    Hello,

    I'm glad to announce a new release of NGINX JavaScript module (njs).

    This release focuses on extending the modules functionality.

    Notable new features:
    - js_body_filter directive. The directive allows changing the
    response body.
    : nginx.conf:
    : js_import foo.js;
    :
    : location / {
    : js_body_filter foo.to_lower;
    : proxy_pass http://127.0.0.1:8081/;
    : }
    :
    : foo.js:
    : function to_lower(r, data, flags) {
    : r.sendBuffer(data.toLowerCase(), flags);
    : }
    :
    : export default {to_lower};
    - njs.on('exit') callback. The "exit" hook allows to implement
    some cleanup logic before the VM instance is destroyed.
    : foo.js:
    : function handler(r) {
    : njs.on('exit', () => {
    : r.warn("DONE");
    : });
    : }
