gProxy GraphSQL 客户端

如何使用英特尔®oneAPI工具实现PyTorch 优化，直播火热报名中>>>>>>

gProxy 是 SvelteKit 的 GraphSQL 客户端和缓存扩展包。

安装：

npm install --save @leveluptuts/g-query graphql-tag

初始化：

// src/lib/config/g.ts

export const g = new GFetch({
    path: 'https://yourapiurl.com/graphql' //whatever your api url is here
    // More config options coming, for now this is just path to your graphql api
});

添加代码生成器：

// svelte.config.js

import gQueryCodegen from '@leveluptuts/g-query/codegen'

...
vite: {
    plugins: [
        gQueryCodegen({
            // Required
            // schema: 'http://localhost:3001/graphql' // this can also be a url to a graphql api
            schema: './src/lib/graphql/schema.graphql', // path to schema, schema is required
            output: './src/lib/graphql', // Where you want the general schema types to output
            gPath: '$lib/config/g' // Path to g, created in step 1.
            // Optional
            debug: false  // boolean, this adds logging for gq files deleted and on codegen
        })
    ],
}

添加 GraphSQL 文件：

// UserQueries.graphql

query currentUser {
    user {
        _id
    }
}

使用：

<script context="module" lang="ts">
    // The generated function that fetches and caches
    import { getCurrentUser } from './UserQueries.gq';

    export async function load({ fetch }) {
        // Runs the cache/fetch function populating $currentUser before use.
        await getCurrentUser({
            variables: { limit: 0 },
            fetch // Don't forget to pass fetch for ssr
        });
        return {};
    }
</script>

<script lang="ts">
    // Cache becomes populated with data available for SSR
    import { user } from './UserQueries.gq';

    // $: console.log($user.user) //data available for ssr
</script>
