# Lite weight nodejs service to build transaction
Can run on aws serverless lambda or on a server with `npm run dev`;
I suggest trying lambda because it's free.
### Based on:
- [ergoscript.js](https://github.com/nirvanush/ergoscript) - transaction builder library
- [isomorphic-wallet](https://github.com/nirvanush/isomorphic-wallet) - in code wallet with same api as dapp connector.
## How to start
```
git clone https://github.com/nirvanush/txbuilder-service
cd txbuilder-service
npm i
npm run start
Will run on port 5008
```
## How to use:
Use the tx configuration syntax as described it [ergoscript.js](https://github.com/nirvanush/ergoscript) README.md;
Here is the example of generating a simple transaction of sending 5 Comet:
```
const response = await fetch('yourhost.com/build_tx', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
"config": [{
"funds": {
"ERG": 10000000,
"tokens": [{
"tokenId": "0cd8c9f416e5b1ca9f986a7f10a84191dfb85941619e49e53c0dc30ebf83324b",
"amount": 5
}]
},
"toAddress": "",
"additionalRegisters": {
value: '40', type: 'Int'
}
}],
"userAddress": await ergo.get_change_address() // this is the public address of user that will have to sign this tx later.
})
}).then(resp => resp.json());
const { unsignedTx } = response;
// later you can sign this tx using dapp connector
// and submit
const signedTx = ergo.sign_tx(unsignedTx)
const hash = ergo.submit_tx(signedTx);
```
### TODO:
- Custom explorer endpoint, currently using public.
