We’re about to find out if the progress on both speed and battery life promised at the November 10th presentation will b

APIs. I use Express.JS to quickly build access points when needed. Those access points are designed to be very light. I prefer to extract the information I need from the request and then call a solution specific logic layer to do any data processing or retrieval. That logic layer in turn calls out to data objects which interact with the database to store/retrieve data from persistent storage. I’ll create REST end points where it makes sense, but I’ll also create POST endpoints for the more complex requests.

Improvement from comment: The shorthand technique (JSON.parse(JSON.stringify(obj))) doesn’t work if your object property contains function, undefined or NaN as value. Because when you JSON.stringify the object, the property containing function, undefined or NaN as value gets removed from the object.

Websockets. When it makes sense I’ll use the ws module to create a socket server. I may set up express-ws as well to create an HTTP/HTTPS endpoint to access the socket server. When possible I try to use the same business logic objects the API calls.

Scheduled Tasks. I create JS files that perform a specific task. This could be purging outdated logs, processing the job queue, doing bulk emails out of band, etc. I write each script with a single intent, and then use CRON to call that script at a reasonable interval. These tasks are usually the more processing intensive things that would not play well within a web page. Or are house keeping chores to keep the application humming along at a brisk pace.

I use Node to develop solutions for my customers. Those solutions may just be an API, or integrating with a front end framework over a REST interface. But those solutions sometimes involve setting up WebSocket servers, command line scripts, one-off data manipulation tasks, creating or accessing job queues, or even a comprehensive package that does everything in a modular way.

e moment my son received vaccinations as an infant. He held onto me and my eyes welled up with tears as my husband innocently chuckled as he watched my reaction. All I could see was the fear in my baby boy’s eyes as he braced himself for the unknown. It didn’t matter that I knew the vaccine was protecting him. In that moment, I was living vicariously through my adorable little man and I felt his pain.

To deep clone a multi-level object, we can iterate through each property and check if the current property contains an object. If yes, then do a recursive call to the same function by passing the current property value (i.e. the nested object).

Now, let’s go back to Federighi’s Independent interview where he claims that Apple “[wasn’t] remotely considering something about touch” and compare that to the Magic Keyboard intro where Apple “deeply considered the best way to bring a cursor to a Touch environment.”

Improvement from comment: The shorthand technique (JSON.parse(JSON.stringify(obj))) doesn’t work if your object property contains function, undefined or NaN as value. Because when you JSON.stringify the object, the property containing function, undefined or NaN as value gets removed from the object.

Data Access. I use Knex.js for creating my data models when I am dealing with relational databases. For non-relational databases I’ll use the appropriate library. Either way I wrap the access to the data store into meaningful data objects that can be used independently from the application. This allows me to call my data items from batch files, or other applications with little effort.

File Management. There are times we just need to move a file, or remove it, or read the contents. I use the nativefs module, or the fs-extra module to perform these steps. I use through2 when I’m using streams to process large data sets and need to pipe structured data into another step. I’ll also use fast-csv to work with CSV files.

Pre — Deployment processing. In practice this is normally running Webpack, Parcel, or another bundler system against the code. Sometimes though there is preparation work to be done when the next set of code is deployed — applying database structure changes, revising any dynamic templates, collecting files, etc. In these cases I write a script that does any other steps that the bundler system can’t handle. In essence it is batch processing.

Business Logic. I like to isolate the application logic into a separate layer, especially for the non-trivial applications. It is handy to separate what we want to do from how we ask for it to happen, and how the data is stored. I find that this separation gives me greater flexibility to respond to the evolving needs of the application without getting bogged down in the communication methods. It also makes breaking the application into smaller modules much easier.

To loop through an array we normally use the traditional for loop. We can make use of the for...of loop to iterate through arrays. To access the index of each value we can use for...in loop.

Batch Processing. Too often I have created an interface to allow for easy data capture. Then management wants to do a bulk entry, but do not want expose a bulk entry process in the application interface. This could be pre-populating the application with years of data, or ALL the products, or updating 100s or user records at once. These tasks may be one-off things, or could be recurring on a regular basis. Either way the work to be done is pretty much the same. Read the source data, massage it in some way, then do something with that data.
