Quickly fire up a personal Ethereum blockchain which you can use to run tests, execute commands, and inspect state while controlling how the chain operates. Quickly see the current status of all accounts, including their addresses, private keys, transactions and balances. See the log output of Ganache’s internal blockchain, including responses and other vital debugging information. Configure advanced mining with a single click, setting block times to best suit your development needs. Examine all blocks and transactions to gain insight about what’s happening under the hood. Byzantium comes standard, giving you the latest Ethereum features needed for modern app development. Each platform has an associated npm run configuration to help you build on each platform more easily. Because each platform has different (but similar) build processes, they require different configurations.

node-lambda is a command-line utility for developing, testing, packaging, and deploying Node.js functions to AWS Lambda. It lets developers run Lambda handlers locally with mock event and context data before sending code to AWS. A setup command creates configuration files for events, context, environment variables, deployment settings, and event sources. Packaging can assemble the application and its dependencies into a deployable archive. The deploy command uploads the resulting function while exposing options for runtime, environment, publishing, package management, and other Lambda settings. JavaScript and TypeScript example applications are provided to help users establish a working project quickly. The tool is useful for teams that want a terminal-centered Lambda workflow without manually repeating AWS packaging steps.

dotenvx is an enhanced environment variable loader and manager that builds on the original dotenv concept by adding strong encryption and cross-platform tooling, making it safer to work with .env files in development and production environments. Designed by the creator of the classic dotenv library, dotenvx preserves the familiar workflow while adding safeguards against one of the biggest risks with plain environment files: plaintext secrets exposure. It offers CLI commands that can encrypt and decrypt .env files, inject environment variables at runtime, and support conventions like layered environment file loading similar to Next.js or dotenv-flow. Beyond basic runtime usage, dotenvx includes tooling for key management, listing .env files in structured views, and operations like variable rotation and scoped overrides, bringing more robust secrets handling to modern app stacks.
