Trusted, Elite Angular. JS Developers for Hire in Oct 2. Angular. JS is the framework of choice for multiple high end web applications. The reason many teams choose this technology is because it is flexible and powerful, seems to evolve in the right direction, has a great community, and has countless extensions and integrations. There are also many Angular developers. While starting out with Angular is fun and building small single page applications is not very difficult, maintaining even a small app can be tough. Until today, a large number of good practices and advanced techniques have been documented and discussed, and some high quality standards have emerged. Our hiring guide will help you find developers who strive to follow that high quality approach. It is the one that results in great applications which attract clients. In this guide, we will cover concepts relevant to scopes, the digest loop, services, testing, and more. Working with Scopes. Template Alfresco Example' title='Template Alfresco Example' />Scopes are the data model of Angular apps. They are the single source of truth in the app, and should be bound and handled with the greatest caution. There are many caveats in dealing with scopes. We will describe a few significant ones below. Q How does scope inheritance work in Angular. JS Describe the various ways for data to be passed into a scope. Scope inheritance in Angular. JS is prototypal for child scopes, but not for isolated scopes. Core directives, which create a new scope, use the child scope option. Those scopes have access to the models set on the parent scope. Accessing parent scope models works seamlessly for objects, but when trying to write to a primitive model e. The model on parent scope will be masked, or shadowed.

The Association for Information and Image Management AIIM International, the worldwide association for enterprisecontent management, defined the term. When building custom directives, it is possible to create an isolated scope. Isolated scopes dont have direct access to their parents models. Still, bindings can be set manually by specifying them in the directives scope property object.

Some of the most common forms are used around Change Request and Document Routing, however OpenContent Forms has been used by our clients for over 400. In such a case, data can be passed into the directive through HTML attributes. That supports both two way and one way bindings, and also expression bindings. Directives also have the ability to transclude scope onto contained elements. When using transclusion manually, it is possible to create a cloned scope one that would keep all the properties of the parents, but would lose all the bindings. That feature is not very well documented. At this point, it seems very important to note that it is possible to traverse scopes, in all directions. Every scope has a parent property null for root scope, and also child. Tail, next. Sibling properties. It is possible to communicate between scopes using those properties, though it may be difficult and also not a good practice. Q What exactly are controllers What is their lifecycle and relation to the scopeControllers are classes, that is, constructor functions, which are bound to a scope AND a section of HTML through the directive ng controller, routing, or through a directive. Setting a controller creates a new scope child scope. The controllers purpose is to set up the initial state of the scope and also manipulate it by adding behaviour, setting watches, event listeners, etc. Even though at first controllers may seem like the primary ground of operation in Angular. JS, once the developer truly understands the purpose of scopes in Angular. JS, their use of controllers will minify. It is not optimal to perform calculations directly on scope models, as those might be watched, and in effect may trigger and slow down the digest phase. The motto that transcends MVC frameworks keep controllers thin applies very well to Angular. JS. Controllers are bound to their scope, and so is their lifecycle. Once a new scope is created, the compile service sets up initial watches on the scope. At that point, the scope can be manipulated, models on the scope can be created, mutated or destroyed, new watches and listeners can be set. For the changes to take effect, a digest phase needs to be triggered. That allows for observing and responding to model mutation which is a reaction, thus the next step. The scopes lifecycle ends with its destruction. Additional events are fired on that occasion. This usually is also the end of the interest for the controller, though it may live on as Java. Script closures do. Q Please explain what. Angular. JS. eval is a simple scope method which takes an expression and optionally locals and then executes it against the current scope, using parse. The service parse is where the magic happens. It takes an Angular expression and returns a function, which takes two arguments context and locals. The latter is used for overriding variables set in the context. The context is the key part. A good helper question to this one would be did you, the developer, ever wonder why core Angular directives take only the model name set on the scope E. Sets the value of scope model foo to 5lt button. In the directive, the scope object is implicit. What really happens the expression passed to ng click is parsed, which returns a function, which is then executed with the current scope passed in as context. Fn parsefoo 5. Fnscope. There are many use cases for parse, as it is a really great service. A particularly useful one is to check for deep nested properties of objects when there is no assurance that at any level the property is not null. If one would try to access quux directly, Java. Script would throw an exception. Another more specific use case is to allow users to declare variables and assign values to them, such as in text input fields, and then reuse the variables in other input fields and more. An example of that might be a calculator or notepad application. To keep it safe, scope could be used as the context for the variables. Working with the Digest Loop. The digest loop is used to keep the DOM in sync with the models set on the scope. In Angular, running into issues around the digest cycle is common. A deep understanding of the digest cycle is much less common. The developer being interviewed should be familiar with what the digest cycle is and how it works. The requirement for that knowledge will emerge sooner than later when building a large application. The questions below will help you assess their level of proficiency. Q How does Angular. JS know when to perform dirty checking and update DOM output The answer is short when it is told to do so. The point is, there is no polling mechanism that would trigger dirty checking automatically. Core Angular. JS directives, services, and methods usually set up watches, or fire the digest cycle explicitly. That process is executed internally, it is not exposed, and may not be obvious to the developers. In fact, there are articles which contradict the facts, falsely stating that there is a constant heartbeat in Angular. JS. There is no such thing. Manipulating scope models using non core functionality requires the developers to manually trigger the digest cycle. In most cases, that is done by using the scope method. That phase propagates down to every child scope. Without anything triggering digest, the dirty checking will not happen. The callbacks to watches will not be fired, and DOM output will not be updated. Q What is the difference between. Enterprise content management Wikipedia. Enterprise content management ECM is a formalized means of organizing and storing an organizations documents, and other content, that relate to the organizations processes. The term encompasses strategies, methods, and tools used throughout the lifecycle of the content. DefinitioneditThe Association for Information and Image Management AIIM International, the worldwide association for enterprise content management, defined the term in 2. AIIM has refined the abbreviation ECM several times to reflect the expanding scope and importance of information management Late 2. Enterprise content management is the technology used to capture, manage, store, preserve, and deliver content and documents related to organizational processes. Early 2. 00. 6Enterprise content management is the technology used to capture, manage, store, preserve, and deliver content and documents related to organizational processes. ECM tools and strategies allow the management of an organizations unstructured information, wherever that information exists. Early 2. 00. 8Enterprise Content Management ECM is the strategies, methods, and tools used to capture, manage, store, preserve, and deliver content and documents related to organizational processes. ECM tools and strategies allow the management of an organizations unstructured information, wherever that information exists. Early 2. Enterprise Content Management ECM is the strategies, methods, and tools used to capture, manage, store, preserve, and deliver content and documents related to organizational processes. ECM covers the management of information within the entire scope of an enterprise whether that information is in the form of a paper document, an electronic file, a database print stream, or even an email. March 2. AIIM retired the term ECM in favor of a more encompassing term, Intelligent Information Management IIM. IIM is defined as the strategies, methods, and tools used to create, capture, automate, deliver, secure, and analyze content and documents related to organizational processes. IIM refers to the management of content AND data, not just content itself. The latest definition encompasses areas that have traditionally been addressed by records management and by document management systems. It also implies the conversion of data between various digital and traditional forms, including paper and microfilm. ECM as an umbrella term covers document management, Web content management, search, collaboration, records management, digital asset management DAM, workflow management, capture and scanning. ECM is primarily aimedby whom at managing the life cycle of information from initial publication or creation all the way through archival and eventual disposal. ECM applications are deliveredby whom in four ways on premises software installed on an organizations own networksoftware as a service Saa. S Web access to information that is stored on a software manufacturers systema hybrid composed of both on premises and Saa. S components. Infrastructure as a Service Iaa. S which refers to online services that abstract the user from the details of infrastructure like physical computing resources, location, data partitioning, scaling, security, backup etc. ECM aims to make the management of corporate information easier through simplifying storage, security, version control, process routing, and retention. The benefits to an organization include improved efficiency, better control, and reduced costs. For example, many banks have converted to storing copies of old cheques within ECM systems ECMSs as opposed to the older method of keeping physical cheques in massive paper warehouses. Under the old system, a customer request for a copy of a cheque might take weeks, as the bank employees had to contact the warehouse where the right box, file, and cheque, would need to be located. The cheque would then need to be pulled, a copy made and mailed to the bank where it would finally be mailed to the customer. With a suitable ECM system in place, the bank employee might simply query the system for the customers account number and the number of the requested cheque. When the image of the cheque appears on screen, the bank can mail a copy immediately to the customer, usually while the customer is still on the phone. Enterprise content management, as a form of content management, combines the capture, search and networking of documents with digital archiving, document management and workflow. It specifically includes the special challenges involved in using and preserving a companys internal, often unstructured information, in all of its forms. Therefore, most ECM solutions focus on business to employee B2. E systems. As ECM solutions have evolved, new components have emerged. For example, as content is checked in and out, each use generates new metadata about the content, to some extent automatically information about how and when people use the content can allow the system to gradually acquire new filtering, routing and search pathways, corporate taxonomies and semantic networks, and retention rule decisions. Email and instant messaging feature increasingly in decision making processes ECM can provide access to data about these communications, which can be usedby whom in business decisions. Solutions can provide intranet services to employees B2. E, and can also include enterprise portals for business to business B2. B, business to government B2. G, government to business G2. B, or other business relationships. This category includes most former document management groupware and workflow solutions that have not yetupdate fully converted their architecture to ECM, but provide a Web interface. Digital asset management is a form of ECM concerned with content stored using digital technology. HistoryeditThe technologies that comprise ECM as of 2. EDMS of the late 1. The original EDMS products were stand alone products, providing functionality in one of four areas imaging, workflow, document management, or ERM see components below. The typical early EDMS adopter deployed a small scale imaging and workflow system, possibly to just a single department, in order to improve a paper intensive process and to migrate towards the mythical paperless office. The first stand alone EDMS technologies aimed to save time or to improve information access by reducing paper handling and paper storage, thereby reducing document loss and providing faster access to information. EDMS could provide online access to information formerly available only on paper, microfilm, or microfiche. By improving control over documents and document oriented processes, EDMS streamlined time consuming business practices. The audit trail generated by EDMS enhanced document security and provided metrics to help measure productivity and identify efficiencies. Through the late 1. EDMS industry continued to grow steadily. As more organizations achieved pockets of productivity with these technologies, it became clear that the various EDMS product categories were complementary. Organizations increasingly wanted to leverage multiple EDMS products. Consider, for example, a customer service departmentwhere imaging, document management, and workflow could combine to allow agentsdisambiguation needed to better resolve customer inquiries.
