`@appium/schema` is a package which was extracted from `appium`. It _only_ contains the schema. The impetus here was to avoid cyclical dependencies, since `appium` depends on `@appium/types`, and `@appium/types` depends on the schema. This package breaks the cycle.
The `scripts/generate-schema-json.js` (which converts the compiled JS schema file into JSON) has moved into this package, and the generated JSON file is now under version control. This is because the `generate-schema-types.js` script (previously `generate-schema-declarations`) depends on it, and `@appium/types` depends on the generated types. The generated types are _also_ under version control. I do not expect the schema to change often, so I believe the tradeoff to be worth it.
## @appium/schema
`lib/appium-config-schema.js` is the "single source of truth" for the schema.
## appium
- Removed schema source
- Removed namespaces from internal types because they suck (see change to `types/index.d.ts`)
- Removed unused `continuation-local-storage`
- Add dep for `@appium/schema`
- Added a TS project dependency on `@appium/schema`
## @appium/types
- The "sources" have moved from `src` to `lib` for consistency.
- `lib/appium-config.ts` (the generated types) are now under version control.
- `lib/schema/` has been removed (it previously held the JSON schema artifact)
- `scripts/generate-schema-declarations.js` becomes `scripts/generate-schema-types.js`
- Updated scripts in `package.json`
- Added dep for `@appium/schema`
- Added a TS project dependency on `@appium/schema`
## Other
- Reorganize root `tsconfig.json`; add `schema` reference; remove unused `noEmit: true`
- Sort root `package.json`
- Remove schema JSON and schema declarations scripts, since those are now both handled in their respective packages
- Remove `lint-staged` config for schema file, since it didn't work right anyway (still need to do something about this, but probably doesn't need to be in a precommit hook)
- Remove stuff from `.gitignore`
This will be run before publish, and will copy the root `LICENSE` file to all packages, so that they appear in the published tarballs.
`packages/*/LICENSE` are ignored by Git, since they are redundant with the root `LICENSE` file.
This changes the TS configuration to to a) emit declarations for supported packages, and b) build declarations incrementally by package.
To begin, we are targeting `appium`, `@appium/base-driver` and `@appium/support` for declarations; these three are intended to be published with declarations generated via their JS.
Both `@appium/support` and `appium` are fully typechecked (sans implicit `any` types), but `@appium/base-driver` is mostly not. Regardless, declarations are generated for all three.
Each package will have its own `tsconfig.json` which "inherits" from `config/tsconfig.base.json`. Each will also need to declare relative paths to dependencies. e.g., the `appium` package must configure its `tsconfig.json` so that it depends on the declarations of `@appium/support` and also where to find `@appium/support`. Essentially, a small dependency tree gets built, and those at the "root" get their declarations built first; then the consumers use those declarations.
Also reorganized some scripts and added `npm-run-all` to help and added a "typecheck" job to CI.
Since `npm install` will build, it's pretty inconvenient to have `npm` abort installation if the build fails. In that case, if any of the build steps fail (see `build:loose`) the installation will continue. Added a `prepublishOnly` which runs a build in "strict" mode where everything must pass.
_Note: there's still a strong coupling of "what `BaseDriver` provides" and "what an external driver *may* provide". It's unclear to me if this is a problem, though there seem to be a handful of methods that external drivers *must* implement. The easiest way to get around this would probably be to extract these required properties and methods into their own interface (duplication) if we cannot otherwise declare methods as "abstract". As it stands, the `Driver` is basically just `BaseDriver`._
Also:
- Moved some configuration types out of `appium` and into here, since they are used both by `appium` and `base-driver` via `DriverOpts`
- Split `Driver` type into "the thing that BaseDriver is" and "all the other methods external drivers can implement"
- Added missing `proxyCommand` method
- Better generics for `LogType`
- Remove unused `Constructor` type
- Better types for `getSession`/`getSessions`
- Added util `Class` type
- Added many missing typings from DefinitelyTyped
- Added `ts-node` for `@wdio/types` (I need to send a PR to webdriver to eliminate this dependency)
- Type checks in their CI step
This change removes `gulp` and replaces it with plain ol' `babel` and `mocha`.
## `appium`
- No gulp.
- `test/` has been re-organized. All test files now end in the extension `.spec.js`, which is a recognized convention and understood by editors/IDEs. The tests are further split into `unit` and `e2e` subdirs. This makes working with both `babel` and `mocha` easier.
- The tests are _not_ run against the transpiled code; code is now transpiled on-the-fly via `@babel/register`. This only affects `appium`.
- `commands-yml/validator.js` moved to `scripts/parse-yml-commands.js`. It has been rewritten as a CJS module. `commands-yml/` should not contain `.js` files.
- `test/setup.js` is a new test harness specific to Appium, which loads & configures `@babel/register`. Eventually, the contents of this file can be moved into the root monorepo's `test/setup.js`, but the rest of the packages do not need `@babel/register`, so we avoid the overhead.
## `@appium/gulp-plugins`
- Unfortunately, due to the new `npm test` strategy (see below), we cannot use the `nyan` reporter. Or rather, we _can_, but will not see the animation. So the reporter is now set to default to `spec`.
- Modified tests so they didn't overwrite the actual `build` dir with transpiled fixtures, which is what was happening. This was causing failures depending on the transpile/test order.
## All Packages
- All packages now have their own `build`, `test`, `test:e2e` and `dev` (just build + watch mode) npm scripts. This makes running a complete build easier, since each package can now provide its own appropriate command. This is _mostly_ just `gulp once` (where `gulp` was used before), except for `appium`, where `@babel/cli` is used directly.
- This is what happens when `npm test` is run from the monorepo (in order):
1. All packages are built (in parallel) by running `npm run build` in each folder (via `lerna`). See `pretest`
2. All code is linted directly via `eslint`.
3. All _unit tests_ are run w/ `npm test` in each folder, having assumed transpilation already occurred (if necessary).
- `npm run e2e-test` runs the `npm run test:e2e` in each folder. No transpilation occurs! Careful.
- All scripts are expected to live in `packages/*/scripts`, and this directory enforces CJS via ESLint. `postinstall.js` moved, as well as `check-npm-pack-files.js`. `generate-schema-declarations.mjs` moved from the root `scripts/` dir into `packages/appium/scripts/`; it's now CJS instead of ESM.
- I had profiled running various things with `lerna run --parallel`, but it turns out this is not faster. I'm not sure why, but I think it may have something to do with streaming STDOUT/STDERR, or potentially the overhead of running child processes outweighs the time it takes to actually run tests and builds.
- The behavior of `lerna run` now mimicks `lerna exec`, which was "run stuff in serial, streaming the output". The default behavior of `lerna run` is "run stuff in parallel, buffering the output". Buffered output sucks, and streaming the output from all tasks at once creates chaos. To override this behavior, you'll see `--parallel --concurrency=8 --prefix` for tasks that can truly be parallelized, like transpilation. The number 8 is the "maximum", and CI usually won't have more than 2 cores available anyway.
- When run in CI, Mocha runs with `--forbid-only`, which will fail if there's an `.only()` somewhere in the tests. Further, it forces color output.
## Etc.
- Updated Wallaby config, `.gitignore`, `.eslintignore`.
- Sorted `package.json` files
- Removed `watch` and `coverage` scripts which were broken anyway.
chore(appium): fix schema json path issues
- the path to the JSON schema is now correct: `lib/appium-config-schema.json`
- add `log-symbols` to devdeps for niceness. this is already a transitive dep
- Upgrade TS to `next` tag. It's "safe" to use using bleeding-edge TS here since we don't actually use it to compile anything
- Add a bunch of missing types: `find-root`, `klaw`, `lockfile`, `mv`, `ncp`, `rimraf`
