As a web developer, you’re probably acutely aware of Node.js and WordPress. Node.js is an impressive runtime setting that runs JavaScript outdoor the browser, and WordPress is the principle content material control machine (CMS).
The ones platforms would possibly seem worlds apart — Node.js, with its JavaScript backbone, and WordPress, a PHP-powered CMS. However, they can artwork in tandem, on account of WordPress REST API. This API lets in Node.js methods to have interaction with WordPress by the use of HTTP requests. It provides get admission to to various knowledge, along side shoppers, comments, pages, posts, and other internet website elements.

Believe you could have a WordPress internet website and want to assemble a custom designed dashboard. This dashboard would possibly simply display real-time knowledge from your internet website, like recent posts, statement counts, and shopper process.
Proper right here’s where Node.js plays a pivotal serve as. This knowledge walks you by the use of setting up Node.js endpoints. The ones endpoints leverage the WordPress REST API for various tasks: updating posts, moderating comments, internet website customization, and tailored WordPress internet website control.
Should haves
To watch along with this data, we expect you could have:
- Basic knowledge of Node.js.
- Node.js and npm installed on your pc.
- WordPress and the Thunder Consumer VS Code extension installed.
Arrange WordPress Posts With Node.js
In WordPress, the foundational tasks include creating, updating, and deleting posts. This segment explains learn how to create particular endpoints for the ones actions, along with learn how to make requests to the /posts endpoint for every operation.
Creating a New Post in WordPress
To create a brand spanking new submit in WordPress with the REST API, make a POST request to the /posts endpoint. Throughout the body of the request, you need to provide the content material subject material of your WordPress submit in JSON construction.
First, open your Node.js server file, maximum ceaselessly named App.js. Ensure that Specific is correctly organize on your server file. This is maximum ceaselessly carried out with the street const app = particular(), which initializes Particular.
Next, put in force a trail on your server file with the intention to upload a brand spanking new submit. The code for this trail seems like this:
app.submit("/add-post", async (req, res) => {
check out {
const postID = req.body.id
const resp = look forward to axios.submit(`https://yourdomain.com/wp-json/wp/v2/posts/${postID}`, req.body)
if(resp.status !== 200) throw "Something went improper"
} catch (err) {
console.log(err)
}
})This code creates an endpoint /add-post on your application. When a request is shipped to this endpoint, it extracts the submit ID from the request body and sends a POST request to your WordPress internet website. Take into account to replace https://yourdomain.com at the side of your WordPress space.
You’ll test this using apparatus like Thunder Shopper in Visual Studio Code. Make sure that the JSON body of your request is authentic to steer clear of errors.
This way shall we in for surroundings pleasant and automated posting to your WordPress internet website from your application.
Updating an Present Post in WordPress
To exchange a submit with the WordPress API, make a PUT request to the /posts endpoint on your WordPress API. You moreover need to provide the up-to-the-minute content material subject material of your WordPress submit in JSON construction.
The trail for updating an provide submit in WordPress is as follows:
app.put("/update-post", async (req, res) => {

if(resp.status !== 200) throw "Something went improper"

console.log(err)
}
})For example, you’ll change a submit with an ID of 3 in WordPress with the following request in Thunder Shopper:
Deleting a Post in WordPress
To delete a submit in WordPress, make a DELETE request to the /posts endpoint using the unique ID of the submit you wish to have to delete.
app.delete("/delete-post", async (req, res) => {
check out {

const resp = look forward to axios.delete(`https://yourdomain.com/wp-json/wp/v2/posts/${postID}`)
if(resp.status !== 200) throw "Something went improper"
} catch (err) {
console.log(err)
}
})The result should appear to be this:
Moderating WordPress Comments With Node.js
The Feedback API means that you can get admission to and manipulate comments on your WordPress internet website from an application. Inside that API is an endpoint for creating, file, finding out, updating, and deleting comments on a WordPress internet website.
Let’s suppose you don’t want your WordPress internet website to put up comments with the phrase “Observe me.” In this example, you’ll use a regex expression to check every statement for that phrase previous to posting it.

check out {
let regex = /apply me/i;
let statement = req.body.statement
if(regex.test(statement)) throw "Oops! Contains the forbidden word"
const resp = look forward to axios.submit(`https://yourdomain/wp-json/wp/v2/comments`, req.body)
if(resp.status !== 200) throw "Something went improper"
} catch (err) {
console.log(err)
}
})With this trail, most simple comments that don’t include the phrase “Observe me” get printed on the website, while comments like the one underneath don’t get posted:

app.submit("/sign-up", async (req, res) => {
// Sign up for shopper
res.cookie("cookie_id", 123456)
res.cookie("lang", req.body.language)
res.status(200).json("Logged in.")
})Upon signing up, you get the shopper’s hottest language and send it to the browser as cookies along with the cookie_id.
Now, with the language stored throughout the browser, you’ll use it to fetch WordPress posts throughout the shopper’s language. This calls so that you can translate your posts in WordPress first.

app.get("/get-posts", async (req, res) => {
check out {
const lang = req.cookies.lang
const resp = look forward to axios.get(`https://mydomain.com/${lang}/wp-json/wp/v1/posts`)
if(resp.status !== 200) throw "Something went improper"

console.log(err)
}

if(resp.status !== 200) throw "Something went improper"
} catch (err) {
console.log(err)
}
})Throughout the request, go an object containing the ID of the shopper whose report you wish to have to switch, along with the new details.
