Fastify plugin that adds content type parser for the application/x-www-form-urlencoded and/or multipart/form-data types
Fastify plugin that adds content type parser for the application/x-www-form-urlencoded
and/or multipart/form-data
types.
Essentially a tiny wrapper around busboy, that parses application/x-www-form-urlencoded
and/or multipart/form-data
content types and attaches associated fields to request.body
.
NB! This plugin does not handle files
, these get simply discarded as described here.
npm install fastify-simple-form
Although this package includes typings for the plugin itself, you must install ones for node.js and busboy manually:
npm install @types/node @types/busboy --save-dev
fastify.register(require('fastify-simple-form'), {
multipart: true, // Enable parsing for `multipart/form-data`, default: true
urlencoded: false, // Disable parsing for `application/x-www-form-urlencoded`, default: true
});
This plugin has no effect when both options above are set to false
!
Accepts identical options to those of busboy constructor (with the exception of headers
), e.g.:
fastify.register(require('fastify-simple-form'), {
defCharset: 'utf8',
limits: {
fieldNameSize: 100, // Max field name size (in bytes), default: 100
fieldSize: 1000000, // Max field value size (in bytes), default: 1MB
fields: 10, // Max number of non-file fields, default: Infinity
},
});
Given server & handler:
import Fastify from 'fastify';
import SimpleFormPlugin from 'fastify-simple-form';
const fastify = Fastify();
fastify.register(SimpleFormPlugin);
fastify.post(
'/token',
{
schema: {
body: {
type: 'object',
properties: {
username: {
type: 'string',
},
password: {
type: 'string',
},
client_id: {
type: 'string',
format: 'uuid',
},
client_secret: {
type: 'string',
},
refresh_token: {
type: 'string',
format: 'uuid',
},
grant_type: {
type: 'string',
enum: ['authorization_code', 'refresh_token'],
},
},
required: ['grant_type'],
},
},
},
(request, reply) => {
reply.send(request.body);
},
);
fastify.listen(3000);
These requests would succeed:
curl \
-F "client_id=e52b2864-7611-4f26-94e4-d13f7039f25d" \
-F "client_secret=rGGb45-awp0Q9X2yP3CxwhP8HhUY8uW1" \
-F "refresh_token=f5e6ca6e-e2cf-4130-9b3f-26727ca11f78" \
-F "grant_type=refresh_token" \
localhost:3000/token
curl \
-d "client_id=e52b2864-7611-4f26-94e4-d13f7039f25d" \
-d "client_secret=rGGb45-awp0Q9X2yP3CxwhP8HhUY8uW1" \
-d "refresh_token=f5e6ca6e-e2cf-4130-9b3f-26727ca11f78" \
-d "grant_type=refresh_token" \
localhost:3000/token
Response:
{
"client_id": "e52b2864-7611-4f26-94e4-d13f7039f25d",
"client_secret": "rGGb45-awp0Q9X2yP3CxwhP8HhUY8uW1",
"refresh_token": "f5e6ca6e-e2cf-4130-9b3f-26727ca11f78",
"grant_type": "refresh_token"
}
While these won't pass the schema validation
curl \
-F "username=jon" \
-F "password=snow" \
-F "grant_type=password" \
localhost:3000/token
curl \
-d "username=jon" \
-d "password=snow" \
-d "grant_type=password" \
localhost:3000/token
Response
{
"statusCode": 400,
"error": "Bad Request",
"message": "body.grant_type should be equal to one of the allowed values"
}
