generic-json-sanitizer

Generic json sanitizer is very small generic json sanitizer with express middleware support using 'sanitize-html',
by walking on json tree and cleaning any string.


Install via NPM:

``bash

npm install generic-json-sanitizer

`

The sanitizer using sanitize-html API.
And sanitize option is IOptions.

> Pay attention! The async API uses the JS Worker Thread API- this means Node.JS >= 14 is required and may also cause issues with Webpack bundling.
This does NOT affect the synchronous API.

Simple using.

`typescript

import { sanitizeJsonSync } from 'generic-json-sanitizer';

const dirtySchema: any = {
a: 5555,
b: '',
c: {
d: ' world',
{
h: 'hello '
}
]
};

const cleanOptions = {
allowedAttributes: {},
allowedTags: [],
}

/* Clean sync dirty schema /
sanitizeJsonSync(dirtySchema, cleanOptions)
console.log(Sanitized schema: ${JSON.stringify(dirtySchema)});

/* Clean big schema async /
sanitizeJsonAsync(bigDirtySchema, cleanOptions)
.then((sanitizeSchema: any) => {
console.log(Async Sanitized schema sample: ${JSON.stringify(sanitizeSchema[55])});
});

`

Using as express middleware

`typescript
import { sanitizeExpressMiddleware } from 'generic-json-sanitizer';
import * as express from 'express';

const app = express();

/* For default options /
app.use(sanitizeExpressMiddleware);
/* To sanitize big schema, you can use async sanitizer /
app.use(sanitizeExpressMiddlewareAsync);

/* Set 'sanitize-html' options /
app.use((request: express.Request, response: express.Response, next: express.NextFunction) => {
sanitizeExpressMiddleware(request, response, next, {
allowedAttributes: {},
allowedTags: [],
})
});

`


> Async supports only from Node 13.
