The manifest.json file must state the version of this component implementation, and the files must be bitwise identical to the contents of any update CRX with that version for that platform, as the system will attempt to apply differential updates over these files. If you are using ComponentInstaller, you simply need to make sure that your component implementation (and a corresponding manifest.json file) are written to DIR_COMPONENTS as part of the build. If you need the guarantee that some implementation of your component is always available, you must bundle a component implementation with the browser itself. Bundle with the Chrome Installer (Optional) This is done in RegisterComponentsForUpdate. file_type_policies_component_ is a good example to work from.Ĭomponents need to be registered with the component updater. You must provide a ComponentInstallerPolicy object to a new ComponentInstaller. New components should use component_installer if possible, as this provides you with transparent differential updates, version management, and more. You will need the SHA256 hash of the public key generated in the previous step, as well as the CRX ID, which consists of the first half (128 bits) of that hash, rendered as hexadecimal using the characters a-p (rather than 0-9a-f). Installers live at src/chrome/browser/component_updater.

The “installer” is a piece of Chrome code that the component updater will run to install or update the component. If you plan to release the component using Google infrastructure, this file can be generated for you automatically. If nothing else, the manifest file must specify the component's version and name. You will additionally need to create a manifest.json file. Otherwise, you can create an RSA key pair using openssl or a similar tool. If you are a Googler, follow the instructions at for maximum key security.

Create a CRX Package Signing Key & Manifest (Non-Google)Īll components are delivered as CRX files (signed ZIP archives). This assumes you've already done the hard work of splitting your functionality out into a dynamically-linked library or data file. Additional work is necessary to integrate with the Omaha servers, and is covered in Google-internal documentation. This document covers the work that must be done on the client side.

A crx file is any file in the CRX package format.

A component is any element of Chrome's core functionality that is sometimes delivered by the component updater separately from the browser itself, usually as a dynamically-linked library or data file.

In the normal configuration, the component updater registers all components during (or close to) browser start-up, and then begins checking for updates six minutes later, with substantial pauses between successive update application. The primary drawback is that they require Chrome to tolerate their absence in a sane way. The primary benefit of components is that they can be updated without an update to Chrome itself, which allows them to have faster (or desynchronized) release cadences, lower bandwidth consumption, and avoids bloat in the (already sizable) Chrome installer.

It runs in the browser process and communicates with a set of servers using the Omaha protocol to find the latest versions of components, download them, and register them with the rest of Chrome.

The Component Updater is a piece of Chrome responsible for updating other pieces of Chrome.
