Samply.Spot

This is the Rust re-implementation of Samply.Spot.

Local setup

Spot can be run locally with the provided docker-compose which requires a running beam installation. This can be done by cloning the beam repository and running ./dev/beamdev demo

Spot can also be run from command line stating command line parameters, like so:

cargo run -- --beam-proxy-url http://localhost:8081 --beam-app-id app1.proxy1.broker --beam-secret App1Secret --cors-origin any --bind-addr 127.0.0.1:8055 --catalogue-url https://raw.githubusercontent.com/samply/lens/main/packages/demo/public/catalogues/catalogue-dktk.json

The following environment variables are mandatory for the usage of Spot.

--beam-proxy-url <BEAM_PROXY_URL>
    URL of the Beam Proxy, e.g. https://proxy1.broker.samply.de [env: BEAM_PROXY_URL=]
--beam-app-id <BEAM_APP_ID>
    Beam AppId of this application, e.g. spot.proxy1.broker.samply.de [env: BEAM_APP_ID=]
--beam-secret <BEAM_SECRET>
    Credentials to use on the Beam Proxy [env: BEAM_SECRET=]
--cors-origin <CORS_ORIGIN>
   Where to allow cross-origin resourse sharing from [env: CORS_ORIGIN=]

Optional environment variables:

--project <PROJECT>
    Optional project name used by focus [env: PROJECT=]
--catalogue-url <CATALOGUE_URL>
    URL to catalogue.json file, if not stated, /catalogue endpoint is disabled [env: CATALOGUE_URL=]
--prism-url <PRISM_URL>
    URL to prism, if catalogue-url is not stated, this is never used [env: PRISM_URL=] [default: http://localhost:8066]
--bind-addr <BIND_ADDR>
    The socket address this server will bind to [env: BIND_ADDR=] [default: 0.0.0.0:8055]

API

/beam

The /beam endpoint provides the ability to communicate with the beam-broker through a locally hosted beam-proxy (See local setup).

POST

With a post to /beam you will create a new beam task. You need to send a payload with this structure:

{
    "id": "<a-uuid-to-later-identify-the-task>",
    "sites": [
        "list",
        "of",
        "available",
        "sites"
    ],
    "query": "The query which the receiving site should execute"
}

See the example call in our docs.

Success

When executing the query successfully, spot will return a 201 status code with the beam task id in the location header

HTTP/1.1 201 Created
Location: /beam/<some-uuid>
Content-Length: 0
Date: Mon, 15 Mai 2023 13:00:00 GMT

GET

The get endpoint takes a beam task id in the path.

curl http://localhost:8100/beam/<some-uuid>

See the example call

/catalogue

GET

curl http://localhost:8100/catalogue

Returns JSON catalogue of search criteria along with metadata fetched from Samply.Prism (see Prism's repository for a list of metadata fields).
