@cpp.js/package-curl

Precompiled CURL library built with cpp.js for seamless integration in JavaScript, WebAssembly and React Native projects.

Integration

Start by installing these package with the following command:

npm install @cpp.js/package-curl

To enable the library, modify the cppjs.config.js file as shown below.

+import curl from '@cpp.js/package-curl/cppjs.config.js';

export default {
    dependencies: [
+        curl
    ]
    paths: {
        config: import.meta.url,
    }
};

Usage

Below are the steps to use the curl in your C++ or JavaScript code.

Usage in C++ Code

+#include <curl/curl.h>

+size_t WriteCallback(void* contents, size_t size, size_t nmemb, std::string* output) {
+    size_t totalSize = size * nmemb;
+    output->append((char*)contents, totalSize);
+    return totalSize;
+}

std::string Native::sample() {
+    std::string result = "";
+    std::string response;
+    char errbuf[CURL_ERROR_SIZE*100];
+
+    CURL* curl = curl_easy_init(); // Initialize libcurl
+    curl_easy_setopt(curl, CURLOPT_CAINFO, getenv("CURL_CA_BUNDLE"));
+    curl_easy_setopt(curl, CURLOPT_URL, "https://test22.free.beeceptor.com"); // Set the URL
+    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "{\"a\": 2}");
+    struct curl_slist *headers = NULL;
+    headers = curl_slist_append(headers, "Content-Type: application/json");
+    headers = curl_slist_append(headers, "Accept: application/json");
+
+    curl_easy_setopt(curl, CURLOPT_ERRORBUFFER, errbuf);
+    errbuf[0] = 0;
+    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback); // Set callback to handle data
+    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response); // Pass the response string
+    CURLcode res = curl_easy_perform(curl);
+    if (res == CURLE_OK) {
+        result = "response: " + response;
+    } else {
+        std::string errorStr = errbuf[0] ? std::string(errbuf) : curl_easy_strerror(res);
+        result = "curl error: " + errorStr;
+    }
+
+    curl_slist_free_all(headers);
+    curl_easy_cleanup(curl);
+
+    return result;
}
