## 前提条件 [#前提条件]
* SvelteKit 项目
* Firecrawl API 密钥 — [免费获取一个](https://www.firecrawl.dev/app/api-keys)
## 安装 SDK [#安装-sdk]
```bash
npm install firecrawl
```
将 API 密钥添加到 `.env`：
```bash
FIRECRAWL_API_KEY=fc-YOUR-API-KEY
```
## 进行网页搜索 [#进行网页搜索]
在 `src/routes/search/+page.server.ts` 中创建表单 action：
```typescript
import { Firecrawl } from "firecrawl";
import { FIRECRAWL_API_KEY } from "$env/static/private";
const firecrawl = new Firecrawl({ apiKey: FIRECRAWL_API_KEY });
export const actions = {
default: async ({ request }) => {
const data = await request.formData();
const query = data.get("query") as string;
const results = await firecrawl.search(query, { limit: 5 });
return { results: (results.web || []).map((r) => ({ title: r.title, url: r.url })) };
},
};
```
在 `src/routes/search/+page.svelte` 中完成接入：
```svelte
{#if form?.results}
{#each form.results as result}
{/each}
{/if}
```
## 抓取页面 [#抓取页面]
在 `src/routes/scrape/+page.server.ts` 的 `load` 函数中获取数据：
```typescript
import { Firecrawl } from "firecrawl";
import { FIRECRAWL_API_KEY } from "$env/static/private";
const firecrawl = new Firecrawl({ apiKey: FIRECRAWL_API_KEY });
export async function load({ url }) {
const target = url.searchParams.get("url");
if (!target) return { markdown: null };
const result = await firecrawl.scrape(target);
return { markdown: result.markdown };
}
```
在 `src/routes/scrape/+page.svelte` 中显示它：
```svelte
{#if data.markdown}
{data.markdown}
{:else}
Pass ?url= to scrape a page
{/if}
```
## 与页面交互 [#与页面交互]
在 `src/routes/api/interact/+server.ts` 中创建一个服务端端点：
```typescript
import { json } from "@sveltejs/kit";
import { Firecrawl } from "firecrawl";
import { FIRECRAWL_API_KEY } from "$env/static/private";
const firecrawl = new Firecrawl({ apiKey: FIRECRAWL_API_KEY });
export async function POST() {
const result = await firecrawl.scrape("https://www.amazon.com", {
formats: ["markdown"],
});
const scrapeId = result.metadata?.scrapeId;
await firecrawl.interact(scrapeId, {
prompt: "Search for iPhone 16 Pro Max",
});
const response = await firecrawl.interact(scrapeId, {
prompt: "Click on the first result and tell me the price",
});
await firecrawl.stopInteraction(scrapeId);
return json({ output: response.output });
}
```
