The v0.18 release includes improvements to API key handling and workflows when using continuous integration.
When authenticating with
mix hex.user auth we now generate two API keys instead of single one. One key is unencrypted with read access and the other is encrypted with your local password and has full read/write access to the API. Hex encrypts the API key for security reasons, for example you cannot run
mix hex.publish without providing a password, but it meant that commands such
mix hex.search required password which felt unnecessary. Now commands that don’t make any changes will not require a password.
Additionally, we generate a single key that gives access to all your organization repositories, instead of one key for each repository. It also has the added benefit that you don’t have to reauthenticate if you are added to a new organization.
We have also added support for keys owned directly by an organization instead of a specific user, these keys can be accessed through
mix hex.organization and through the organization dashboard. This is useful when generating keys for a CI environment, previously when personal keys were used, a person leaving an organization or revoking the key could negatively affect CI workflow.
HEX_API_KEY environment variable has been introduced to be able run commands that require an authentication without having to authenticate manually with
mix hex.user auth which has user input prompts. The key set with
HEX_API_KEY can be generated with
mix hex.user key generate or
mix hex.organization key ORGANIZATION generate. It also makes it possible to run commands such as
mix hex.publish without being prompted for a password.
By passing the
--yes flag to
mix hex.publish you can publish your package (together with
HEX_API_KEY) without any confirmation prompts. This allows you to publish your package as part of your CI build process. Keep in mind that this will publish the package even if there are warnings from Hex and that you cannot inspect the compiled package contents before publishing so you should use this option with care.
This release focused on workflow improvements when working in CI environments and running commands that requires authentication. Users that have private packages will have better security because they can use specialized keys for their organizations.
The work of moving functionality from the Hex client to hex_erl is ongoing. hex_erl is an effort started by Hex team member Wojtek Mach, the idea is to move the core functionality needed to create a Hex package manager client to a common Erlang library. This reduces duplicate development effort and will allow tools such as rebar3 and erlang.mk to stay up to date with the latest changes and improvements to Hex.
Next up for the core team is releasing private HexDocs and adding annual billing for organizations. The full list of changes for Hex v0.18.0 is available in our release notes.
