Config + Code Examples in Readme

[karlhorky]

Hi @Sec-ant , thanks for the great Prettier plugin! (and thanks @JounQin for prettier-plugin-sql, which also enables the formatting of SQL tagged template literals!)

Would be great to see a few complete config examples like the config code examples in comments in #16

Either:

A) full interactive examples (eg. CodeSandbox) or "recipes"
B) including configuration and code as in below

prettier.config.js

/** @type {import('prettier').Config} */
const prettierConfig = {
  plugins: ['prettier-plugin-embed', 'prettier-plugin-sql'],
};

/** @type {import('prettier-plugin-embed').PrettierPluginEmbedOptions} */
const prettierPluginEmbedConfig = {
  embeddedSqlIdentifiers: ['sql'],
}

/** @type {import('prettier-plugin-sql').SqlBaseOptions} */
const prettierPluginSqlConfig = {
  language: 'postgresql',
  keywordCase: 'upper',
}

const config = {
  ...prettierConfig,
  ...prettierPluginEmbedConfig,
  ...prettierPluginSqlConfig,
};

export default config;

index.ts (before)

const animals = await sql`
      SELECT
*                 
                       FROM
       animals
`;

index.ts (after)

const animals = await sql`
  SELECT
    *                 
  FROM
    animals
`;

If there are any further dependencies for prettier-plugin-sql such as @xml-tools/parser, as mentioned in my bug report about the plugin crash below, then maybe that would also be a good thing to add to the documentation.

• Cannot find package '@xml-tools/parser' #21
