npm install
npm run gen-desc
To run the node , you at least need
- satotx support
- Make sure you have the sCrypt(0.6.1) Visual Studio Extension installed. Here is a example for config
src/config/signer.json
{
"default": {
"satotxApiPrefix": "https://api.satotx.com",
"satotxPubKey": "25108ec89eb96b99314619eb5b124f11f00307a833cda48f5ab1865a04d4cfa567095ea4dd47cdf5c7568cd8efa77805197a67943fe965b0a558216011c374aa06a7527b20b0ce9471e399fa752e8c8b72a12527768a9fc7092f1a7057c1a1514b59df4d154df0d5994ff3b386a04d819474efbd99fb10681db58b1bd857f6d5"
},
"production": {
"satotxApiPrefix": "https://api.satotx.com",
"satotxPubKey": "25108ec89eb96b99314619eb5b124f11f00307a833cda48f5ab1865a04d4cfa567095ea4dd47cdf5c7568cd8efa77805197a67943fe965b0a558216011c374aa06a7527b20b0ce9471e399fa752e8c8b72a12527768a9fc7092f1a7057c1a1514b59df4d154df0d5994ff3b386a04d819474efbd99fb10681db58b1bd857f6d5"
}
}
and then just run
node src/app.js
or run in production
node src/app.js env=production
