Compressing HTTP Messages with Gzip

English — 日本語に切り替える

Last updated January 27, 2022

Heroku does not modify HTTP requests or responses that are sent by your application. This means that features like HTTP compression are your application’s responsibility.

You can easily serve Gzipped HTTP messages directly from your application code. Here are documentation links for popular Gzip compression libraries for all Heroku-supported languages:

Language Libraries
Node.js compression (Express middleware), Zlib
Ruby Zlib
Python gzip (standard library), django.middleware.gzip
PHP gzencode
Java Spring, Tomcat, Jetty
Scala Play
Clojure Jetty
Go gzip
