海外TECH	DEV Community	What methods were used for software development prior to DevOps.	https://dev.to/abhixsh/what-methods-were-used-for-software-development-prior-to-devops-98f	What methods were used for software development prior to DevOps Software development used to be based on old methods like Waterfall or Spiral before DevOps These methods emphasized a sequential phased approach for software development with distinct stages for requirements gathering and design development testing deployment and testing These traditional methods did not place enough emphasis on automation and continuous delivery This led to slow and inconsistent software deployments There was also a lack in communication and collaboration between operations and development teams This led to a lackluster alignment and slow responses to changing customer requirements This limitation of traditional methods led to the creation of Agile and Lean alternative methodologies which emphasize collaboration flexibility and continuous improvement These methodologies were an improvement on traditional methods but they did not address the need to seamlessly integrate development and operations teams DevOps was created to address these issues It advocates for a more collaborative agile and unified approach to software development which integrates operations and development into one consistent process This has been widely adopted and allows organizations to quickly respond to customer changes and compete in digital first markets Waterfall ModelThe Waterfall model a sequential and traditional method of software development was popular before Agile and DevOps Software development can be broken down into stages according to the Waterfall model Each stage must be completed before the next stage starts These stages usually include Analysis and gathering of requirementsDesignImplementationTestDeploymentMaintenanceThe waterfall model is a simple linear approach to software development This model follows a top down approach This model begins with gathering and analysing requirements This stage is where you get the client s requirements in order to create an application These needs are then analysed When you create a software program plan the following stages are available This is how your software will look at this stage Once the design is completed you move to the Implementation stage where you begin writing the code for the application A group of programmers works together on each part of the application After the application is created it s time to verify it You will run a variety of tests on the application including integration testing and unit testing After passing all its tests the program is installed on production servers Finally the Maintenance phase is here During this stage the application s performance is monitored This stage fixes any issues with the functionality of the application It is often difficult to make changes to the requirements once development has started This makes the Waterfall model less suited for projects that are rapidly changing or have complex requirements The Waterfall model can still be used in certain situations despite its limitations This is especially true for projects that have well defined requirements and high predictability The Waterfall model is now largely obsolete for most software development projects Agile and DevOps are more flexible and agile Waterfall models offer the following benefits A well structured and clearly defined process The Waterfall Model provides a well defined sequential process that is easy to follow and understand It is well suited to projects that have well defined requirements and high levels of predictability Waterfall is a great choice for documentation It emphasizes planning and documentation making it an excellent choice for projects that need a lot of documentation Predictable schedule Because of its sequential nature the Waterfall model can accurately predict the timeline and schedule of a project This makes it an excellent choice for projects that have fixed deadlines High degree of control The Waterfall Model provides high levels of control over the software development process This allows managers to monitor progress and keep the project on track It is simple to manage The Waterfall process is straightforward to follow and understand It is a great choice for large teams and complex organizational structures Waterfall s problems include Inflexibility It is difficult to adapt to changes in the Waterfall model s sequential nature once it has been developed This can cause delays cost overruns dissatisfaction and even lead to lawsuits Poor adaption to change The Waterfall Model was not designed for projects that have well defined stable requirements It is therefore unsuitable for projects that are constantly changing Lack of customer involvement Waterfall models tend to emphasize documentation and planning Customers are not allowed to participate in these areas This can cause misunderstandings and make it difficult to align development and customer needs High chance of errors Waterfall models can be susceptible to errors because there is not much time to correct errors until the end of development Limited collaboration Waterfall models often result in a lackluster collaboration between operations and development teams This can lead to poor alignment and slow responses to changing customer requirements Inefficient use resources Due to the sequential nature of Waterfall development efforts can be conducted in parallel and resources may not be used efficiently Agile MethodologyAgile methodology refers to a set principles and practices that promote collaboration flexibility and continuous improvement in software development Agile methodology is based upon the Agile Manifesto which was published for the first time in Software development follows Agile methodology Iterative and incremental software development emphasizes small usable frequent increments of functionality This approach encourages communication and collaboration between the development and customer teams and encourages regular feedback to adjust requirements according to changing conditions Agile methodology is defined by several key practices such as Iterative and incremental developmentsCollaboration and cross functional team buildingSoftware is delivered regularly and frequently Feedback and involvement from customersFlexibility and adaptability to changesConstant improvement and reflectionAgile methodology is used in a wide range of software development contexts It has quickly become one of the most effective and popular approaches to software development This methodology has proven to be particularly effective in enabling organizations respond quickly to changing customer requirements and deliver software more consistently than other methodologies like Waterfall Each iteration follows the waterfall method and includes steps such as requirements gathering planning testing programming maintenance and testing Each repetition takes between and weeks Agile Method A business launches an app with some high priority functionality during its first iteration of agile End users or consumers can comment on the functionality of the application after it is released After any modifications have been made to the application the second version of the application will be released You must continue the process until you achieve the desired software quality Agile methodology offers many benefits Accelerated delivery of value Agile methodology emphasizes small usable frequent increments of functionality This allows organizations to respond faster to changing customer requirements and deliver value quicker Collaboration and communication are increased Agile methodology encourages collaboration between customer and development teams This allows organizations to align their development efforts with customer requirements and receive feedback on the development process Increased adaptability flexibility and adaptability Agile methodology allows organizations to adapt to changing market conditions and requirements more efficiently Software that is more quality Agile methodologies emphasize regular testing and delivery software This allows organizations to quickly identify and fix problems in their development processes which leads to better software Improved alignment with business goals The Agile methodology allows organizations to align their development efforts with business objectives by prioritizing and delivering most valuable features and functionalities first Increased team morale motivation and collaboration The Agile methodology emphasizes teamwork and collaboration This can lead to improved team morale Customer satisfaction is increased The agile methodology allows organizations to deliver software that meets customers needs better which leads to higher customer satisfaction These are the problems with Agile methodology Lack of detail planning Agile methodology emphasizes flexibility and adaptability This can lead to a lack or detailed planning as well as difficulty managing large or complex projects Potential for scope creep Agile methodology s flexible nature can lead to scope creep when new requirements and changes are made to the project in development Limited documentation The Agile methodology places emphasis on working software over documentation This can result in a lack of documentation and difficulty managing long term software projects Estimating time and budget can be difficult Due to the iterative nature Agile methodology it can be difficult to accurately estimate time or budget for a project This can lead to difficulties in project management Teams must be skilled and experienced Agile methodologies require a high level of collaboration communication and teamwork This can prove difficult for teams who aren t skilled or experienced in these areas Limited visibility into progress Although Agile methodology encourages regular delivery and maintenance of software it can be difficult to see the progress of large or complex projects Potential for misunderstandings Although Agile methodology encourages collaboration and regular communication it can also lead to misunderstandings when not properly implemented my previous article about DevOps

海外TECH	DEV Community	Label htmlFor Property Explained	https://dev.to/lavary/label-htmlfor-property-explained-1pjd	Label htmlFor Property ExplainedUpdate This post was originally published on my blog decodingweb dev where you can read the latest version for a user experience rezaWe use the HTML lt label gt element to caption form elements such as a text box checkbox radio button etc To do so all you need to do is to set the label s for attribute with the ID string of its corresponding form element this means your form element should already have an ID attribute Something like this lt label for usernameId gt Username lt label gt lt input type text name username id usernameId gt Labelling form elements have multiple accessibility advantages Assistive technologies It makes the label and the form element programmatically related For instance a screen reader would read out the form element s label to visually impaired users Accessibility and UX It also increases the hit area when interacting with a form element click or touch For instance when you click the label of a text box it ll gain focus so you can start typing Or if it s a checkbox or a radio button it ll be checked a pleasant experience on small screen devices Here s an example lt section gt lt label for usernameControl gt Username lt label gt lt input type text name username id usernameControl gt lt section gt lt section gt lt input type checkbox id checkControl gt lt label for checkControl gt Click me lt label gt lt section gt lt section gt lt input type radio name radioControl id radioControl gt lt label for radioControl gt Option lt label gt lt input type radio name radioControl id radioControl gt lt label for radioControl gt Option lt label gt lt input type radio name radioControl id radioControl gt lt label for radioControl gt Option lt label gt lt section gt But sometimes you might need to manage set or get a label s for property dynamically from your JavaScript code In this quick guide I ll explain how you can programmatically manage the for attribute with the help of the Label htmlFor property via JavaScript How to use the Label htmlFor propertyThe HTMLLabelElement htmlFor lets you read the for attribute s current value It also allows you to set its value on the fly Let s start with a quick example for those friends who need a short snippet for today Then we ll get to the details Let s imagine we have the following form control lt label for usernameId gt Username lt label gt lt input type text name username id usernameId gt To read the value of the for attribute you can access its htmlFor property in the DOM like so Get the DOM element by Idlet label document querySelector usernameLabel Access the htmlFor propertylet forValue label htmlForAnd if you need to set the for value programmatically at runtime Get the DOM element by Idlet labelElement document querySelector usernameLabel Set the for attribute value via htmlFor propertylabelElement htmlFor someValue In the above example someValue is the ID string of the form control to which the label is associated Please note when a label is implicitly associated with a form control by placing the form element within the label tag this property would return an empty value lt label gt Username lt input type text gt lt label gt Can t we just use setAttribute getAttribute Since the htmlFor property reflects the value of the for attribute technically it s possible to use setAttribute to set the for attribute of a label let labelElement document querySelector usernameLabel let forValue labelElement setAttribute for someValue However Mozilla recommends using htmlFor whenever you need to set the for attribute programmatically Label htmlFor property is well supported across most web Wrapping upThe for attribute helps you add interactive behavior to a web page without writing a single line of JavaScript For instance to create custom checkbox radio button elements or even trigger a popup or a sliding menu However if you need more control over your labels from javaScript code label s htmlFor is the property you ll need I hope this quick guide can provide an answer to your question Thanks for reading	2023-02-06 20:15:44
海外TECH	DEV Community	About “ReferenceError: document is not defined” in JavaScript	https://dev.to/lavary/about-referenceerror-document-is-not-defined-in-javascript-1h3g	About “ReferenceError document is not defined in JavaScriptUpdate This post was originally published on my blog decodingweb dev where you can read the latest version for a user experience rezaThis guide explains why ReferenceError document is not defined occurs and how you can fix it let element document querySelector usernameLabel ReferenceError document is not definedThe most common reason for document is not defined error is that your JavaScript code is trying to access the document object in a non browser environment such as Node js A quick intro to the document object Whenever you access a web page via the web browser the browser s renderer fetches and parses the HTML code along with the assets and stores its elements headings paragraphs images form elements etc into an internal data structure called DOM Document Object Model DOM is then turned into Render Tree consisting of visible elements and their styles and through a complicated process the code is turned into pixels what you see as a user Additionally the web browser exposes an interface to the DOM tree called DOM API The DOM API lets you modify the page programmatically via JavaScript to do things like Set the page title on the flyAdd remove HTML element s Manage CSS stylesAdd remove CSS classesand a lot more And the entry point to this powerful API is the document object What causes ReferenceError document is not definedThe first thing to know is that the DOM API is a web browser component and not a part of JavaScript JavaScript only enables you access this object like any other object Here are the possible scenarios that ReferenceError document is not defined error might happen A reference to the document object in Node jsServer side Rendering SSR Casing might be off Let s see how we can fix them How to fix document is not defined errorIn Node js As mentioned earlier the document object is a browser feature and not a part of JavaScript On the other hand when there s no browser there s no document object With Node js you must review the code and figure out why you re accessing a browser object in a server side code in the first place Maybe it s just there because you borrowed the code from another file However if your code is used by both the front end and the server you can place the reference to the document inside a conditional statement to ensure it ll only run by the browser s JavaScript engine To do this you can place it inside a conditional statement and check for the availability of the document object This code only runs on the browserif typeof document undefined let element document querySelector class name Manipulating the DOM here Serverside rendering SSR The document is not defined error might also occur when using static site generators such as Nuxt js Next js or Gatsby A quick fix as suggested above is to place any reference to the document object inside a conditional statement to exclude it from the server side rendering If you use Next js you can place your DOM related code inside a useEffect hook The callback passed to useEffect runs after the component is mounted and painted The example below is from React s documentation useeffect exampleimport React useState useEffect from react function Example const count setCount useState Similar to componentDidMount and componentDidUpdate useEffect gt Update the document title using the browser API document title You clicked count times return lt div gt lt p gt You clicked count times lt p gt lt button onClick gt setCount count gt Click me lt button gt lt div gt How about Nuxt js If you re using Nuxt js with Vue and the error is raised in one of your components you can wrap your component inside a lt client only gt component and the error will go away lt client only gt guarantees that your component is only rendered on the client side nuxtjs client only js lt template gt lt div gt lt client only placeholder loading gt lt your component gt lt client only gt lt div gt lt template gt Additionally you can access DOM from within the mounted Vue lifecycle hook Or maybe it s just a typo It s also worth checking the document object is all lowercase and not capitalized document reference case js WrongDocument querySelector class name Correctdocument querySelector class name Wrapping upIn this quick guide you learned the document object is a browser feature and should always be used in a browser environment The most common reason for this error is that the code tries to access the document object in a non browser environment such as Node js Two common way to avoid such errors is to use a conditional statement to ensure the code only runs in the browser Alternatively you can use hook mechanisms in case you re using an SSR framework such as Next or Nuxt js I hope this guide
