Evergreen API Explorer

This app displays metadata from the API of a running Evergreen server.


After launching the app, enter the hostname of an Evergreen system and click the “Connect to Evergreen” button. Once connected, choose an Evergreen service from the dropdown and optionally enter a search filter, then click the “Fetch API Information” button.


To build this app:

npm install

If you have a running Evergreen system, it is most convenient to then copy the compiled app somewhere under /openils/var/web. For example,

rsync -vaHx dist/ /openils/var/web/api-explorer/

The API explorer can then be found under https//HOST/api-explorer/.

If you need to run this app on a host different from your Evergreen server, at present some CORS headers need to be set on the Evergreen end:

<IfModule mod_headers.c>
    Header append Access-Control-Allow-Origin "*"
    Header append Access-Control-Allow-Headers "*"
    Header append Access-Control-Expose-Headers "*"

Note that these CORS settings may be more permissive than you would care to have in production.

A future version of the explorer may provide a proxy so that CORS considerations don’t apply.


Recommended IDE Setup

VSCode + Volar (and disable Vetur) + TypeScript Vue Plugin (Volar).

Type Support for .vue Imports in TS

TypeScript cannot handle type information for .vue imports by default, so we replace the tsc CLI with vue-tsc for type checking. In editors, we need TypeScript Vue Plugin (Volar) to make the TypeScript language service aware of .vue types.

If the standalone TypeScript plugin doesn’t feel fast enough to you, Volar has also implemented a Take Over Mode that is more performant. You can enable it by the following steps:

  1. Disable the built-in TypeScript Extension
    1. Run Extensions: Show Built-in Extensions from VSCode’s command palette
    2. Find TypeScript and JavaScript Language Features, right click and select Disable (Workspace)
  2. Reload the VSCode window by running Developer: Reload Window from the command palette.
