graphile-plugin-fulltext-filter

graphile-plugin-fulltext-filter adds full-text search operators for tsvector fields to graphile-plugin-connection-filter in PostGraphile v4.

🚀 Installation

pnpm add graphile-plugin-fulltext-filter

✨ Features

• Adds a matches operator for tsvector columns in PostGraphile v4
• Works alongside graphile-plugin-connection-filter
• Generates rank fields for ordering results (fullTextRank)
• CLI and library-friendly setup
• Uses pg-tsquery to safely parse user input

📦 Usage

CLI

postgraphile --append-plugins graphile-plugin-connection-filter,graphile-plugin-fulltext-filter

See here for more information about loading plugins with PostGraphile.

Library

const express = require('express');
const { postgraphile } = require('postgraphile');
const PostGraphileConnectionFilterPlugin = require('graphile-plugin-connection-filter');
const FulltextFilterPlugin = require('graphile-plugin-fulltext-filter');

const app = express();

app.use(
  postgraphile(pgConfig, schema, {
    appendPlugins: [
      PostGraphileConnectionFilterPlugin,
      FulltextFilterPlugin,
    ],
  })
);

app.listen(5000);

⚡ Performance

All tsvector columns that aren't @omit'd should have indexes on them:

ALTER TABLE posts ADD COLUMN full_text tsvector;
CREATE INDEX full_text_idx ON posts USING gin(full_text);

🔎 Operators

This plugin adds the matches filter operator to the filter plugin, accepting a GraphQL String input and using the @@ operator to perform full-text searches on tsvector columns.

This plugin uses pg-tsquery to parse the user input to prevent Postgres throwing on bad user input unnecessarily.

🧭 Fields

For each tsvector column, a rank column will be automatically added to the GraphQL type for the table by appending Rank to the end of the column's name. For example, a column full_text will appear as fullText in the GraphQL type, and a second column, fullTextRank will be added to the type as a Float.

This rank field can be used for ordering and is automatically added to the orderBy enum for the table.

🧪 Examples

query {
  allPosts(
    filter: {
      fullText: { matches: 'foo -bar' }
    }
    orderBy: FULL_TEXT_RANK_DESC
  ) {
    ...
    fullTextRank
  }
}

🧪 Testing

# requires a local Postgres available (defaults to postgres/password@localhost:5432)
pnpm --filter graphile-plugin-fulltext-filter test
