Implementation Reference

• src/index.ts:370-439 (registration)

  Registration of the 'get_service_example' tool using server.tool, including name, description, input schema, and inline handler function.
  server.tool( "get_service_example", "Get a React Native service example", { service_name: z.string().describe("Service Name"), }, async ({ service_name }) => { if (!service_name) { return { content: [ { type: "text", text: "Service name not specified", }, ], }; } try { // First try exact match const result = getExampleContent("services", service_name); if (result.error) { // Try to find by fuzzy match const servicesDir = path.join(CODE_EXAMPLES_DIR, "react-native", "services"); const closestMatch = findClosestMatch(servicesDir, service_name); if (closestMatch) { const fuzzyResult = getExampleContent("helper", closestMatch); return { content: [ { type: "text", text: fuzzyResult.content?.[0] ?? fuzzyResult.error ?? "Error: No content available", }, ], }; } else { return { content: [ { type: "text", text: `Service ${service_name} not found`, }, ], }; } } return { content: [ { type: "text", text: result.content?.[0] ?? result.error ?? "Error: No content available", }, ], }; } catch (err) { console.error(`Error getting service example ${service_name}:`, err); return { content: [ { type: "text", text: `Error getting service example: ${err}`, }, ], }; } }, );
• src/index.ts:376-438 (handler)

  Inline async handler function that executes the tool logic: checks input, attempts exact match with getExampleContent, falls back to fuzzy match using findClosestMatch, returns markdown content or error.
  async ({ service_name }) => { if (!service_name) { return { content: [ { type: "text", text: "Service name not specified", }, ], }; } try { // First try exact match const result = getExampleContent("services", service_name); if (result.error) { // Try to find by fuzzy match const servicesDir = path.join(CODE_EXAMPLES_DIR, "react-native", "services"); const closestMatch = findClosestMatch(servicesDir, service_name); if (closestMatch) { const fuzzyResult = getExampleContent("helper", closestMatch); return { content: [ { type: "text", text: fuzzyResult.content?.[0] ?? fuzzyResult.error ?? "Error: No content available", }, ], }; } else { return { content: [ { type: "text", text: `Service ${service_name} not found`, }, ], }; } } return { content: [ { type: "text", text: result.content?.[0] ?? result.error ?? "Error: No content available", }, ], }; } catch (err) { console.error(`Error getting service example ${service_name}:`, err); return { content: [ { type: "text", text: `Error getting service example: ${err}`, }, ], }; } },
• src/index.ts:373-375 (schema)

  Input schema using Zod: requires 'service_name' as a string.
  { service_name: z.string().describe("Service Name"), },
• src/index.ts:65-84 (helper)

  Shared helper function called by the handler to load example code content from files in resources/code-examples/react-native/{subcategory} directory.
  function getExampleContent(subcategory: string, filename: string): { content?: string[]; path?: string; error?: string } { const searchDir = path.join(CODE_EXAMPLES_DIR, "react-native", subcategory); const filePath = findFileInSubdirectories(searchDir, filename); if (!filePath || !fs.existsSync(filePath)) { return { error: `Example ${filename} not found` }; } try { const content = fs.readFileSync(filePath, 'utf8'); return { content: [content], path: path.relative(BASE_DIR, filePath) }; } catch (err) { console.error(`Error reading example ${filename}:`, err); return { error: `Error reading example ${filename}` }; } }
• src/index.ts:87-109 (helper)

  Shared helper function called by the handler for fuzzy matching of service names to available example filenames.
  function findClosestMatch(directory: string, searchName: string, extensions: string[] = ['.js', '.jsx', '.ts', '.tsx']) { if (!fs.existsSync(directory)) return null; let closestMatch = null; for (const ext of extensions) { const files = glob.sync(`${directory}/**/*${ext}`); for (const filePath of files) { const fileName = path.basename(filePath); const fileNameNoExt = path.basename(fileName, path.extname(fileName)); if (fileNameNoExt.toLowerCase().includes(searchName.toLowerCase())) { closestMatch = fileNameNoExt; break; } } if (closestMatch) break; } return closestMatch; }
