Walkthrough

This PR adds support for the Monad blockchain network, defaults language selection to TypeScript instead of interactive prompts, and introduces ReScript template configuration files. Network tiering is updated to classify Monad as Gold tier.

Changes

Cohort / File(s)	Change Summary
Monad Network Support codegenerator/cli/CommandLineHelp.md, codegenerator/cli/src/config_parsing/chain_helpers.rs	Adds Monad (143) as a new network enum variant with Gold-tier classification in threshold and HypersyncNetwork tier logic; replaces monad-testnet with monad in CLI help documentation.
Language Selection Defaults codegenerator/cli/src/cli_args/interactive_init/mod.rs, codegenerator/cli/src/executor/init.rs	Removes interactive language prompts and defaults to Language::TypeScript in both modules; template extraction now uses fixed TypeScript language; error messages simplified to omit language details.
ReScript Templates codegenerator/cli/templates/static/blank_template/rescript/rescript.json, codegenerator/cli/templates/static/blank_template/rescript/test/Test.res	Adds new ReScript project configuration file with CommonJS module system and standard dependencies; adds ReScript test module with imports for Mocha, Belt, and TestHelpers.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Verify that Monad being classified as Gold tier aligns with intended block confirmation thresholds
• Confirm that hardcoding TypeScript in template extraction does not break EVM or Fuel template generation workflows
• Check that ReScript template files are syntactically valid and properly integrated with the blank template structure

41-53: Template extraction now ignores requested language and forces TypeScript

Both Fuel and EVM Template init flows now call get_and_extract_template with &Language::TypeScript, regardless of init_config.language, and the error context no longer mentions language. This is fine if templates are intentionally TS‑only, but it means envio init ... --language rescript plus a template choice will still extract the TypeScript template.

If TS‑only templates are the goal, consider either:

• Rejecting or warning on --language rescript when a template is selected, or
• Clarifying in CLI help/docs that EVM/Fuel templates are currently TS‑only.

Otherwise, if ReScript templates are expected here, this call should probably respect init_config.language instead of forcing TypeScript.

109-109: Blockchain option list: Monad entries look consistent

The blockchain possible values now include both monad and monad-testnet in the expected kebab‑case and ordering; this matches the Network enum naming and looks good.

1-3: ReScript blank test stub looks fine; just ensure dependencies exist

This is a reasonable minimal test entrypoint for the ReScript blank template; as long as RescriptMocha and TestHelpers are available in the generated project, it should compile and run.

It’s worth generating a new ReScript blank project and running pnpm rescript followed by pnpm mocha to confirm the scaffold builds and tests execute as expected. Based on learnings, this matches the usual verification flow.

140-143: Defaulting missing language to TypeScript simplifies init behavior

Using Language::TypeScript when init_args.language is None removes the interactive language prompt and makes the default explicit, which should reduce friction in common cases.

Please confirm that this matches the intended UX (i.e., that it’s acceptable for envio init to silently choose TypeScript when -l/--language is omitted, and that docs/examples don’t still suggest an interactive language choice).

codegenerator/cli/templates/static/blank_template/rescript/rescript.json (1)

1-27: ReScript blank template config looks sensible

The rescript.json (bsconfig) for the blank ReScript template has a reasonable project name, sources (src and test with subdirs), CommonJS in‑source build, JSX v4, .res.js suffix, and expected bs-dependencies. It should work well as a scaffold.

Please double‑check that:

• The generated project’s package.json pulls in generated, envio, and rescript-schema correctly, and
• Your build/test flow (pnpm rescript then pnpm mocha) succeeds using this config on a freshly generated ReScript blank project.

260-265: Monad network wiring and tiering look internally consistent

Adding Monad = 143 with HypersyncNetwork/NetworkWithExplorer subenum membership, including it in the DEFAULT_CONFIRMED_BLOCK_THRESHOLD group, and classifying both Monad and MonadTestnet as Gold in HypersyncNetwork::get_tier all look coherent and preserve the enum’s alphabetical ordering constraints.
