Readme
Who among us wasn't frustrated by the fact that everytime the request has a query parameter in the url like isLast=1
or isLast=true
, you should write extra code by yourself to convert that string "1" or "true" to a boolean true
value.
Here comes booleanize-query-express
to the rescue!
npm install booleanize-query-express
Once the package is installed in node_modules, you can use it simply
import express from 'express';
import {booleanize} from 'booleanize-query-express';
const app = express();
If no options are passed in booleanize(..),
then booleanize will consider that all of the query parameters starting with ["is", "has", "are", "can", "should"]
are boolean query params.
app.use(booleanize());
To override the default startingWith
options, you can do the following:
// app.use(booleanize({startingWith: ["has","in","are"]}))
in this case, only query params starting with 'has', 'in' and 'are' will be treated as boolean variables (overrides the default one)
Now the essential part:
app.get('/test?isValid=true&isNew=1&hasJob=0&somethingElse=false',(req: Request, res: Response) => {
const {isValid, isNew, hasJob, somethingElse} = req.query;
console.log(isValid === true); // true
console.log(isNew === true); // true
console.log(hasJob === false); // true
console.log(somethingElse === "false"); //true, because somethingElse doesn't start with 'is' or 'has'
return res.json(req.query);
})
import express from 'express';
import {booleanize} from 'booleanize-query-express';
const app = express();
app.use(booleanize());
// app.use(booleanize({startingWith: ["has","in","are"]}))
app.get('/test?isValid=true&isNew=1&hasJob=0&somethingElse=false',(req: Request, res: Response) => {
const {isValid, isNew, hasJob, somethingElse} = req.query;
console.log(isValid === true); // true
console.log(isNew === true); // true
console.log(hasJob === false); // true
console.log(somethingElse === "false"); //true, because somethingElse doesn't start with 'is' or 'has'
return res.json(req.query);
})
All query params variable must be camelCased, or else, even if they start with "is","has", or whatever prefix in the provided or default array, the middleware will not convert them to boolean, and they will remain as string.
isBlabla=true // Correct ✔️ isBlabla -> true
isblabla=true // Incorrect ❌ isblabla -> "true"
