Migrate from v6 to v7
Highcharts
For the major version upgrade to 7.0.0 we bumped the version of the peer
dependency highcharts to use version ^7.0.0. This version of highcharts is
the first version that comes with official typings for typescript. Previously we
had to use community typings that were outdated. This upgrade requires some
manual changes to be performed for those typings.
Most common typings from the previous version:
SeriesOptions
If you used SeriesOptions before, please use Options from highcharts or
DtChartOptions for the options part of the configuration.
IndividualSeriesOptions
If you used IndividualSeriesOptions before, please either use the
DtChartSeries type or use one of the types used in the union if you can be
more explicit, e.g. SeriesBarOptions, SeriesColumnOptions,
SeriesLineOptions, SeriesAreaOptions, SeriesArearangeOptions,
SeriesPieOptions. The dt-chart does not support other chart types.
DataPoint
If you used the DataPoint type before, in most cases the new type that fits in
highcharts 7 is PointOptionsObject.
lodash -> lodash-es
We switched the peer dependency of lodash to lodash-es to enable treeshaking
and reduce our bundle size. Our advice would be to also switch to lodash-es
for your app. If you are using jest as a testrunner as we do and encounter
problems with lodash-es because it does not ship commonjs bundles, you can add
the following snippet to your jest.config.js.
moduleNameMapper: {
// map lodash-es to lodash bundle since jest needs commonjs
'^lodash-es$': 'node_modules/lodash/index.js',
},
Note: You need to have lodash installed as a dev dependency as well, since
jest will take the lodash version for all lodash-es imports in your code.
Filter field
We improved the typings for our DtFilterFieldDefaultDatasource class. The
class is not a generic class anymore. Please remove the generic type and verify
that your code is compatible with our default datasource implementation. If you
want to use your own types for the filter field please create your own
datasource.
