Enable Typescript checking on ./client folder (https://github.com/woocommerce/woocommerce-admin/pull/8372) * Copied .tsconfig into ./client to enable ts checking - Made sub-repos composite typescript packages where necessary * Prevent tsc from transpiling ./client - we use webpack for transpiling so no need for this * Added tsc resolution path for @automattic/explat-client - Seems like there's a type export issue (?) with @automattic/explat-client and @automattic/explat-client-react-helpers - adding the node_modules/@automattic/explat-client path in tsconfig seems to help TS resolve this using the source .ts files - found answer here: https://github.com/microsoft/TypeScript/issues/42873 - should figure out what's actually wrong with the type exports and fix that there instead * Removed mandatory checking from webpack - removed this for now as it will block all development until all type inconsistencies are fixed - for now, run the optional ts:check task either in console or vscode for highlighting type errors * Added vscode tasks for typescript checking * Patch @automattic/explat-client-react-helpers - this changes the installed code in node_modules (post-installation) for @automattic/explat-client-react-helpers so that it exports the necessary type interfaces required by us - attempted unsuccessfully to override type exports using declare module - not too sure how to fix this internally by other means - have to investigate what fixes to propose to @automattic/explat-client-react-helpers team * changed tests in ./client to use ts-jest instead of babel-jest - rewrote jest config to use ts-jest instead of babel-jest - set ts errors to warnings instead so that tests don't fail on type errors - created new tsconfig for ./packages/js-tests so that build and ts-check are separate, as js-tests need to be built for commonjs
