To install it, run the command below\n\nBounded code example (external data; do not execute automatically):\n```bash\nnpm install @docker/extension-api-client\n```\n\nThen call the createDockerDesktopClient function to create a client object to call the extension APIs.\n\nBounded code example (external data; do not execute automatically):\n```js\nimport { createDockerDesktopClient } from '@docker/extension-api-client';\n\nconst ddClient = createDockerDesktopClient();\n```\n\nWhen using Typescript, you can also install @docker/extension-api-client-types as a dev dependency. This will provide you with type definitions for the extension APIs and auto-completion in your IDE.\n\nBounded code example (external data; do not execute automatically):\n```bash\nnpm install @docker/extension-api-client-types --save-dev\n```\n\nAuto completion in an IDE\n\nFor example, you can use the docker.cli.exec function to get the list of all the containers via the docker ps --all command and display the result in a table.\n\nReplace the ui/src/App.tsx file with the following code\n\nBounded code example (external data; do not execute automatically):\n```tsx\n// ui/src/App.tsx\nimport React, { useEffect } from 'react';\nimport {\n  Paper,\n  Stack,\n  Table,\n  TableBody,\n  TableCell,\n  TableContainer,\n  TableHead,\n  TableRow,\n  Typography\n} from \"@mui/material\";\nimport { createDockerDesktopClient } from \"@docker/extension-api-client\";\n\n//obtain docker desktop extension client\nconst ddClient = createDockerDesktopClient();\n\nexport function App() {\n  const [containers, setContainers] = React.useState<any[]>([]);\n\n  useEffect(() => {\n    // List all containers\n    ddClient.docker.cli.exec('ps', ['--all', '--format', '\"{{json .}}\"']).then((result) => {\n      // result.parseJsonLines() parses the output of the command into an array of objects\n      setContainers(result.parseJsonLines());\n    });\n  }, []);\n\n  return (\n    <Stack>\n      <Typography data-testid=\"heading\" variant=\"h3\" role=\"title\">\n        Container list\n      </Typography>\n      <Typograph\n```\n\nScreenshot of the container list.\n\n> [!IMPORTANT] > > We don't have an example for Vue yet.
