Then install JS dependencies:\n\n```sh\nnpm install\n```\n\nTo run the tests:\n\n```sh\n# test compat Go -\u003e JS\nnode compat test go js\n\n# test compat JS -\u003e Go\nnode compat test js go\n```\n\n## Adding an implementation\n\nTo test an implementation it first needs a simple CLI to be implemented. All output must be `dag-json` encoded to allow the runner to easily inspect results.\n\nCreate a directory in the root and add a config file specifying the command to run to invoke the CLI. e.g. for a JS language implementation the config may look like:\n\n**`js/runner.config.json`**:\n\n```json\n{\n  \"command\": \"node cli.js\"\n}\n```\n\n### CLI API\n\nThe CLI must implement the following commands:\n\n#### `server start`\n\nStart a Ucanto server. The service URL and public identifier must be output.\n\nOutput:\n\n```json\n{\n  \"url\": \"http://127.0.0.1:9000\",\n  \"id\": \"did:key:z6MkjjaEwghJ9C2Y2wv1MFAuRL25UFLqCHwjh5aE2L9nxqjZ\"\n}\n```\n\nNote: the server process must continue to run after logging the output and terminate on SIGTERM.\n\n#### `key gen`\n\nGenerate a private key.\n\nOptional parameters:\n\n* `--type` - type of key to generate (\"ed25519\" or \"rsa\"). Default: \"ed25519\"\n\nOutput:\n\n```json\n{\n  \"id\": \"did:key:z6MkrPpjGnP9KuPptDvqw8ueB8rGNh8wEPoKxjF2MjRJiGxH\",\n  \"key\": { \"/\": { \"bytes\": \"gCaSb6WUYb/g6fycZa22xD0Q2JueTLPWxCtG3LNA3FZkhu0BsWrgQI4ZkTAcc7OqA1AYogtyCbN83PtmNPqkrwYirJo\" } }\n}\n```\n\n#### `delegation create --issuer --audience --resource --ability`\n\nCreate a delegation. Required parameters:\n\n* `--issuer` - base64 encoded _private_ key of the issuer\n* `--audience` - DID of the intended receipient\n* `--resource` - DID of the resource the delegation applies to\n* `--ability` - name of the capability to delegate (may be specified multiple times)\n\nOptional parameters:\n\n* `--expiration` - expiration in seconds from unix epoch (if not supplied the delegation MUST not expire)\n* `--proof` - base64 encoded archive of delegations to include as proofs\n\nOutput:\n\n```json\n{\n  \"delegation\": { \"/\": { \"bytes\": \"...\" } }\n}\n```\n\n#### `invoke --url --issuer --audience --resource --ability --caveats`\n\nIssue an invocation. Required parameters:\n\n* `--url` - service URL\n* `--issuer` - base64 encoded _private_ key of the issuer\n* `--audience` - DID of the intended receipient (typically the service DID)\n* `--resource` - DID of the resource the invocation applies to\n* `--ability` - name of the capability to delegate (may be specified multiple times)\n\nOptional parameters:\n\n* `--caveats` - dag-json encoded parameters for the invocation\n* `--proof` - base64 encoded archive of delegations to include as proofs\n\nOutput:\n\n```json\n{\n  \"headers\": {\n    \"Content-Type\": \"application/vnd.ipld.car\",\n    \"...\": \"...\"\n  },\n  \"body\": { \"/\": { \"bytes\":\"OqJlcm9vdHOB2CpYJQABcRIgqwMj1r...\" } }\n}\n```\n\n### Server implementation\n\nThe server MUST operate a Ucanto service at `/` and MUST shut itself down shortly after receiving a request to `POST /shutdown` (and respond with a `202 Accepted` status).\n\nThe server should accept and execute invocation provided the delegation chain is valid. i.e. the issuer does not need explicit delegation from the server to invoke - invocation are acceptable provided the issuer _is_ the resource (self signed) or the issuer is provably delegated to by a self signed delegation.\n\nThe following invocation handlers MUST be implemented:\n\n#### `test/echo`\n\nInput:\n\n```json\n{ \"echo\": \"...\" }\n```\n\nResult:\n\n```json\n{ \"ok\": { \"echo\": \"...\" } }\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstoracha%2Fucanto-compat","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstoracha%2Fucanto-compat","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstoracha%2Fucanto-compat/lists"}
