Summary: - Upgrades to build-related packages: - Upgrade typescript, related libraries and typings. - Upgrade webpack, eslint; add tsc-watch, node-dev, eslint_d. - Build organization changes: - Build webpack from original typescript, transpiling only; with errors still reported by a background tsc watching process. - Typescript-related changes: - Reduce imports of AWS dependencies (very noticeable speedup) - Avoid auto-loading global @types - Client code is now built with isolatedModules flag (for safe transpilation) - Use allowJs to avoid copying JS files manually. - Linting changes - Enhance Arcanist ESLintLinter to run before/after commands, and set up to use eslint_d - Update eslint config, and include .eslintignore to avoid linting generated files. - Include a bunch of eslint-prompted and eslint-generated fixes - Add no-unused-expression rule to eslint, and fix a few warnings about it - Other items: - Refactor cssInput to avoid circular dependency - Remove a bit of unused code, libraries, dependencies Test Plan: No behavior changes, all existing tests pass. There are 30 tests fewer reported because `test_gpath.py` was removed (it's been unused for years) Reviewers: paulfitz Reviewed By: paulfitz Subscribers: paulfitz Differential Revision: https://phab.getgrist.com/D3498
