Using cleos, we can set the permissions like this:

cleos set account permission <your-account> active '{"threshold": 1,"keys": [{"key": "<your-key>","weight": 1}],"accounts": [{"permission":{"actor":<contract-account>,"permission":"eosio.code"},"weight":1}]}' owner -p <your-account>

But can we do the above operation using eosjs?

Basically, pull the existing permission, change only what you need to change, then pass everything back to updateauth ..

async function getNewPermissions(accountName) {
  const account = await eos.getAccount(accountName)
  const perms = JSON.parse(JSON.stringify(account.permissions))
  return perms
}


const perms = await getNewPermissions(accountName)
console.log('New permissions =>', JSON.stringify(perms))
const updateAuthResult = await eos.transaction(tr => {

      for(const perm of perms) {

         tr.updateauth({
             account: accountName,
             permission: perm.perm_name,
             parent: perm.parent,
             auth: perm.required_auth
         }, {authorization: `${accountName}@owner`})

     }
})


console.log('Success =>', JSON.stringify(updateAuthResult));

I hope this will help. Thank You.

In https://github.com/LimeChain/eoslime (uses eosjs behind the scene) there is a addPermission method, which you can use in order to accomplish your aim. It will add a permission for example eosio.code to your active authority.
