couchdb-mkdb

couchdb-mkdb makes it easy to create databases and stream couchdb's response.

Installation

$ npm i -S couchdb-mkdb

Usage

Express example

This express route creates new databases on every request.

...
app.post('/', (req, res, next) => {
  let name = 'mydb-' + uuid.v1();
  let opts = {

    // `security` is a special option ...
    security: {
      admins: {names: [req.user.name], roles: []},
      members: {names: [], roles: []}
    },

    // ... all other options are passed to the underlaying `request` function.
    // See https://github.com/request/request#requestoptions-callback
    baseUrl: app.get('couchdb'),
    auth: app.get('auth')
  };

  // Use the mkdb utility to create the database
  mkdb(name, opts)
    .on('error', next)
    .on('response', function(response) {

      // For error handling check the statusCode
      if ((response.statusCode / 100 | 0) !== 2) {
        console.log('Database wasn\'t created or security couldn\'t be updated');
      }
      response.pipe(
        res.set(response.headers)
          .status(response.statusCode)
      );
    })
    .on('success', function() {

      // Event 'response' has already been emitted
      console.log('Database successfully created');
    });
});

API

mkdb(name, [opts], callback)

• name The name of the database
• opts Optional options object. See below
• callback Function with the signature fn(error, response)

Available options are:

• security The security rules to apply to the database. See Couchdb security

All other options are passed to the underlaying request() function.

Events

• error(err) - Emitted on request error
• errorResponse(res) - deprecated Emitted when couchdb returns a paranormal response. See Update notes
• response(res) - Emitted when couchdb responds to the last action
• success - Emitted on success

Tests

$ git clone https://github.com/domachine/node-couchdb-mkdb.git
$ cd node-couchdb-mkdb
$ npm i
$ npm test

Update notes

v2.0

mkdb now uses request as transport engine. Therefore the options you can pass are similar to request's options. See docs.

v1.1

The first version had an 'errorResponse' event. This has now been deprecated. Use the 'response' event instead and check the statusCode.
