In the following examples, we will interact with the coin contract. To have better type support, we strongly recommend generating the type definition from the contract using @kadena/pactjs-cli.

To install @kadena/pactjs-cli as a dev dependency for your project, run the following command in the terminal:

You can generate type definitions from either a local file or directly from the chain.

if your contract has dependency to other modules you should either pass those modules with --file or if they are already deployed on the chain you can use --api to let the script fetch them from the chian. So for the coin example you can alternatively use the following command if you have all of the files locally.

Note: You can use --file and --contract several times, and even together.

Tip: Remember to persist the generated types by adding the command as a npm scripts.
