❗ Remember to setup transform-hub locally or use the platform's environment for the sequence deployment.

Open the terminal and run the following commands:

# go to 'mediawiki' directory cd typescript/mediawiki # install dependencies npm install # transpile TS->JS to dist/ npm run build # deploy the Sequence from the dist/ directory, which contains transpiled code, package.json and node_modules si seq deploy dist # See output si inst output - # Check console.log messages si inst stdout - # Check console.error messages si inst stderr - # Send event, e.g. `drain`: `si inst emit <instance-id> drain "{}"` si inst event emit - <event> <payload>

💡NOTE: Command deploy performs three actions at once: pack, send and start the Sequence. It is the same as if you would run those three commands separately:

si seq pack dist/ -o mediawiki.tar.gz # compress 'dist/' directory into file named 'mediawiki.tar.gz' si seq send mediawiki.tar.gz # send packed Sequence to STH, this will output Sequence ID si seq start - --args [\"<search>\"] # start the Sequence, this will output Instance ID. Search is optional and can be used to filter out results, e.g. "data.server_name === ''"
