            Formats to use on a response with fast-json-stringify
            Asked 2021-Feb-10 at 14:22

            What I want to do is add validation to the schema response from a fastify route.

            Following the documentation from Fastify here we can see this

            Ajv for the validation of a request fast-json-stringify for the serialization of a response's body

            Related to improve and add validations for a response, what I want to do is check the schema when I send a response.

            fast-json-stringify support different options, included format, but if you read the documentation, they said that they support JSON schema. Jsonschema has support for email format, that you can see here as a built-in format but when I try to use it on Fastify, like this:

            fast-json-stringify does the serialization, not the validation.

            The json schema provided to it will be used to serialize only the properties declared and some type checking like integer or arrays.

            • the enum keyword is not supported
            • the format keyword is supported only for the dates as documented:

            To reach your goal, you should use this plugin: fastify-response-validation that will add a validation step of your response body before the serialization process.

            Like I can see you want to cache this JSON response.

            Add a cache key for this query. You need this to invalidate the response, when books change over the time.

            ES6 Async/Await, ExpressJS and Postgres transactions
            Asked 2020-Apr-11 at 07:16
            REVISED QUESTION

            I've revised the question, in the hope of getting a clearer answer.

            I'm trying to process data in ExpressJS, based on the incoming req.body and the existing data in the table.

            I'm receiving a req.body that contains a JSON list of updated fields. Some of those fields are stored as JSONB in Postgres. If an incoming field is JSONB, then the form (external code) that is making the request has already run a jsonpatch.compare() to generate the list of patches, and it is these patches and not the full values that are being passed in. For any non-JSONB values, incoming values just need to be passed through to the UPDATE query.

            I have a working version, as below, that pretends that the existing JSONB values in the table ARE NULL. Clearly, this is NOT what is needed. I need to pull the values from the db. The non-querying-of-current-values version and a bare minimum router, looks like this:

            Using the fast-json-patch library, I can get a JSON patch list easily enough in the client, and then something roughly thus:

            Answered 2020-Mar-28 at 13:53

            Use the 2nd method. PostgreSQL has no edit-in-place feature for JSONB. It is always going to include making a full copy. You might as well do that in the client, which seems to be have better tools for it.

            An exception might be if the patch is small and the JSONB is huge and your network is slow.

            Use web worker to stringify
            Asked 2020-Mar-24 at 22:30

            So I have an app that needs to JSON.stringify its data to put into localStorage, but as the data gets larger, this operation gets outrageously expensive.

            So, I tried moving this onto a webWorker so it's off the main thread, but I'm now learning posting an object to a webWorker is even more expensive than stringifying it.

            So I guess I'm asking, is there any way whatsoever to get JSON.stringify off the main thread, or at least make it less expensive?

            I'm familiar with fast-json-stringify, but I don't think I can feasibly provide a complete schema every time...

            ...

            ANSWER

            Answered 2020-Mar-24 at 22:30

            You have correctly observed that passing object to web worker costs as much as serializing it. This is because web workers also need to receive serialized data, not native JS objects, because the instance objects are bound to the JS thread they were created in.

            The generic solution is applicable to many programming problems: chose the right data structures when working with large datasets. When data gets larger it's better sacrifice simplicity of access for performance. Thus do any of:

            Store data in indexedDB

            If your large object contains lists of the same kind of entry, use indexed DB for reading and writing and you don't need to worry about serialization at all. This will require refactor of your code, but this is the correct solution for large datasets.

            Store data in ArrayBuffer

            If your data is mostly fixed-size values, use an ArrayBuffer. ArrayBuffer can be copied or moved to web worker pretty much instantly and if your entries are all same size, serialization can be done in parallel. For access, you may write simple wrappers classes that will translate your binary data into something more readable.

            Upgrading Webpack from 2.7 to 4.35 blank page IE11

I try not to upgrade every package but only Webpack and the ones that needed to upgrade for compatibility purpose. I also already tried Vue-CLI as it's a Vue project, but same issue.

            How to fix issue of incompatibility between angular project and a vega (charts library)?
            Asked 2019-Jun-16 at 08:26

            I'm currently working on a angular 7 project, and i want to add vega library for charts. the issue i think is the fact that vega requires a higher version of typescript (3.4.4) and inside my project its only (3.2.2).

            So when i try to run the project, i'm having an error like this :

            ERROR in node_modules/vega-lite/build/src/util.d.ts(1,10): error TS2305: Module '"P:/projects/ui/project/node_modules/@types/clone"' has no exported member 'default'. node_modules/vega-lite/build/src/util.d.ts(2,8): error TS1192: Module '"P:/projects/ui/project/node_modules/@types/fast-json-stable-stringify/index"' has no default export.

            so could be please give me an idea , how to solve this kind of issues , if you have lower version of typescript in your application and a higher one in another library.

            Angular 7 currently uses TypeScript 3.2.2 so your Angular TypeScript version is as expected.

            You could manually try changing the version of TypeScript in package.json then do an npm install and see what happens. If it errors out then it's going to be a problem for you.

            Another suggestion is you could switch to the release candidate for Angular 8.
