jsonschema-key-compression's Issues

Further compaction

Have you considered making the encoding even more efficient by omitted key names for required fields, altogether?

e.g.

{
    "firstName": "Corrine",
    "lastName": "Ziemann",
    "title": "Ms.",
    "gender": "f",
    "zipCode": 75963,
    "countryCode": "en",
    "birthYear": 1960,
    "active": false,
    "shoppingCartItems": [
        {
            "productNumber": 29857,
            "amount": 1
        },
        {
            "productNumber": 53409,
            "amount": 6
        }
    ]
}

could become

["Corrine", "Ziemann", "Mrs.", false, [
        [29857, 1],
        [53409, 6]
    ],{
    "gender": "f",
    "zipCode": 75963,
    "countryCode": "en",
    "birthYear": 1960
}
]

Assuming that gender, zipCode, etc. are optional and the other fields are marked as required.

It seems like this could reduce the file size quite significantly.

Also you could consider applying the compression of graphql-crunch, which re-uses prior values if they are repeated.

Build error when migrating from Rollup 1.x to 2.x (via StencilJS, RxDB)

Hey!

We are consuming [email protected] in a StencilJS app.

When building with @stencil/[email protected] (which uses [email protected]), the app builds without an issue.

If I bump the StencilJS dependency to >=@stencil/[email protected] (which uses >= [email protected]) the build fails with the following error:

[ ERROR ]  Rollup: Parse Error: ./node_modules/jsonschema-key-compression/src/compress.ts:12:9
           Unexpected token (Note that you need plugins to import files that are not JavaScript)

     L11:  export function compressObject(
     L12:      table: CompressionTable,
     L13:      obj: PlainJsonObject

If I then manually add the @rollup/plugin-typescript to the rollup build plugins, the build error changes, and is now:

[ ERROR ]  Rollup: Plugin Error
           Could not load
           /{REDACTED}/app/node_modules/jsonschema-key-compression/src/index.ts
           (imported by ./node_modules/rxdb/dist/es/plugins/key-compression.js): Debug Failure. False expression:
           Expected fileName to be present in command line (plugin: typescript, load)

stencil/[email protected] uses [email protected], whereas stencil/[email protected] and greater use [email protected] and I can see there a failed Renovate PR build bumping to [email protected] (#107). This may also have build step implications?

GH comparison for StencilJS versions, at the point at which the build starts to fail: ionic-team/stencil@v1.13.0...v1.14.0

There's a barebones repo highlighting the issue here: https://github.com/chrisweight/jsonschema-build-failure

You can comment out the typescript() plugin in stencil.config.ts to see the first error
