The reason it might work in UI mode but not headless is that sites who aggressively fight scraping will detect that you are running in a headless browser. Some possible workarounds: Use puppeteer-extra Found here: https://github.com/berstend/puppeteer-extra Check out their docs for how to use it. It has a couple plugins that might help in getting … Read more
In the app directory, by default, Next.js uses Server Components, where the JSX gets compiled to “pure HTML” and sent to the browser. Like any traditional Backend with a templating engine, such as Express with EJS, and Laravel with Blade. This is for better performance, as you can read on the doc: Server Components allow … Read more
[id^=’someId’] will match all ids starting with someId. [id$=’someId’] will match all ids ending with someId. [id*=’someId’] will match all ids containing someId. If you’re looking for the name attribute just substitute id with name. If you’re talking about the tag name of the element I don’t believe there is a way using querySelector
Promise.all accepts an Array of Promise objects. You’re getting an Array of undefined because you’re not returning any Promise in your map callback: function addText(queries) { return Promise.all(queries.map(function(query) { // Add `return` here or the `map` returns an Array of `undefined`. return models.queries .findById(query.queryId, { raw: true, attributes: [ “query” ] }) .then(function(queryFetched) { query.text … Read more
A programmer will use flush() when they want to ensure that the previous code’s output and/or effects are written to the spreadsheet before continuing. If you do not flush(), then the code may be automatically “optimized” by using some built-in caching and bundling of operations. In general, you do not need to use flush() until … Read more
for in loops over enumerable property names of an object. for of (new in ES6) does use an object-specific iterator and loops over the values generated by that. In your example, the array iterator does yield all the values in the array (ignoring non-index properties).
If you’re running in a browser, then the easiest way is just to let the browser do it for you… function stripHtml(html) { let tmp = document.createElement(“DIV”); tmp.innerHTML = html; return tmp.textContent || tmp.innerText || “”; } Note: as folks have noted in the comments, this is best avoided if you don’t control the source … Read more
This is because require() does not exist in the browser/client-side JavaScript. Now you’re going to have to make some choices about your client-side JavaScript script management. You have three options: Use the <script> tag. Use a CommonJS implementation. It has synchronous dependencies like Node.js Use an asynchronous module definition (AMD) implementation. CommonJS client side-implementations include … Read more
Firefox interprets function statements differently and apparently they broke declaration hoisting for the function declaration. ( A good read about named functions / declaration vs expression ) Why does Firefox interpret statements differently is because of the following code: if ( true ) { function test(){alert(“YAY”);} } else { function test(){alert(“FAIL”);} } test(); // should … Read more
