What is this?

A NodeJS library to talk to Target Process 3's API.

How do I use it?

In your NodeJS program, add:

var tp = require('tp-api')({
           domain:   // your domain here; eg: 'fullscreen.tpondemand.com'
           username: // your username; eg: '[email protected]'
           password: // your password
           version:  // Optional API version - defaults to 1
           protocol: // Optional protocol - defaults to https
         })

tp('Tasks')
  .take(5)
  .where("EntityState.Name eq 'Open'")
  .pluck('Name', 'NumericPriority')
  .sortBy('NumericPriority')
  .then(function(err, tasks) {
    console.log('my tasks', tasks)
  }
)

Methods

tp() or tp([Entity name])

Returns a TargetProcess request object. Can optionally set an entity to request.

tp.get(Entity Name)

Tells the TargetProcess object to request the given entity. An entity can be one of the following:

• Context
• Projects
• Features
• Releases
• Iterations
• Requests
• CustomFields
• Bugs
• Tasks
• TestCases
• Times
• Impediments
• Assignments
• Attachments
• Comments
• UserStories
• Roles
• GeneralUsers
• EntityStates

Example - fetch a list of roles

tp('Roles').then(function(err, roles) { ... })

tp.take(n)

Tells the TargetProcess object to request n of the requested entities

Example - fetch 5 tasks:

tp('Tasks').take(5).then(function(err, tasks) { ... })

tp.context(acid)

Retrieve list of entities for specific projects (via Acid)

Example - fetch 5 tasks of the project with the context 123456:

tp('Tasks').take(5).context(123456).then(function(err, tasks) { ... })

tp.where(search expression)

Applies a search filter to the TargetProcess request.

Example, find open tasks:

tp('Tasks').where("EntityState.Name eq 'Open'").then(function(err, tasks) { ... })

More info on Target Process filters can be found here: https://dev.targetprocess.com/docs/sorting-and-filters

tp.pluck(list, of, properties)

Instructs the Target Process object to only include the listed properties in the response object:

Example, fetch the name and description from these tasks:

tp('Tasks').pluck('Name', 'Description').then(function(err, tasks) { ... })

tp.sortBy(field)

Tells the Target Process request to sort on the given field

Example, fetch a list of tasks by priority:

tp('Tasks').sortBy('NumericPriority').then(function(err, tasks) { ... })

or sort by descending order:

tp('Tasks').sortByDesc('NumericPriority').then(function(err, tasks) { ... })

tp.append(list, of, properties)

Instructs the Target Process request to get additional information about Entity

Example, get number of bugs, tasks and comments associated with those user stories:

tp('UserStories').append('Bugs-Count, Tasks-Count, Comments-Count')
.then(function(err, stories) { ... })

tp.then(handlerFunction)

Executes the Target Process request. Your callback will be called with an error object and the result of your request.

Example, fetch a list of tasks:

tp('Tasks').then(function(err, tasks) {
  console.log('My tasks', tasks)
  console.error('Errors from the request', err)
})

tp.thenEntities(handlerFunction)

Thin wrapper around tp.then, but instead of returning (err, data) it returns (err, entities) where entities is an array of entity objects.

Example, fetch a list of Entities

// Move all open tasks to 'Planned'
tp('Tasks').
  where("EntityState.Name eq 'Open'").
  then(function(err, tasks) {
  tasks.forEach(function(entity){
    entity.setState('Planned')
  })
})

Nested JSON objects

It may happen that the following code:

tp('Tasks')
  .take(1)
  .pluck('CustomFields')
  .then(function(err, tasks) {
    console.log('my tasks', tasks)
  }
)

will return a lot of nested JSON objects:

my tasks [ { ResourceType: 'Task',
    Id: 3631,
    Project: { ResourceType: 'Project', Id: 4026, Process: [Object] },
    CustomFields: [ [Object], [Object], [Object], [Object], [Object] ] } ]

The returned object tasks here is a JavaScript object. In order to convert it into JSON string, use JSON.stringify():

tp('Tasks')
  .take(1)
  .pluck('CustomFields')
  .then(function(err, tasks) {
    console.log('my tasks', JSON.stringify(tasks))  // changed here
  }
)

and now it returns:

my tasks [{"ResourceType":"Task","Id":3631,"Project":{"ResourceType":"Project","Id":4026,"Process":{"Id":5,"Name":"AIScrum"}},"CustomFields":[{"Name":"Component","Type":"DropDown","Value":null},{"Name":"trac","Type":"Number","Value":null},{"Name":"Job","Type":"DropDown","Value":null},{"Name":"Resolution","Type":"DropDown","Value":null},{"Name":"Domain","Type":"DropDown","Value":null}]}]
