Twitter binding spec

Setup Dapr component

The Twitter binding supports both input and output binding configuration. First the common part:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: bindings.twitter
  version: v1
  metadata:
  - name: consumerKey
    value: "****" # twitter api consumer key, required
  - name: consumerSecret
    value: "****" # twitter api consumer secret, required
  - name: accessToken
    value: "****" # twitter api access token, required
  - name: accessSecret
    value: "****" # twitter api access secret, required

Input bindings

For input bindings, where the query matching Tweets are streamed to the user service, the above component has to also include a query:

  - name: query
    value: "dapr" # your search query, required 

Output bindings

For output binding invocation the user code has to invoke the binding:

POST http://localhost:3500/v1.0/bindings/twitter

Where the payload is:

{
  "data": "",
  "metadata": {
    "query": "twitter-query",
    "lang": "optional-language-code",
    "result": "valid-result-type"
  },
  "operation": "get"
}

The metadata parameters are:

• query - any valid Twitter query (e.g. dapr or dapr AND serverless). See Twitter docs for more details on advanced query formats
• lang - (optional, default: en) restricts result tweets to the given language using ISO 639-1 language code
• result - (optional, default: recent) specifies tweet query result type. Valid values include:
  • mixed - both popular and real time results
  • recent - most recent results
  • popular - most popular results
