# Our Release Process
## Notes
BigchainDB follows
[the Python form of Semantic Versioning](https://packaging.python.org/tutorials/distributing-packages/#choosing-a-versioning-scheme)
(i.e. MAJOR.MINOR.PATCH),
which is almost identical
to [regular semantic versioning](http://semver.org/), but there's no hyphen, e.g.
-`0.9.0` for a typical final release
-`4.5.2a1` not `4.5.2-a1` for the first Alpha release
-`3.4.5rc2` not `3.4.5-rc2` for Release Candidate 2
**Note:** For Git tags (which are used to identify releases on GitHub), we append a `v` in front.
We follow [BEP-1](https://github.com/bigchaindb/BEPs/tree/master/1), which is our variant of C4, the Collective Code Construction Contract, so a release is just a [tagged commit](https://git-scm.com/book/en/v2/Git-Basics-Tagging) on the `master` branch, i.e. a label for a particular Git commit.
## Steps
1. Make sure you have a recent version of node and npm.
1.`npm install`
1. Update all npm package dependencies, where possible. You might have to freeze some versions. Run all tests locally (`npm run test`) and make sure they pass. Make a pull request (to be merged into the `master` branch) and make sure all tests are passing there (in Travis). Merge the pull request.
1. Make sure your local `master` branch is in sync with GitHub: `git checkout master` and `git pull`
1. Do a test build:
`npm run build`
If that fails, then get it working.
1. We use the [release-it](https://www.npmjs.com/package/release-it) package (from npm) to automate most of the release. Make sure you have a recent version.
1. Login to npm using your npm credentials, so you can publish a new [bigchaindb-driver](https://www.npmjs.com/package/bigchaindb-driver) package there. (The npm account must have permission to do so).
and then make that token available as an environment variable, e.g.
`export GITHUB_TOKEN="f941e0..."`
1. Do the release:
- For a patch release, do `npm run release`
- For a minor release, do `npm run release-minor`
- For a major release, do `npm run release-major`
If your npm account is using two-factor authentication,
you will have to append a one-time password (OTP) like `--npm.otp=123456`.
The above command will automatically do a bunch of things:
- bump the project version in `package.json`, then git commit and git push it.
- create a new Git tag of the form `v{verson}`, e.g. `v1.2.3`
- create a new [GitHub release](https://github.com/bigchaindb/js-bigchaindb-driver/releases).
- publish a new npm release
To see all the arguments passed to `release-it`, search for "release" in [package.json](package.json). The arguments are documented in the [release-it GitHub repo](https://github.com/release-it/release-it).
1. Make sure everything worked as expected.
- Was the version number bumped properly in [package.json](package.json)?
- Was a new Git tag created? See the [list of tags](https://github.com/bigchaindb/js-bigchaindb-driver/tags).
- Was a new GitHub release created? See the [list of releases](https://github.com/bigchaindb/js-bigchaindb-driver/releases).
- Was a new npm package published on npm? [Check on npmjs.com](https://www.npmjs.com/package/bigchaindb-driver).
1. You can edit the description of the GitHub release to add or remove details.
If the docs were updated since the last release, [login to readthedocs.org](https://readthedocs.org/accounts/login/) and go to the **BigchainDB JavaScript Driver** project, then:
1. Click on "Builds", select "latest" from the drop-down menu, then click the "Build Version:" button.
1. Wait for the build of "latest" to finish. This can take a few minutes.
1. Go to Admin --> Advanced Settings
and make sure that "Default branch:" (i.e. what "latest" points to)
is set to the new release's tag, e.g. `v0.9.1`.
(It won't be an option if you didn't wait for the build of "latest" to finish.)
Then scroll to the bottom and click "Save".
1. Go to Admin --> Versions
and under **Choose Active Versions**, do these things:
1. Make sure that the new version's tag is "Active" and "Public"
1. Make sure the **stable** branch is _not_ active.
1. Scroll to the bottom of the page and click "Save".
Congratulations, you have released a new version of the BigchainDB JavaScript Driver!
