migrate aio to eslint as tslint has been deprecated, the migration is restricted to the aio app and
its e2e tests and does not include the other tools, for such reason both tslint and codelyzer have not
been removed (to be done in a next PR)
some minor tweaks needed to be applied to the code so that it would adhere to the new ESLinting behaviour
most TSLint rules have been substituted with their ESLint equivalent, with some exceptions:
* [whitespace] does not have an ESLint equivalent (suggested to be handled by prettier)
* [import-spacing] does not have an ESLint equivalent (suggested to be handled by prettier)
* [ban] replaced with [no-restricted-syntax] as there is no (official/included) ESLint equivalent
some rules have minor different behaviours compared to their TSLint counterparts:
* @typescript-eslint/naming-convention:
- typescript-eslint does not enforce uppercase for const only.
* @typescript-eslint/no-unused-expressions:
- The TSLint optional config "allow-new" is the default ESLint behavior and will no longer be ignored.
* arrow-body-style:
- ESLint will throw an error if the function body is multiline yet has a one-line return on it.
* eqeqeq:
- Option "smart" allows for comparing two literal values, evaluating the value of typeof and null comparisons.
* no-console:
- Custom console methods, if they exist, will no longer be allowed.
* no-invalid-this:
- Functions in methods will no longer be ignored.
* no-underscore-dangle:
- Leading and trailing underscores (_) on identifiers will now be ignored.
* prefer-arrow/prefer-arrow-functions:
- ESLint does not support allowing standalone function declarations.
- ESLint does not support allowing named functions defined with the function keyword.
* space-before-function-paren:
- Option "constructor" is not supported by ESLint.
- Option "method" is not supported by ESLint.
additional notes:
* the current typescript version used by the aio app is 4.3.5, which is not supported by typescript-eslint (the supported
versions are >=3.3.1 and <4.3.0). this causes a warning message to appear during linting, this issue should
likely/hopefully disappear in the future as typescript-eslint catches up
* The new "no-console" rule is not completely equivalent to what we had prior the migration, this is because TSLint's "no-console"
rule let you specify the methods you did not want to allow, whilst ESLint's "no-console" lets you specify the methods that you do
want to allow, so and in order not to have a very long list of methods in the ESLint rule it's been decided for the time being
to simply only allow the "log", "warn" and "error" methods
* 4 dependencies have been added as they have been considered necessary (see: https://github.com/angular/angular/pull/42820#discussion_r669978232)

* the migration has been performed by following: https://github.com/angular-eslint/angular-eslint#migrating-an-angular-cli-project-from-codelyzer-and-tslin

This commit upgrades `lighthouse` to the latest version (8.1.0) to take
advantage of latest fixes/improvements and ensure the min scores are
still met with the latest audit changes.

Update `@angular/*` packages to latest 12.1.x versions (mainly to take
advantage of recent ServiceWorker improvements, such as #42607
and #42622).

Updates to TypeScript 4.3.4 which contains a fix for a printer
regression that caused unexpected JavaScript output with our
compiler transforms.

PR Close#42600
Switches the repository to TypeScript 4.3 and the latest
version of tslib. This involves updating the peer dependency
ranges on `typescript` for the compiler CLI and for the Bazel
package. Tests for new TypeScript features have been added to
ensure compatibility with Angular's ngtsc compiler.

[`watchr` v4.0.0][1] changes the way watched directories are
scanned/watched, thus causing a great increase in the consumed CPU and
RAM. This affects the performance of the `docs-watch` and transitively
`serve-and-sync` npm scripts.
(For reference, on my local machine it goes from 0% CPU and 275MB RAM
with v3.0.1 to 50% CPU and 10GB RAM with v4+.)
This commit pins `watchr` to version 3.0.1 (which is the latest version
that does not cause performance issues) and disabled automatic updates
via Renovate.

With this change we add the `assert` polyfill which is required because `timezone-mock` is a Node.JS library which is being used in Browser.

This is a temporary workaround until the CLI version containing a fix for the regression caused by deacc74 is available on NPM.
Without this change CLI builds will fail with;
```
angularCompiler.getNextProgram is not a function
```

With this change we update several dependencies to avoid Renovate creating a lot of PRs during onboarding. We also remove yarn workspaces as after further analysis these are not needed.
Certain dependencies such as `@octokit/rest`, `remark` and `@babel/*` have not been updated as they require a decent amount of work to update, and it's best to leave them for a seperate PR.

The AIO search index is built in a WebWorker on the browser from a set
of page information that is downloaded as a JSON file (`search-data.json`).
We want to keep this file as small as possible while providing enough
data to generate a useful index to query against.
Previously, we only included one copy of each (non-ignored) term from each
doc but this prevents more subtle ranking of query results, since the number
of occurences of a term in a doc is lost.
This commit changes the generated file in the following ways:
- All non-ignored terms are now included in the order in which they appear
in the doc.
- The terms are indexed into a dictonary to avoid the text of the term being
repeated in every doc that contains the term.
- Each term is pre-"stemmed" using the same Porter Stemming algorith that the
Lunr search engine uses.
The web-worker has been updated to decode the new format of the file.
Now that all terms are included, it may enable some level of phrase based
matching in the future.
The size of the generated file is considerably larger than previously, but
on production HTTP servers the data is sent compressed, which reduces the
size dramatically.
