vscode-graphql, LSP, IDE Roadmap 2022

The next chapter now that 2021/2020 LSP Roadmap is complete

This applies to graphql-language-service-server, vscode-graphql which will soon be merged with this monorepo, and many other IDE plugins who often utilize graphql-language-service-cli via python, lua, java, etc.

Suggestions are welcome in the comments, if you want to nominate any bugs, feature requests here or in vscode-graphql, or create an RFC and suggest one, please feel free to!

🐛 fixing bugs

• better error handling & logging
  • [] https://github.com/graphql/graphiql/pull/2161
• customize/patch graphql-config file loader to continue parsing despite failures on getDocuments()
• SDL files just don't work...
• graphql-config in package.json doesn't work
• graphql-config in .ts/tsx files doesn't work (graphql-config upgrade)
• #2068
• https://github.com/graphql/graphiql/issues/1894 (trigger characters implemented but should be revisted)
• /* GraphiQL */ tag doesn't work for highlighting in vscode-graphql (link to PR)
• https://github.com/graphql/graphiql/issues/2212
• https://github.com/graphql/graphiql/issues/2018
• workspaces support related issues - load graphql-config from workspace root? vscode-graphql may need proper handling of workspaces + graphql-config projects as well.
• dotenv issues (currently the workaround is to import dotenv directly in graphql config files)
• Windows paths, replace URL().basename approach with vscode-uri for vscode uri string parsing
• https://github.com/graphql/graphiql/issues/2182
• !!! https://github.com/graphql/graphiql/issues/2172
• !!! Parsing bug from getDocuments when documents is used (there are many duplicates)
• if a user provides documents in config, then that is what triggers graphqlConfig.getDocuments() currently. we also call this excessively. there are many duplicates of this

💯 new features

when adding changes to getAutocompleteSuggestions and other parts of graphql-language-service-interface, monaco-graphql will benefit!

• minimal schema-less support for all language features possible
  • schemaless validation rules
  • minimal schemaless completion
  • https://github.com/graphql/graphiql/issues/2174
• 💥 breaking change: new major version of interface modules that accepts object parameters to make it easier to deprecate and provide alternatives such as documentAST input and new config and APIs
• 💥 breaking change: graphql-language-service-interface, -types,, -parser and -utils should all be merged into the single graphql-language-service.
  • leave some waypoint for direct users of the -interface methods and other packages, for example a warning on install for the final release of these packages as they are deprecated. otherwise they will miss out on new features. a great example of one of our direct users of getAutocompleteSuggestions is postwoman!
• allow disabling validation in the language server or vscode-graphql: graphql/graphiql#2363
• support insertText for completion of object and list fields https://github.com/graphql/graphiql/issues/587
• support vue, svelte for syntax highlighting at least
• autocomplete field names for types/interface when using implements
• jump to source field name on implemented interface fields
• jump to definition for query fields and arguments
• getDiagnostics should allow an option for schema validation, or detect whether schema types are present to provide additional schema validation rules, or gather errors from graphql-js validateSchema
• graphql-language-service-server should send the lsp client instructive notifications about graphql-config - when it's detected, and when it's not, or when there are issues.
  • vscode-graphql should be configured to handle these notifications accordingly
• additional language support - vscode-graphql grammars and in graphql-language-service-server for completion, diagnostics, etc
  • this is a complicated feature but it deserves prioritization!
• TODO track down any new spec features that need to be implemented
• investigate usage of notebooks API

🤝 merge vscode-graphql with graphiql monorepo

• create issue menu & forms with options for reporting IDE vs web bugs/enhancement requests
• migrate issues
• migrate PRs
• migrate github actions & other automation

🌀 refactors

• refactor the language server to use graphql-tools and graphql-config completely, and replace parseDocument entirely with CodeFileLoader or a custom loader if needed.
• refactor the extension client to make it easier to build behavior around graphql-config

💻 e2e suite for vscode-graphql

using https://github.com/microsoft/vscode-extension-samples/tree/main/lsp-sample as a fantastic point of reference:

• test harness
• diagnostics
• completion
• all supported schema config combinations
• test configuration options
• run in CI
• test extension client behaviors

⚙️ automation

• fix open-vsx publish for vscode-graphql
• deploy previews for vscode-graphql
• canary releases to graphql.vscode-graphql-insiders (vsce also seems to support pre-release flag now?)
