Currently, the only place that we use `lodash` in the entire `apollo-server`
repository is to utilize the `sortBy` function in this signature generation.
Looking at the bundle stats, it appears that lodash represents 7.1% of the
`apollo-server` package. We're a server, so bundle size is generally less
of a concern, but it's still not to be ignored, particularly as we move into
worker environments. More pressingly though, since this package will be
utilized by the `apollo` CLI, we'll be shaving precious download time off
the invocation of `npx apollo` if we can get this down.
By switching to the modular package (but still depending on `@types/lodash`
for _just_ the `ListIteratee` type — which we only need in development — we
should be able to trim 55.4kB minified (19.1kB minified+gzip'd) off the
`apollo-server` build.

These AST visitors and transformations are more generally usable for other
purposes rather than just the Apollo Engine signature reporting and would
seem to belong in a module of their own.
Many of these signature calculation functions are now utilized in tools or
helpers which are not directly related to `apollo-server` functionality,
including various aspects of the `apollo` CLI which live within
`apollo-tooling`.
Currently, because of `apollo`'s dependency on `apollo-engine-reporting` for
this signature, this requires bringing in the entire dependency tree which
`apollo-server-core` relies on since `apollo-engine-reporting` depends on
`apollo-server-core`.
By moving this into this new `apollo-graphql` utility library, we're able to
trim that rather hefty dependency tree and drastically reduce the download
for running, say, `npx apollo`.
* Remove `willStart` from `apollo-server`, already called via `...-express`.
When the request pipeline was initially introduced, the integrations
had yet to be updated to call the new life-cycle events. Now, the
integrations have all caught up, but `apollo-server` is still calling
`willStart`, despite the fact that its dependency which provides the actual
server implementation — `apollo-server-express` – is _also_ calling it,
resulting in double invocation of this event.
I suspect some follow-up work should guard against this possibility, but for
now this should remove the duplication.
* Update CHANGELOG.md for #2239.
Ref: https://github.com/apollographql/apollo-server/pull/2239
This is consistent with the old engineproxy interpretation of cache hints. We
special-case scalar fields to inherit their parent field's hints for
simplicity (so you don't have to hint every scalar field in a hinted object),
but when the parent field is non-root that inherited hint gets defaultMaxAge
applied to it. When the parent field is the root, that inherited hint doesn't
get defaultMaxAge applied because we don't run willResolveField for the root
query.
Includes a CHANGELOG update for #2197.
Since we already write to the persisted query cache asynchronously (and
intentionally do not await the Promise) this won't have any affect on the
current behavior of when the persisted query cache is written to in the
event of an executable request, but if an operation comes in and doesn't
parse or validate, we'll avoid wasting cache space on an operation that will
never execute.
Additionally, in a similar light, if a plugin throws an error which stops
execution, we can avoid the side-effect of writing to the persisted query
cache.
In terms of the APQ behavior, while this could cause additional round-trips
for a client which repeatedly sends an invalid operation, that operation is
never going to successfully finish anyway. While developer tooling will
help avoid this problem in the first place, this refusal to store an invalid
operation in the APQ cache could actually help diagnose a failure since the
full operation (rather than just the SHA256 of that document) will appear
in the browser's dev-tools on the retry.
If we're looking to spare parsing and validating documents which we know are
going to fail, I think that's going to be a better use of the (new)
`documentStore` cache (#2111), since its in-memory and can accommodate a
more complex data structure which includes the validation errors from the
previous attempt which will, of course, be the same when validating the same
operation against the same schema again. As the PR that introduced that
feature shows, sparing those additional parses and validations (cached APQ
documents still needs to be parsed and validated, currently) will provide a
more successful performance win overall.

- JavaScript: Do not format functions with arguments as react hooks ([#​5778] by [@​SimenB])
The formatting added in Prettier 1.16 would format any function receiving an
arrow function and an array literal to match React Hook's documentation.
Prettier will now format this the same as before that change if the arrow
function receives any arguments.

- JavaScript: Add necessary parentheses for decorators ([#​5785] by [@​ikatyang])
Parentheses for decorators with nested call expressions are optional for legacy decorators
but they're required for decorators in the current [proposal](https://tc39.github.io/proposal-decorators/#sec-syntax).
<!-- prettier-ignore -->
```js
// Input
class X {
@​(computed().volatile())
prop
}
// Output (Prettier 1.16.0)
class X {
@​computed().volatile()
prop
}
// Output (Prettier 1.16.1)
class X {
@​(computed().volatile())
prop
}
```
- TypeScript: Stable parentheses for function type in the return type of arrow function ([#​5790] by [@​ikatyang])
There's a regression introduced in 1.16 that
parentheses for function type in the return type of arrow function were kept adding/removing.
Their parentheses are always printed now.
<!-- prettier-ignore -->
```ts
// Input
const foo = (): (() => void) => (): void => null;
const bar = (): () => void => (): void => null;
// First Output (Prettier 1.16.0)
const foo = (): () => void => (): void => null;
const bar = (): (() => void) => (): void => null;
// Second Output (Prettier 1.16.0)
const foo = (): (() => void) => (): void => null;
const bar = (): () => void => (): void => null;
// Output (Prettier 1.16.1)
const foo = (): (() => void) => (): void => null;
const bar = (): (() => void) => (): void => null;
```
- MDX: Correctly recognize inline JSX ([#​5783] by [@​ikatyang])
Previously, some inline JSXs are wrongly recognized as block HTML/JSX,
which causes unexpected behaviors. This issue is now fixed.
<!-- prettier-ignore -->
```md
<!-- Input -->
_foo <InlineJSX /> bar_
<!-- Output (Prettier 1.16.0) -->
_foo
<InlineJSX /> bar_

* refactor: switch `json-stable-stringify` to `fast-json-stable-stringify`
* chore: drop `@types/json-stable-stringify`
* Update CHANGELOG.md for #2065.
This also re-enables the Expiration tests for this library, though I think I
will continue to leave the testsuite decomposed into more granular methods
for readability and future growth.
Note that this doesn't implement the same default `300` second TTL as the
other Memcache and Redis implementations currently do (a very debatable
default we should re-consider in the future).
While it is certainly our current implementation, I'm not sure that the true
spirit of an in-memory key-value store is to only map strings to other strings.
While enforcing `<string, string>` might be necessary for some distributed
cache stores, it seems we shouldn't enforce it for `InMemoryLRUCache`.
By changing the `KeyValueCache` to default to `string` but allow other
options, we can allow the user to decide exactly how the RHS of this store
should be typed.
This does require a bit more flexible implementation of the `length`
calculator which is used for cache ejection, but that implementation will
become immediately useful when we start storing parsed ASTs in this KV store.
Rather than crutching on the `return`, this logic reads more concisely with
a full `if` / `else` pattern.
I say this because two people looked at it and weren't immediately aware,
which really shouldn't be the case from such a brief piece of code.
This test harness is intended to be relatively temporary, but it seems
fruitful to start picking from where these types are already defined rather
than re-implementing them in multiple places.
This change came up in a larger feature implementation and should otherwise be
a no-op but was worth surfacing as its own commit in case that feature never
lands.
This fixes a TypeScript `TypeError` which was encountered after the
`@types/ws` typings were updated[[1]] to more correctly identify valid URLs.
The error exhibited on CI[[2] was:
TypeError [ERR_INVALID_URL]: Invalid URL: ws://localhost:6666undefined
This had been previously reverted[[3]] but was auto-merged again for a
reason I don't quite have time to investigate right now, though I suspect
it's something I'll be able to prevent in the future with a bit more care.

* AER: Remove encodedTraces to prevent duplicates
When there are multiple instances of apollo-engine-reporting, the
`Trace.encode` method gets wrapped each time to add the
`encodedTraces`. In order to prevent them from being added to the
protobuf multiple times, we remove the encodedTraces after adding them
once
* Add changelog
* Move incremental Trace encoding to a-e-r-protobuf
To enable incrmental compilation of traces, we add a patch to the
Trace.encode method generated by protobujs to accept and store encoded
traces. Occassionally with multiple instances of apollo-engine-reporting
that share the same version of the protobuf, the wrapper method gets
applied more than once. In order to ensure that the wrapper only gets
applied once, we patch the Trace.encode method inside of
apollo-engine-protobuf.
tsc hangs on the processing the generated protobuf.js files, so the
tsconfig.json ignores the generated protobuf file. In order for the
typescript index.ts file to compile the generated protobuf.js file is
output to the src folder. To ensure the protobuf files are available to
the production build, `npm run compile` copies the protobuf file
manually from src to dist.
* Reexport protobuf import after modification
`export * from './protobuf'` exports the unmodified reference
* Update comment on Trace.encode to point at a-e-r-p
The override now occurs inside of apollo-engine-reporting-protobuf due
to the case of having multiple reporting challenges, so we need to
update the comments to help indicate that
* Remove typescript build step
In order to simplify the generation of this library, we move the change
the index.ts file into index.js and remove the typescript build step.
Since the type safety is created by the protobufjs generation, this
seems acceptable. In general this portion of the code should remain
relatively stable, so generating and copying the code with `prepare`
remains reasonable.
This commit again looks quite complicated, but's merely an over-complication
inflicted by Prettification. Disabling whitespace differences when viewing
this commit, the functional change here is that we no longer skip many file
upload tests when the (semver) major segment of `process.version` is `10`.
I couldn't be happier to get rid of this exception for file upload tests on
Node.js 10, which was an unfortunate reality of the non-updated
`graphql-upload` module world we previously lived in.
Thanks, @jaydenseric, for the newfound (to us!) Node.js upload support!
This commit looks way more complicated than it really is thanks to Prettier
trying to be helpful.
All I've done is add `NODE_MAJOR_VERSION === 6` as a version NOT to test
uploads for, in an effort to fix the failing tests (failing appropriately
since Node.js 6 with file uploads throws an error right now and cannot run
uploads anymore.).
I hope to actually remove this limitation, but I'm going to iterate on it
first. This also just switches to a `NODE_MAJOR_VERSION` constant from the
`apollo-server-integration-testsuite` rather than using the GTE function on
the same input since...math.
