() function that says hello:

exports.sayHello = utils.toPromise(function (callback) {
  callback(null, 'hello');
});

Optionally, you can add some tests in tests/test.js. These tests will be run both in the local database and a remote CouchDB, which is expected to be running at localhost:5984 in "Admin party" mode.

The sample test is:

it('should say hello', function () {
  return db.sayHello().then(function (response) {
    response.should.equal('hello');
  });
});

Testing

In Node

This will run the tests in Node using LevelDB:

npm test

You can also check for 100% code coverage using:

npm run coverage

If you don't like the coverage results, change the values from 100 to something else in package.json, or add /*istanbul ignore */ comments.

If you have mocha installed globally you can run single test with:

TEST_DB=local mocha --reporter spec --grep search_phrase

The TEST_DB environment variable specifies the database that PouchDB should use (see package.json).

In the browser

Run npm run dev and then point your favorite browser to http://127.0.0.1:8001/test/index.html.

The query param ?grep=mysearch will search for tests matching mysearch.

Automated browser tests

You can run e.g.

CLIENT=selenium:firefox npm test
CLIENT=selenium:phantomjs npm test

This will run the tests automatically and the process will exit with a 0 or a 1 when it's done. Firefox uses IndexedDB, and PhantomJS uses WebSQL.

What to tell your users

Below is some boilerplate you can use for when you want a real README for your users.

To use this plugin, include it after pouchdb.js in your HTML page:

<script src="pouchdb.js"></script>
<script src="pouchdb.mypluginname.js"></script>

Or to use it in Node.js, just npm install it:

npm install pouchdb-myplugin

And then attach it to the PouchDB object:

var PouchDB = require('pouchdb');
PouchDB.plugin(require('pouchdb-myplugin'));
