backbone-orm

BackboneORM was designed to provide a consistent, polystore ORM across Node.js and the browser.

It was inspired by other great software and provides:

• Node.js-style callbacks and streams for a familiar asynchronous programming style
• MongoDB-like query language to easily slice-and-dice your data
• a REST controller enabling browser search bar queries and an optional paging format like CouchDB

Other great things:

• it provides a JSON-rendering DSL
• it solves the dreaded Node.js circular dependencies problem for related models
• it is compatible with Knockback.js
• it parses ISO8601 dates automatically
• BackboneMongo provides a CouchDB-like '_rev' versioning solution
• BackboneREST provides authorization middleware hooks and emits REST events

Examples (CoffeeScript)

# Find the Project with id = 123
Project.findOne {id: 123}, (err, project) ->

# Find the first Project named 'my kickass project'
Project.findOne {name: 'my kickass project'}, (err, project) ->

# Find all items with is_active = true
Project.find {is_active: true}, (err, projects) ->

# Find the items with an id of 1, 2 or 3
Project.find {id: {$in: [1, 2, 3]}}, (err, projects) ->

# A shortcut for `$in` when we're working with ids
Project.find {$ids: [1, 2, 3]}, (err, projects) ->

# Find active items in pages
Project.find {is_active: true, $limit: 10, $offset: 20}, (err, projects) ->

# Select named properties from each model
Project.find {$select: ['created_at', 'name']}, (err, array_of_json) ->

# Select values in the specified order
Project.find {$values: ['created_at', 'status']}, (err, array_of_arrays) ->

# Find active items in pages using cursor syntax (Models or JSON)
Project.cursor({is_active: true}).limit(10).offset(20).toModels (err, projects) ->
Project.cursor({is_active: true}).limit(10).offset(20).toJSON (err, projects_json) ->

# Find completed tasks in a project
project.cursor('tasks', {status: 'completed'}).sort('name').toModels (err, tasks) ->

# Iterate through all items with is_active = true in batches of 200
Project.each {is_active: true, $each: {fetch: 200}},
  ((project, callback) -> console.log "project: #{project.get('name')}"; callback()),
  (err) -> console.log 'Done'

# Stream all items with is_active = true in batches of 200
Project.stream({is_active: true, $each: {fetch: 200}})
  .pipe(new ModelStringifier())
  .on('finish', -> console.log 'Done')

# Collect the status of tasks over days
stats = []
Task.interval {$interval: {key: 'created_at', type: 'days', length: 1}},
  ((query, info, callback) ->
    histogram = new Histogram()
    Task.stream(_.extend(query, {$select: ['created_at', 'status']}))
      .pipe(histogram)
      .on('finish', -> stats.push(histogram.summary()); callback())
  ),
  (err) -> console.log 'Done'

Examples (JavaScript)

// Find the Project with id = 123
Project.findOne({id: 123}, function(err, project) {});

// Find the first Project named 'my kickass project'
Project.findOne({name: 'my kickass project'}, function(err, project) {});

// Find all items with is_active = true
Project.find({is_active: true}, function(err, projects) {});

// Find the items with an id of 1, 2 or 3
Project.find({id: {$in: [1, 2, 3]}}, function(err, projects) {});

// A shortcut for `$in` when we're working with ids
Project.find({$ids: [1, 2, 3]}, function(err, projects) {});

// Find all items with is_active = true
Project.find({is_active: true, $limit: 10, $offset: 20}, function(err, projects) {});

// Select named properties from each model
Project.find({$select: ['created_at', 'name']}, function(err, array_of_json) {});

// Select values in the specified order
Project.find({$values: ['created_at', 'status']}, function(err, array_of_arrays) {});

// Find active items in pages using cursor syntax (Models or JSON)
Project.cursor({is_active: true}).limit(10).offset(20).toModels function(err, projects) {});
Project.cursor({is_active: true}).limit(10).offset(20).toJSON function(err, projects_json) {});

// Find completed tasks in a project sorted by name
project.cursor('tasks', {status: 'completed'}).sort('name').toModels function(err, tasks) {});

// Iterate through all items with is_active = true in batches of 200
Project.each({is_active: true, $each: {fetch: 200}},
  function(project, callback) {console.log('project: ' + project.get('name')); callback()},
  function(err) {return console.log('Done');}
);

// Stream all items with is_active = true in batches of 200
Project.stream({is_active: true, $each: {fetch: 200}})
  .pipe(new ModelStringifier())
  .on('finish', function() {return console.log('Done');});

var stats = [];
Task.interval({$interval: {key: 'created_at', type: 'days', length: 1}},
  function(query, info, callback) {
    var histogram = new Histogram()
    Task.stream(_.extend(query, {$select: ['created_at', 'status']}))
      .pipe(histogram)
      .on('finish', function() {stats.push(histogram.summary()); return callback();});
