Video

Topics covered

  • Installation of libraries.
  • Installation of dependencies: xrpl-client and xrpl-accountlib.
  • Transpile Typescript code to JavaScript.

Some people are getting errors like:

"TypeError: AddressCodec.isValidSeed is not a function" error.

var Keypair = ripple_keypairs_1.default.deriveKeypair(familyseed); 
TypeError: Cannot read properties of undefined (reading 'deriveKeypair')

Solution: Install the latest versions of the dependency libraries:

npm install xrpl-accountlib@latest xrpl-client@latest --save

TypeScript Error

- error TS7016: Could not find a declaration file for module 'ripple-secret-codec'. '/Users/Satish//XRPL-JS-TS-demo/node_modules/ripple-secret-codec/ripple-secret-codec.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/ripple-secret-codec` if it exists or add a new declaration (.d.ts) file containing `declare module 'ripple-secret-codec';`

10 import * as rippleSecretCodec from "ripple-secret-codec";

Solution: Run this command

npm i --save-dev @types/ripple-secret-codec

Possible Error

If you get error(bash: tsc: command not found) while running tsc -w, then please use this command(in the command prompt) to first install typescript: npm install typescript -g

Note

If you are a windows user and you do not have Git tools, you can directly download “XRPL JS TS” package from Github. Please refer the image below to find the download link.

💡
Final tip: Keep tsc -w running so that it transpiles the Typescript files to Javascript.
