ember-cli-deploy-revision-key

An ember-cli-deploy plugin to generate a unique revision key based on the current build

---

**WARNING: This plugin is only compatible with ember-cli-deploy versions >= 0.5.0**

---

This plugin will generate a unique revision key for the current build. The revision key can be used to uniquely identify the particular version of the application.

What is an ember-cli-deploy plugin?

A plugin is an addon that can be executed as a part of the ember-cli-deploy pipeline. A plugin will implement one or more of the ember-cli-deploy's pipeline hooks.

For more information on what plugins are and how they work, please refer to the Plugin Documentation.

Configuration Options

For detailed information on how configuration of plugins works, please refer to the Plugin Documentation.

type

The type of Key Generator to be used.

Default: 'file-hash' Alternatives: 'git-tag-commit', 'version-commit'

Key Generators

Key generators are the strategies used to generate the unique revision key. Currently there is only one Key Generator implementation but we will add more as needed. Some examples of other potential key generators are GitHash or DateTime generators.

File Hash generator

This key generator will fingerprint the index.html and return an MD5 hash. The generation of the revision key, using this generator, is guaranteed to be idempotent. That is, the same revision key will be generated for the same set of project files. If the project files change in any way, this will be reflected by a change in the revision key.

Configuration Options

filePattern

A pattern that matches the file you would like to be fingerprinted. This pattern should be relative to distDir.

Default: index.html

distDir

The root directory where the file matching filePattern will be searched for. By default, this option will use the distDir property of the deployment context, provided by ember-cli-deploy-build.

Default: context.distDir

distFiles

The list of built project files. This option should be relative to distDir and should include the file that matches filePattern. By default, this option will use the distFiles property of the deployment context, provided by ember-cli-deploy-build.

Default: context.distFiles

Git Tag Commit generator

Creates a key based on the most recent git tag and the currently checked-out commit. The tag is the tag identifier, followed by a + symbol, followed by the first 8 characters of the commit hash.

For example, if your most recent git tag is v2.0.3, and the current commit is 0993043d49f9e0[...], this generator will return a revision of v2.0.3+0993043d.

Version Commit generator

Similar to the Git Tag Commit generator, but uses the package.json version string instead of the git tag. The JSON file containing the version string can be configured with the versionFile option.

Configuration Options

versionFile

The file containing your project's version number. Must be a JSON file with a top-level version key. Only used by the version-commit key generator.

Default: package.json

Prerequisites

The following properties are expected to be present on the deployment context object:

• distDir (provided by ember-cli-deploy-build)
• distFiles (provided by ember-cli-deploy-build)
