Action Destinations are a way to build streaming destinations on Segment. To begin, follow the instructions in Get Started below.
Fore more detailed instruction, see the following READMEs:
This is a monorepo with multiple packages leveraging lerna with Yarn Workspaces:
packages/ajv-human-errors- a wrapper around AJV errors to produce more friendly validation messagespackages/browser-destinations- destination definitions that run on device via Analytics 2.0packages/cli- a set of command line tools for interacting with the repopackages/core- the core runtime engine for actions, including mapping-kit transformspackages/destinations-actions- destination definitions and their actionspackages/destinations-subscriptions- validates events against an action's subscription AST
You'll need to have some tools installed locally to build and test action destinations.
- Yarn 1.x
- Node 14.17 (latest LTS, we recommand using
nvmfor managing Node versions)
If you are a Segment employee you can directly git clone the repository locally. Otherwise you'll want to fork this repository for your organization to submit Pull Requests against the main Segment repository. Once you've got a fork, you can git clone that locally.
# Clone the repo locally
git clone <your fork or https://github.com/segmentio/action-destinations.git>
cd action-destinations
npm login
yarn login
# Requires node 14.17, optionally: nvm use 14.17
yarn --ignore-optional
yarn bootstrap
# Run unit tests to ensure things are working! All tests should pass :)
yarn testIn order to run the CLI (./bin/run), your current working directory needs to be the root of the action-destinations repository.
# see what's supported by the CLI
./bin/run --help
# scaffold a new destination
./bin/run init
# scaffold a new action within a destination
./bin/run generate:action <ACTION_NAME> <browser|server>
# generates TypeScript definitions for an integration
./bin/run generate:types
# start local development server
./bin/run serveFor specific information about each CLI command, please refer to this README.
If a CLI command fails to work properly, run the command with DEBUG=* at the beginning (e.g. DEBUG=* ./bin/run serve). This will produce a verbose debugging output, providing hints as to why something isn't working as expected. All of the CLI commands are also in the ./packages/cli/src/commands directory if you need to inspect them further.
Refer here for more information about testing your destination actions.
Pass the Node flag --inspect when you run the local server, and then you can attach a debugger from your IDE. The serve command will pass any extra args/flags to the underlying Node process.
Action destinations are configured using a single Destination setting (subscriptions) that should contain a JSON blob of all subscriptions for the destination. The format should look like this:
[
{
"subscribe": "<fql query>",
"partnerAction": "<actionSlug>",
// See ./packages/core/src/mapping-kit/README.md for documentation. The keys in this object should match the `action.fields`
"mapping": { ... }
}
]Here's a full example:
[
{
"subscribe": "type = 'track'",
"partnerAction": "postToChannel",
"mapping": {
"text": {
"@template": "Tracked! event={{event}}, {{properties.text}}"
},
"url": "https://hooks.slack.com/services/0HL7TC62R/0T276CRHL/8WvI6gEiE9ZqD47kWqYbfIhZ",
"channel": "test-channel"
}
},
{
"subscribe": "type = 'identify'",
"partnerAction": "postToChannel",
"mapping": {
"text": {
"@template": "User identified! email={{email}}"
},
"url": "https://hooks.slack.com/services/0HL7TC62R/0T276CRHL/8WvI6gEiE9ZqD47kWqYbfIhZ",
"channel": "test-channel"
}
}
