gimme a couple hours i'll get home and send it app.js:

app.get('/geo/:id', async (c) => {
    let data = await env.visitor.get(`${c.req.param('id')}`);
    console.log(data);
    if (!data) {
        let req = await fetch(`https://api.gapi.io/?key=[...]&i=${c.req.param('id')}`);
        data = await req.json();
        await env.visitor.put(`${c.req.param('id')}`, JSON.stringify(data), { expirationTtl:   172800 });
    } else {
        data = JSON.parse(data);
    }
    return c.json(data);
});

app.get('/geo/:id', async (c) => {
    let data = await env.visitor.get(`${c.req.param('id')}`);
    console.log(data);
    if (!data) {
        let req = await fetch(`https://api.gapi.io/?key=[...]&i=${c.req.param('id')}`);
        data = await req.json();
        await env.visitor.put(`${c.req.param('id')}`, JSON.stringify(data), { expirationTtl:   172800 });
    } else {
        data = JSON.parse(data);
    }
    return c.json(data);
});

kv_namespaces = [{binding = "visitor", id = "...", preview_id = "..."}]

kv_namespaces = [{binding = "visitor", id = "...", preview_id = "..."}]

wrangler.toml: @Leo ah... i was following a diff page on google i'll read the docs n lyk if i got problems do i not need the line in wrangler.toml ?? i got all that by running some wrangler cmds also this line

const app = new Hono<{ Bindings: Bindings }>()

const app = new Hono<{ Bindings: Bindings }>()

does this mean that evertime i restart my api the data will be erased ??

This is for the type or interface for your bindings, type Bindings = { kv: KVNamespace } Your env can be accessed by using c.env

im on js not ts... so what what would this be fr js @gwapes

gwapes•3mo ago

You can only use generics in ts, so ignore it ^

const hono = require('hono').Hono;
const app = new hono();
const { getConnInfo } = require('hono/cloudflare-workers');
const { cors } = require('hono/cors');

app.use('/*', cors());

app.get('/', (c) => c.text('GET /'));
app.get('/geo/:id', async (c) => {
    let data = await c.env.visitor.get(`${c.req.param('id')}`);
    console.log(data);
    if (!data) {
        let req = await fetch(`https://api.gapi.io/?key=[...]&i=${c.req.param('id')}`);
        data = await req.json();
        await c.env.visitor.put(`${c.req.param('id')}`, JSON.stringify(data), { expirationTtl:   172800 });
    } else {
        data = JSON.parse(data);
    }
    return c.json(data);
});

const hono = require('hono').Hono;
const app = new hono();
const { getConnInfo } = require('hono/cloudflare-workers');
const { cors } = require('hono/cors');

app.use('/*', cors());

app.get('/', (c) => c.text('GET /'));
app.get('/geo/:id', async (c) => {
    let data = await c.env.visitor.get(`${c.req.param('id')}`);
    console.log(data);
    if (!data) {
        let req = await fetch(`https://api.gapi.io/?key=[...]&i=${c.req.param('id')}`);
        data = await req.json();
        await c.env.visitor.put(`${c.req.param('id')}`, JSON.stringify(data), { expirationTtl:   172800 });
    } else {
        data = JSON.parse(data);
    }
    return c.json(data);
});
