Steem-js And Hivejs Simultaneously
I wrote many scripts that worked with Steem. After The Fork, I tried to use steem-js and hivejs in the same program but it doesn't work.
I found an easy solution. I use only one javascript library and change just the endpoint, while not doing simultaneous asynchronous requests on both blockchains.
Then Blurt arrived. More easy change was required: chain_id, address_prefix, currency symbol.
HF24 Changes
Soon the Hive hard fork 24 with the chain ID change will take place on October 6, 2020, 14:00 UTC.
Here is a snippet similar to the code I use to switch the bockchains:
const chain=require("hive"); // also works with "steem" or "@blurtfoundation/blurtjs"
if (name=='steem') {
chain.api.setOptions({ url: 'https://api.steemit.com' });
chain.config.set('address_prefix','STM');
chain.config.set('chain_id','0000000000000000000000000000000000000000000000000000000000000000');
chain.config.set('alternative_api_endpoints', ['https://api.steemit.com', 'https://api.steemit.com']);
} else if (name=='hive') {
chain.api.setOptions({ url: 'https://anyx.io' });
chain.config.set('address_prefix','STM');
if (new Date().getTime()>=new Date("2020-10-06T14:00:00").getTime()) {
chain.config.set('chain_id','beeab0de00000000000000000000000000000000000000000000000000000000');
} else {
chain.config.set('chain_id','0000000000000000000000000000000000000000000000000000000000000000');
}
chain.config.set('alternative_api_endpoints', ['https://api.hive.blog', 'https://anyx.io']);
} else if (name=='blurt') {
chain.api.setOptions({ url: 'https://rpc.blurt.world/', useAppbaseApi: true });
chain.config.set('address_prefix','BLT');
chain.config.set('chain_id','cd8d90f29ae273abec3eaa7731e25934c63eb654d55080caff2ebb7f5df6381f');
chain.config.set('alternative_api_endpoints', ['https://rpc.blurt.buzz', 'https://api.blurt.blog']);
}
You can't make asynchronous requests to more than one blockchain simultaneously.
An Implementation
Don't hesitate to make use of the Free Hive Voting Service, working on the 3 blockchains.
