For example, a commonly used header called "UserAgent" tells a website what type of device you are using so it can tailor the best experience for you. Finally, in line 10, we echo the downloaded content to the terminal. Consuming Node.js Microservices Created with Stdlib For example, let’s only return the forecast objects for days that it might rain: This jq syntax selects objects in the JSON array where the precipitation is forecasted to be greater than zero. To be able to read the result, we call the method toString to convert the result to a string that we can compare. We start with the settings area. Let’s start using jq and do a pretty print of the JSON returned: As you might guess, the results returned look very similar to our JSON results presented above in the API description above. We need the new class because we want to fill events with code. The jq . Support these free tutorials by buying something on Amazon with this link. Now we have a string that still has quotation marks, which we can replace with an empty string by using the ReplaceAll method. . To set the temperature unit we use a popup menu. Creating Node.js Microservices with Ease Using Stdlib The paths of the other information can be read and build similarly. We can use this. The answer is yes! So we need the text in our program.

Every request, either by browser or application, sends header information every time you visit any website. Thanks for asking this excellent question. The results, sorted in descending orde by low temperature, look like this: We can also return just the maximum value using jq’s max_by function. Developers can override these headers for specific purpos… We look whether there are also these keys with a normal and valid, functioning query. These can then also be decorated appropriately. Let’s sort by the low temperature: How about sorting in descending order? As a first step, log into your Linux system and launch a terminal session to verify that curl is installed (if you are running Raspbian, curl ships with the base image): We see that usr/bin/curl is returned so we know curl is installed.

This enables the script to return 67°F Sunny instead of "67°F Sunny". I had an issue with the Weather API used in the examples, and this issue has been resolved. (My instructions will, however, be geared toward Debian-based Linux distros since we will be using the apt command.) To set up a Raspberry Pi, you can follow the instructions in my popular Beginner’s Guide to Installing Node.js on a Raspberry Pi. You can check out a follow-up article I wrote called Using jq and curl to Wrangle JSON Arrays from the Terminal and also the jq Manual to learn about many of jq’s other features. JSON has become the lingua franca for exchanging data on the web, and we (as developers) need to know how to process JSON data so we can be positioned for the present and for the future.
