Support for v8js extension

[izniburak]

Hi,

Firstly, thanks for this great repo! Could you please share information about the v8js extension? Does the repo has support for this extension? If not exists, could you please add it?

Thanks.

The list of supported extensions is listed at https://github.com/mlocati/docker-php-extension-installer#supported-php-extensions

I'll try to find some time to check if/how v8js can be added to the script.

I'd love to see this! 🙏

Debian has libnode-dev and Alpine has nodejs-dev for getting libv8.

I haven't switched over to your script yet so I use this currently:

FROM alpine:3.22 AS phpv8js-builder

# Install build dependencies
RUN apk add --no-cache \
    php83-dev \
    gcc \
    g++ \
    make \
    autoconf \
    automake \
    libtool \
    pcre-dev \
    bison \
    re2c \
    musl-dev \
    nodejs-dev

# Install php v8js
RUN set -eux; \
    cd /tmp; \
    curl -sSL -o ./v8js.tar.gz https://github.com/phpv8/v8js/archive/refs/heads/php8.tar.gz; \
    tar -xzf v8js.tar.gz; \
    cd v8js-php8; \
    phpize; \
    ./configure; \
    make; \
    make install; \
    rm -rf /tmp/*

FROM alpine:3.22 AS runtime
RUN apk add --no-cache nodejs-dev
COPY --from=phpv8js-builder /usr/lib/php83/modules/v8js.so /usr/lib/php83/modules/v8js.so
RUN echo "extension=v8js" > /etc/php83/conf.d/v8js.ini

Not sure if that's optimal, but it works. :)

Here is some basic test code:

<?php
$context = new \V8Js();
try {
    ob_start();
    $return = $context->executeString('
        function test() {
            return "Hello from V8!";
        }
        print(test());
        test();
    ');
    $output = ob_get_clean();
    echo "<p>V8 Output: " . htmlspecialchars($output) . "</p>";
    echo "<p>V8 Return Value: " . htmlspecialchars(print_r($return, true)) . "</p>";
} catch (V8JsException $e) {
    echo "V8JsException: " . $e->getMessage();
} catch (Exception $e) {
    echo "Exception: " . $e->getMessage();
}
