Middleware: Body Parser

[one-aalam]

parseBody (utility/parser)

Add a parseBody(parser) utility that can negotiate the content type of the form submissions, and returns the parsed body

Supports:

• application/json
• application/text
• application/x-www-form-urlencoded
• multipart/form-data (not available in Bun natively)

Example:

// your parsed body
const body = await parseBody(ctx.request!)

Currently, plan to support reading all the content at once and improve it in the future version of the middleware (or when Bun natively supports multipart/form-data

Middleware

As a companion utility, add a body-parser middleware, that attaches the parsed payload to context ctx.body using the above utility.

Supports:
The middleware should support the following multipart/form-data configurations (all optional)

• extensions - supported file extensions (default: all the extensions)
• maxFileSizeBytes - supported maximum payload size per file (default: no restrictions)
• maxSizeBytes - supported maximum payload size for all the files (default: no restrictions)

Example(basic):

import { BunTea } from 'bun-tea'
import { bodyParser } from 'bun-tea/dist/mw/body-parser'

const app = new BunTea()

app.post("/users", [ bodyParser() ], (ctx) => {
    // get your parsed body here...
    // console.log(ctx.body)
    return ctx.json({
        message: "users created",
    });
})

app.listen({
    port: 3000
}, (server) => {
    console.log(`Server started on ${server.port}`)
})

Example(with configuration):

import { BunTea } from 'bun-tea'
import { bodyParser } from 'bun-tea/dist/mw/body-parser'

const app = new BunTea()

app.post("/users", [ bodyParser({
    extensions: ['jpg'],
    maxFileSizeBytes: 2_4000,
    maxSizeBytes: 2_6000
}) ], (ctx) => {
    // get your parsed body here...
    // console.log(ctx.body)
    return ctx.json({
        message: "users created",
    });
})

app.listen({
    port: 3000
}, (server) => {
    console.log(`Server started on ${server.port}`)
})
