cpp-search-engine

10 best C++ Search Engine

The use of a library for searching is important in C++ because it allows you to get all the functionality needed for searching from a single location, instead of having to write everything yourself. It helps avoid code duplication and makes your program easier to maintain. C++ Search Engine libraries like typesense, annoy, nanoflann are great for providing fast and easy-to-use search functionality. Typesense is a library for building search engines in C++. It uses the same algorithm as Lucene (the Java library used in Elasticsearch) and has very similar APIs. The biggest difference between Typesense and Lucene is that Typesense uses compile-time reflection to generate code for each indexing operation and uses template metaprogramming to generate code for the query engine. Nanoflann is a C++ template library with bindings in other languages such as C#, Java and Python. The library provides support for approximate nearest neighbors queries on multi-dimensional data sets stored in binary formats such as BLASTER XML or HDF5 with multithreaded computation.

QUESTION

Javascript dynamically inserted later on: how to make it run?

Asked 2022-Apr-17 at 14:12

I have scripts In my React app that are inserted dynamically later on. The scripts don't load.

In my database there is a field called content, which contains data that includes html and javascript. There are many records and each record can include multiple scripts in the content field. So it's not really an option to statically specify each of the script-urls in my React app. The field for a record could for example look like:

1<p>Some text and html</p>
2<div id="xxx_hype_container">
3    <script type="text/javascript" charset="utf-8" src="https://example.com/uploads/hype_generated_script.js?499892"></script>
4</div>
5<div style="display: none;" aria-hidden="true"> 
6<div>Some text.</div> 
7Etc…
8

I call on this field in my React app using dangerouslySetInnerHTML:

1<p>Some text and html</p>
2<div id="xxx_hype_container">
3    <script type="text/javascript" charset="utf-8" src="https://example.com/uploads/hype_generated_script.js?499892"></script>
4</div>
5<div style="display: none;" aria-hidden="true"> 
6<div>Some text.</div> 
7Etc…
8render() {
9    return (
10        <div data-page="clarifies">
11            <div className="container">
12                <div dangerouslySetInnerHTML={{ __html: post.content }} />
13                ... some other data
14            </div>
15        </div>
16    );
17}
18

It correctly loads the data from the database and displays the html from that data. However, the Javascript does not get executed. I think the script doesn't work because it is dynamically inserted later on. How can I make these scripts work/run?

This post suggest a solution for dynamically inserted scripts, but I don't think I can apply this solution because in my case the script/code is inserted from a database (so how to then use nodeScriptReplace on the code...?). Any suggestions how I might make my scripts work?

Rendering raw HTML without React recommended method is not a good practice. React recommends method dangerouslySetInnerHTML to render raw HTML.
