@bahmutov/parcel-json-server

Combination of ParcelJs bundler and json-server

NPM

CircleCI semantic-release renovate-app badge

Install

Requires Node 10+ because of ParcelJS bundler

npm i -D @bahmutov/parcel-json-server

Use

  • create a JSON file to server as a database / REST api, see json-server documentation. For example see test/data.json
  • have an HTML with JavaScript, CSS, etc. for Parcel bundler to process and serve, for example see test/app/index.html
  • run parcel-json-server --entrypoint <path to HTML file> --database <path to JSON file> and get the app running at localhost:<port> with REST endpoints at localhost:<port>/<resource name>

Options

$ node ./src/cli.js --help
  Usage: cli.js [options] [command]

  Commands:
    help     Display help
    version  Display version

  Options:
    -d, --database    database JSON filename
    -e, --entrypoint  HTML filename to serve
    -h, --help        Output usage information
    -p, --port <n>    Port to run on (defaults to 3000)
    -v, --version     Output the version number

Example

In this repo the example npm start script runs

$ @bahmutov/parcel-json-server \
    --port 3000 \
    --entrypoint test/app/index.html \
    --database test/data.json

Then I can open localhost:3000 and see the application, and make calls to localhost:3000/todos (full REST endpoint)

To reset data, use POST /reset request, pass new data to overwrite ALL old data. For example, from a Cypress test cypress/integration/spec.js you can do the following

const todos = require('../../test/data.json').todos

it('responds from REST API', () => {
  cy.request('POST', '/reset', { todos })
  cy.request('/todos')
    .its('body')
    .should('deep.equal', todos)
})

Debugging

If you want to see debug messages, run with environment variable
