This npm package contains a number of regex-based validations as well as string sanetisers that are common in POAP-related dApps.
You can view the complete list of included elements and their documentation here here:
To use this package, install it by running npm i -S @poap/sane-data and using either the regexes or the sanetiser functions.
Example sanetiser usage:
// Import the sanetisers you need
import { sanetise_eth_address, sanetise_ens_address, sanetise_eth_or_ens_address, sanetise_poap_id, sanetise_poap_edit_code, sanetise_email, sanetise_string } from '@poap/sane-data'
// Use the sanetisers in your code
function send_poap( wallet_or_ens, drop_id, email ){
try {
// Sanetise the data
wallet_or_ens = sanetise_eth_or_ens_address( wallet_or_ens )
drop_id = sanetise_poap_id( drop_id )
// Sanetisers throw by default, if you want to continue even when the sanetiser fails, you can disable throwing like so:
email = sanetise_email( email, false )
// Then do whatever you want to do
...
return { success: true }
} catch( e ) {
// The thrown error can be due to invalid values
console.error( `Error doing things:`, e )
return { error: e.message }
}
}Example regex usage:
// Import the regexes you need
import { eth_address_regex, ens_regex, eth_or_ens_address_regex, email_regex, poap_id_regex, poap_edit_code_regex } from '@poap/sane-data'
// Use the regexes
const user_address = `0x0000000000000000000000000000000000000000`
if( user_address.match( eth_address_regex ) ) return 'You qualify for the airdrop'
