Move create config functions out of the main delta-processor.ts file. Change some any types to more specific types. Define document structure better. Move prometheus logic out of processor class. Do not call logger directly, listen for events and log them. Change logger to more PSR-3 compliant style. Extract amqp connection into its own class. Create avro and mongo objects in factory.
Just trying to reduce some boilerplate. I kept this as a separate commit to
illustrate clearly how this type of things is done since we'll have people
learning TypeScript.
* src/types/misc.ts (NodeCallback<T,R>): New type.
* src/server/dapi/TokenedDataApi.ts: Use it.
* test/server/dapi/TokenedDataApiTest.ts: Use it.
This beings an experiment with nominal typing using what the TS community
calls "branding". The lack of nominal types was one of my biggest
disappointments with TS, so this should really help to mitigate bugs
resulting from misappropriation of data.
* src/server/token/Token.ts: New file.
* src/server/token/TokenDao.ts: Use Token{Id,Namespace}.
* src/server/token/TokenQueryResult.ts: Likewise.
* src/types/misc.d.ts: Introduce NominalType and UnixTimestamp.
* test/server/token/TokenDaoTest.ts: Use nominal types.
This tests the existing state of TokenDao before additional modifications
are made. This commit also further refines the types introduced in a
previous commit.
This is also the first test written in Typescript.
* package.json.in (devDependencies): Add node, chai, and mocha types.
* src/server/token/TokenDao.ts (updateToken): `data` accepts null (as it
should). Do not conditionall add data to object (it doesn't matter for
later retrieval). Note nondeterminism with date. More concise syntax
for object fields.
* src/server/token/TokenQueryResult.ts: Make all fields readonly.
(TokenStatus): Date is no longer optional (see above mention).
* src/types/mongodb.d.ts: Remove generics (erroneously added).
(Collection)[update]: Remove 3-argument declaration (see comment).
* test/server/token/TokenDaoTest.ts: New test case.
This adds type information for both MongoCollection and some details about
the structure of the data itself as it is stored in the database.
* src/server/token/TokenDao.ts: Import types from TokenQueryResult.
(TokenType): Move to TokenQueryResult module.
(TokenData)[status]: string=>TokenStatus.
(TokenDao)[_collection]: Remove optional type specifier.
[_collection]: Make readonly.
[updateToken]: Use TokenStatus type for token_entry.
[getToken]: Add return type. Add type for query result. Remove useless
length check (no such field exists). Add types for variables.
[_getLatestToken]: Use interface instead of inline type definition.
[_getRequestedToken]: Use type definition for `data' instead of
`any'. Add type of variable.
* src/server/token/TokenQueryResult.ts: Define structure of data in Mongo.
* src/types/mongodb.d.ts: Add type information for methods used by TokenDao.
This is the first test of integrating typescript. I'm using the `export ='
syntax to keep imports the same using `require', but note that the `new'
keyword is now required for instantiation (whereas it was not with easejs).
